We look at the division of 52509973 by 311 
We want to figure out the number of times 52509973 can be divided by 311.

Step 1:
When dividing 5 by 311, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 311

Let's proceed to step 2:
52 divided by 311 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 311

Advancing to step 3:
If we divide 525 by 311, we get 1 and a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 214 after subtracting 311 from 525.
Grab the next digit (0) from the dividend, add it to 214, then carry on: 2140 / 311

Moving on to step 4:
The number 311 fits into 2140 6 times, leaving a remainder of 274.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 1866 from 2140 to get 274.
Append the next digit (9) from the dividend to 274 and continue with: 2749 / 311

Step 5:
2749 divided by 311 is 8 with a remainder of 261.
Put 8 as the next digit of the answer. 
Result so far: 168.0
Deduct 2488 from 2749 and we're left with 261.
Take the next digit (9) from the dividend and append it to 261, then repeat: 2619 / 311

Going ahead to step 6:
The number 311 fits into 2619 8 times, leaving a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 1688.0
If we subtract 2488 from 2619, we get 131.
Take the next digit (7) from the dividend and append it to 131, then repeat: 1317 / 311

Advancing to step 7:
When dividing 1317 by 311, we get 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 16884.0
If we take 1244 away from 1317, we end up with 73.
Grab the next digit (3) from the dividend, add it to 73, then carry on: 733 / 311

Advancing to step 8:
311 can be fit into 733 2 times, resulting in a remainder of 111.
Put 2 as the next digit of the answer. 
Result so far: 168842.0
If we take 622 away from 733, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
311 goes into 1110 3 times with a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 168842.3
If we subtract 933 from 1110, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 10:
1770 divided by 311 is 5 with a remainder of 215.
The next digit of our result is 5. 
Result so far: 168842.35
Subtracting 1555 from 1770 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 11:
311 goes into 2150 6 times with a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 168842.356
Subtracting 1866 from 2150 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 12:
311 can be fit into 2840 9 times, resulting in a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 168842.3569
If we subtract 2799 from 2840, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
When dividing 410 by 311, we get 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 168842.35691
Subtract 311 from 410 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 14:
311 goes into 990 3 times with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 168842.356913
If we subtract 933 from 990, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 15:
The number 311 fits into 570 1 times, leaving a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 168842.3569131
Deduct 311 from 570 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 16:
The number 311 fits into 2590 8 times, leaving a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 168842.35691318
Subtract 2488 from 2590 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 168842.35691318 with a remaining 1.02e-07.
