55956131 ÷ 521 
We're looking to find how many times 521 goes into 55956131.

On to step 1:
The number 521 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 521

On to step 2:
When dividing 55 by 521, we get 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (9) of the dividend behind the 55 and repeat the process: 559 / 521

Advancing to step 3:
The number 521 fits into 559 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 521 from 559, we get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 521

On to step 4:
If we divide 385 by 521, we get 0 and a remainder of 385.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 385 leaves us with 385.
Bring next digit (6) of the dividend behind the 385 and repeat the process: 3856 / 521

Advancing to step 5:
The number 521 fits into 3856 7 times, leaving a remainder of 209.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 3647 away from 3856, we end up with 209.
Take the next digit (1) from the dividend and append it to 209, then repeat: 2091 / 521

Let's proceed to step 6:
2091 divided by 521 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 1074.0
If we take 2084 away from 2091, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 521

Moving on to step 7:
521 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 10740.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 521

Moving on to step 8:
The number 521 fits into 731 1 times, leaving a remainder of 210.
The number 1 becomes the next digit in our result. 
Result so far: 107401.0
If we take 521 away from 731, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
The number 521 fits into 2100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 107401.4
Subtract 2084 from 2100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 521 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 107401.4
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
The number 521 fits into 1600 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 107401.403
Subtract 1563 from 1600 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
When dividing 370 by 521, we get 0 with a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 107401.403
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 13:
If we divide 3700 by 521, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 107401.40307
If we take 3647 away from 3700, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
If we divide 530 by 521, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 107401.403071
Subtract 521 from 530 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 15:
If we divide 90 by 521, we get 0 and a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 107401.403071
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 16:
521 goes into 900 1 times with a remainder of 379.
Record the quotient 1 as the next digit in the result. 
Result so far: 107401.40307101
If we take 521 away from 900, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

After the division, we end up with 107401.40307101 and a remainder of 3.79e-07.
