55213187 ÷ 811 
We're looking to find how many times 811 goes into 55213187.

Let's proceed to step 1:
When dividing 5 by 811, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 811

On to step 2:
If we divide 55 by 811, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 811

Let's proceed to step 3:
811 can be fit into 552 0 times, resulting in a remainder of 552.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 552 after subtracting 0 from 552.
Take the next digit (1) from the dividend and append it to 552, then repeat: 5521 / 811

Let's proceed to step 4:
811 can be fit into 5521 6 times, resulting in a remainder of 655.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 4866 from 5521, we get 655.
Append the next digit (3) from the dividend to 655 and continue with: 6553 / 811

Advancing to step 5:
If we divide 6553 by 811, we get 8 and a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 6488 from 6553, we get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 811

On to step 6:
If we divide 651 by 811, we get 0 and a remainder of 651.
Put 0 as the next digit of the answer. 
Result so far: 680.0
Deduct 0 from 651 and we're left with 651.
Fetch the next digit (8) from the dividend, attach it to 651 and continue: 6518 / 811

Advancing to step 7:
6518 divided by 811 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 6808.0
If we subtract 6488 from 6518, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 811

Going ahead to step 8:
When dividing 307 by 811, we get 0 with a remainder of 307.
Use 0 as the next digit of our solution. 
Result so far: 68080.0
Subtracting 0 from 307 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
If we divide 3070 by 811, we get 3 and a remainder of 637.
Record the quotient 3 as the next digit in the result. 
Result so far: 68080.3
If we subtract 2433 from 3070, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 10:
If we divide 6370 by 811, we get 7 and a remainder of 693.
The number 7 becomes the next digit in our result. 
Result so far: 68080.37
Subtract 5677 from 6370 to get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Going ahead to step 11:
If we divide 6930 by 811, we get 8 and a remainder of 442.
Put 8 as the next digit of the answer. 
Result so far: 68080.378
If we subtract 6488 from 6930, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 12:
4420 divided by 811 is 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 68080.3785
Subtracting 4055 from 4420 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 13:
When dividing 3650 by 811, we get 4 with a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 68080.37854
If we take 3244 away from 3650, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 14:
When dividing 4060 by 811, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 68080.378545
Deduct 4055 from 4060 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
811 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 68080.378545
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 16:
811 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 68080.378545
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 68080.378545 with a remaining 5e-07.
