Let's divide 55517321 by 812
We want to figure out the number of times 55517321 can be divided by 812.

Advancing to step 1:
The number 812 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 812

Step 2:
812 goes into 55 0 times with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 812

On to step 3:
555 divided by 812 is 0 with a remainder of 555.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 555 leaves us with 555.
Fetch the next digit (1) from the dividend, attach it to 555 and continue: 5551 / 812

Moving on to step 4:
The number 812 fits into 5551 6 times, leaving a remainder of 679.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4872 from 5551 leaves us with 679.
Grab the next digit (7) from the dividend, add it to 679, then carry on: 6797 / 812

Advancing to step 5:
When dividing 6797 by 812, we get 8 with a remainder of 301.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 6496 away from 6797, we end up with 301.
Fetch the next digit (3) from the dividend, attach it to 301 and continue: 3013 / 812

On to step 6:
If we divide 3013 by 812, we get 3 and a remainder of 577.
Use 3 as the next digit of our solution. 
Result so far: 683.0
Subtract 2436 from 3013 to get 577.
Take the next digit (2) from the dividend and append it to 577, then repeat: 5772 / 812

Let's proceed to step 7:
5772 divided by 812 is 7 with a remainder of 88.
The next digit of our result is 7. 
Result so far: 6837.0
Deduct 5684 from 5772 and we're left with 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 812

Advancing to step 8:
The number 812 fits into 881 1 times, leaving a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 68371.0
Deduct 812 from 881 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 9:
If we divide 690 by 812, we get 0 and a remainder of 690.
Record the quotient 0 as the next digit in the result. 
Result so far: 68371.0
The remainder is 690 after subtracting 0 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
6900 divided by 812 is 8 with a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 68371.08
If we take 6496 away from 6900, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 11:
When dividing 4040 by 812, we get 4 with a remainder of 792.
Write down 4 as next digit of the result. 
Result so far: 68371.084
Subtract 3248 from 4040 to get 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Step 12:
If we divide 7920 by 812, we get 9 and a remainder of 612.
Use 9 as the next digit of our solution. 
Result so far: 68371.0849
Deduct 7308 from 7920 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 13:
If we divide 6120 by 812, we get 7 and a remainder of 436.
The next digit of our result is 7. 
Result so far: 68371.08497
If we subtract 5684 from 6120, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 14:
812 can be fit into 4360 5 times, resulting in a remainder of 300.
The next digit of our result is 5. 
Result so far: 68371.084975
Subtracting 4060 from 4360 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 15:
812 can be fit into 3000 3 times, resulting in a remainder of 564.
The number 3 becomes the next digit in our result. 
Result so far: 68371.0849753
Subtract 2436 from 3000 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 16:
812 goes into 5640 6 times with a remainder of 768.
Put 6 as the next digit of the answer. 
Result so far: 68371.08497536
If we subtract 4872 from 5640, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Our division results in 68371.08497536 with a remaining 7.68e-07.
