Let's divide 766240 by 90
Our goal is to divide 766240 by 90.

Let's proceed to step 1:
7 divided by 90 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 90

Going ahead to step 2:
90 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 90

Advancing to step 3:
The number 90 fits into 766 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 720 from 766, we get 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 90

Going ahead to step 4:
If we divide 462 by 90, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 450 from 462 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 90

On to step 5:
90 goes into 124 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 851.0
If we take 90 away from 124, we end up with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 90

On to step 6:
90 can be fit into 340 3 times, resulting in a remainder of 70.
The number 3 becomes the next digit in our result. 
Result so far: 8513.0
Subtracting 270 from 340 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 8513.7
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 8513.77
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 8513.77, and the remainder is 0.07.
