We look at the division of 91293774 by 521 
We're looking to find how many times 521 goes into 91293774.

Let's proceed to step 1:
9 divided by 521 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 521

Moving on to step 2:
The number 521 fits into 91 0 times, leaving a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 521

Let's proceed to step 3:
When dividing 912 by 521, we get 1 with a remainder of 391.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 521 away from 912, we end up with 391.
Include the next digit (9) from the dividend after 391, then repeat: 3919 / 521

Going ahead to step 4:
3919 divided by 521 is 7 with a remainder of 272.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 3647 from 3919, we get 272.
Take the next digit (3) from the dividend and append it to 272, then repeat: 2723 / 521

Moving on to step 5:
When dividing 2723 by 521, we get 5 with a remainder of 118.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
If we subtract 2605 from 2723, we get 118.
Fetch the next digit (7) from the dividend, attach it to 118 and continue: 1187 / 521

Step 6:
When dividing 1187 by 521, we get 2 with a remainder of 145.
Put 2 as the next digit of the answer. 
Result so far: 1752.0
Deduct 1042 from 1187 and we're left with 145.
Grab the next digit (7) from the dividend, add it to 145, then carry on: 1457 / 521

Step 7:
1457 divided by 521 is 2 with a remainder of 415.
Put 2 as the next digit of the answer. 
Result so far: 17522.0
The remainder is 415 after subtracting 1042 from 1457.
Bring next digit (4) of the dividend behind the 415 and repeat the process: 4154 / 521

Moving on to step 8:
When dividing 4154 by 521, we get 7 with a remainder of 507.
The number 7 becomes the next digit in our result. 
Result so far: 175227.0
Deduct 3647 from 4154 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 9:
521 can be fit into 5070 9 times, resulting in a remainder of 381.
Write down 9 as next digit of the result. 
Result so far: 175227.9
Subtract 4689 from 5070 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 10:
521 goes into 3810 7 times with a remainder of 163.
The next digit of our result is 7. 
Result so far: 175227.97
Deduct 3647 from 3810 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 11:
If we divide 1630 by 521, we get 3 and a remainder of 67.
The next digit of our result is 3. 
Result so far: 175227.973
If we take 1563 away from 1630, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 12:
521 goes into 670 1 times with a remainder of 149.
Put 1 as the next digit of the answer. 
Result so far: 175227.9731
If we subtract 521 from 670, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 13:
1490 divided by 521 is 2 with a remainder of 448.
The number 2 becomes the next digit in our result. 
Result so far: 175227.97312
Subtracting 1042 from 1490 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 14:
4480 divided by 521 is 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 175227.973128
Subtracting 4168 from 4480 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 15:
When dividing 3120 by 521, we get 5 with a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 175227.9731285
If we subtract 2605 from 3120, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 16:
521 goes into 5150 9 times with a remainder of 461.
Use 9 as the next digit of our solution. 
Result so far: 175227.97312859
Deduct 4689 from 5150 and we're left with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

After the division, we end up with 175227.97312859 and a remainder of 4.61e-07.
