We divide 66590679 by 766
Our goal is to divide 66590679 by 766.

On to step 1:
If we divide 6 by 766, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 766

On to step 2:
766 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 766

On to step 3:
If we divide 665 by 766, we get 0 and a remainder of 665.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 665 after subtracting 0 from 665.
Grab the next digit (9) from the dividend, add it to 665, then carry on: 6659 / 766

On to step 4:
The number 766 fits into 6659 8 times, leaving a remainder of 531.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6128 away from 6659, we end up with 531.
Append the next digit (0) from the dividend to 531 and continue with: 5310 / 766

On to step 5:
If we divide 5310 by 766, we get 6 and a remainder of 714.
Write down 6 as next digit of the result. 
Result so far: 86.0
The remainder is 714 after subtracting 4596 from 5310.
Include the next digit (6) from the dividend after 714, then repeat: 7146 / 766

Moving on to step 6:
If we divide 7146 by 766, we get 9 and a remainder of 252.
Use 9 as the next digit of our solution. 
Result so far: 869.0
If we take 6894 away from 7146, we end up with 252.
Grab the next digit (7) from the dividend, add it to 252, then carry on: 2527 / 766

Advancing to step 7:
When dividing 2527 by 766, we get 3 with a remainder of 229.
The number 3 becomes the next digit in our result. 
Result so far: 8693.0
Deduct 2298 from 2527 and we're left with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 766

Going ahead to step 8:
2299 divided by 766 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 86933.0
Subtracting 2298 from 2299 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
766 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 86933.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 766, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 86933.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 86933.0 with a remaining 0.1.
