Let's divide 99056865 by 521
Our goal is to divide 99056865 by 521.

Advancing to step 1:
521 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 521

On to step 2:
If we divide 99 by 521, we get 0 and a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 521

Step 3:
990 divided by 521 is 1 with a remainder of 469.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 521 from 990 and we're left with 469.
Take the next digit (5) from the dividend and append it to 469, then repeat: 4695 / 521

Let's proceed to step 4:
When dividing 4695 by 521, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 4689 from 4695 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 521

Going ahead to step 5:
When dividing 66 by 521, we get 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we take 0 away from 66, we end up with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 521

On to step 6:
The number 521 fits into 668 1 times, leaving a remainder of 147.
Write down 1 as next digit of the result. 
Result so far: 1901.0
Subtracting 521 from 668 leaves us with 147.
Append the next digit (6) from the dividend to 147 and continue with: 1476 / 521

On to step 7:
The number 521 fits into 1476 2 times, leaving a remainder of 434.
Use 2 as the next digit of our solution. 
Result so far: 19012.0
Subtract 1042 from 1476 to get 434.
Grab the next digit (5) from the dividend, add it to 434, then carry on: 4345 / 521

On to step 8:
If we divide 4345 by 521, we get 8 and a remainder of 177.
Record the quotient 8 as the next digit in the result. 
Result so far: 190128.0
Deduct 4168 from 4345 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 9:
The number 521 fits into 1770 3 times, leaving a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 190128.3
Deduct 1563 from 1770 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 10:
2070 divided by 521 is 3 with a remainder of 507.
Write down 3 as next digit of the result. 
Result so far: 190128.33
If we subtract 1563 from 2070, we get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Our division results in 190128.33 with a remaining 0.507.
