We look at the division of 53939172 by 811 
We're looking to find how many times 811 goes into 53939172.

Let's proceed to step 1:
5 divided by 811 is 0 with 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.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 811

Moving on to step 2:
When dividing 53 by 811, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 811

On to step 3:
If we divide 539 by 811, we get 0 and a remainder of 539.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 539 leaves us with 539.
Include the next digit (3) from the dividend after 539, then repeat: 5393 / 811

Let's proceed to step 4:
The number 811 fits into 5393 6 times, leaving a remainder of 527.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 4866 from 5393 leaves us with 527.
Take the next digit (9) from the dividend and append it to 527, then repeat: 5279 / 811

Going ahead to step 5:
811 goes into 5279 6 times with a remainder of 413.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we subtract 4866 from 5279, we get 413.
Bring next digit (1) of the dividend behind the 413 and repeat the process: 4131 / 811

Advancing to step 6:
When dividing 4131 by 811, we get 5 with a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 665.0
If we subtract 4055 from 4131, we get 76.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 811

Advancing to step 7:
When dividing 767 by 811, we get 0 with a remainder of 767.
Record the quotient 0 as the next digit in the result. 
Result so far: 6650.0
Subtracting 0 from 767 leaves us with 767.
Fetch the next digit (2) from the dividend, attach it to 767 and continue: 7672 / 811

On to step 8:
When dividing 7672 by 811, we get 9 with a remainder of 373.
Write down 9 as next digit of the result. 
Result so far: 66509.0
If we take 7299 away from 7672, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Let's proceed to step 9:
When dividing 3730 by 811, we get 4 with a remainder of 486.
Record the quotient 4 as the next digit in the result. 
Result so far: 66509.4
Deduct 3244 from 3730 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 10:
4860 divided by 811 is 5 with a remainder of 805.
Use 5 as the next digit of our solution. 
Result so far: 66509.45
Subtract 4055 from 4860 to get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 11:
811 can be fit into 8050 9 times, resulting in a remainder of 751.
The number 9 becomes the next digit in our result. 
Result so far: 66509.459
Subtract 7299 from 8050 to get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

On to step 12:
If we divide 7510 by 811, we get 9 and a remainder of 211.
Write down 9 as next digit of the result. 
Result so far: 66509.4599
Deduct 7299 from 7510 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The quotient of the division is 66509.4599, and the remainder is 0.00211.
