We're dividing 91729787 by 521 
Our goal is to divide 91729787 by 521.

Moving on to step 1:
If we divide 9 by 521, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 521

On to step 2:
If we divide 91 by 521, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 521

On to step 3:
521 goes into 917 1 times with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 521 from 917 to get 396.
Fetch the next digit (2) from the dividend, attach it to 396 and continue: 3962 / 521

Moving on to step 4:
521 goes into 3962 7 times with a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3647 from 3962 and we're left with 315.
Grab the next digit (9) from the dividend, add it to 315, then carry on: 3159 / 521

Moving on to step 5:
The number 521 fits into 3159 6 times, leaving a remainder of 33.
The next digit of our result is 6. 
Result so far: 176.0
Subtract 3126 from 3159 to get 33.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 521

Advancing to step 6:
337 divided by 521 is 0 with a remainder of 337.
Use 0 as the next digit of our solution. 
Result so far: 1760.0
If we subtract 0 from 337, we get 337.
Take the next digit (8) from the dividend and append it to 337, then repeat: 3378 / 521

Going ahead to step 7:
521 goes into 3378 6 times with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 17606.0
The remainder is 252 after subtracting 3126 from 3378.
Include the next digit (7) from the dividend after 252, then repeat: 2527 / 521

Advancing to step 8:
The number 521 fits into 2527 4 times, leaving a remainder of 443.
The number 4 becomes the next digit in our result. 
Result so far: 176064.0
If we subtract 2084 from 2527, we get 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Step 9:
The number 521 fits into 4430 8 times, leaving a remainder of 262.
The next digit of our result is 8. 
Result so far: 176064.8
Subtracting 4168 from 4430 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
2620 divided by 521 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 176064.85
If we take 2605 away from 2620, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
150 divided by 521 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 176064.85
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
When dividing 1500 by 521, we get 2 with a remainder of 458.
Put 2 as the next digit of the answer. 
Result so far: 176064.8502
If we subtract 1042 from 1500, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 13:
521 goes into 4580 8 times with a remainder of 412.
Put 8 as the next digit of the answer. 
Result so far: 176064.85028
The remainder is 412 after subtracting 4168 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 14:
When dividing 4120 by 521, we get 7 with a remainder of 473.
Put 7 as the next digit of the answer. 
Result so far: 176064.850287
Deduct 3647 from 4120 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 15:
521 goes into 4730 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 176064.8502879
The remainder is 41 after subtracting 4689 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 16:
If we divide 410 by 521, we get 0 and a remainder of 410.
The number 0 becomes the next digit in our result. 
Result so far: 176064.8502879
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The quotient of the division is 176064.8502879, and the remainder is 4.1e-07.
