10d)

Read off the dividend until we get a bigger number than the divisor. In this case that happens in the eight's place. By trial and error we discover that the digit in the eight's place is 4

When we subtract and bring down the next digit,

the remainder is smaller than the divisor. We will not be able to take any more 35's from the dividend, so put a 0 in the one's place in the quotient.

and the remainder is 5.
