We look at the division of 51972914 by 831 
We want to figure out the number of times 51972914 can be divided by 831.

Step 1:
831 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 831

Going ahead to step 2:
The number 831 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 831

On to step 3:
519 divided by 831 is 0 with a remainder of 519.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 519, we end up with 519.
Bring next digit (7) of the dividend behind the 519 and repeat the process: 5197 / 831

Moving on to step 4:
When dividing 5197 by 831, we get 6 with a remainder of 211.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 4986 from 5197, we get 211.
Grab the next digit (2) from the dividend, add it to 211, then carry on: 2112 / 831

On to step 5:
If we divide 2112 by 831, we get 2 and a remainder of 450.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 1662 from 2112 leaves us with 450.
Take the next digit (9) from the dividend and append it to 450, then repeat: 4509 / 831

Step 6:
831 goes into 4509 5 times with a remainder of 354.
Use 5 as the next digit of our solution. 
Result so far: 625.0
If we take 4155 away from 4509, we end up with 354.
Append the next digit (1) from the dividend to 354 and continue with: 3541 / 831

Moving on to step 7:
The number 831 fits into 3541 4 times, leaving a remainder of 217.
The next digit of our result is 4. 
Result so far: 6254.0
If we subtract 3324 from 3541, we get 217.
Take the next digit (4) from the dividend and append it to 217, then repeat: 2174 / 831

Moving on to step 8:
If we divide 2174 by 831, we get 2 and a remainder of 512.
Record the quotient 2 as the next digit in the result. 
Result so far: 62542.0
Subtract 1662 from 2174 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 9:
5120 divided by 831 is 6 with a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 62542.6
Subtract 4986 from 5120 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 10:
831 goes into 1340 1 times with a remainder of 509.
Use 1 as the next digit of our solution. 
Result so far: 62542.61
The remainder is 509 after subtracting 831 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 11:
If we divide 5090 by 831, we get 6 and a remainder of 104.
Write down 6 as next digit of the result. 
Result so far: 62542.616
If we take 4986 away from 5090, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
831 can be fit into 1040 1 times, resulting in a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 62542.6161
Deduct 831 from 1040 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 13:
If we divide 2090 by 831, we get 2 and a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 62542.61612
The remainder is 428 after subtracting 1662 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 14:
The number 831 fits into 4280 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 62542.616125
The remainder is 125 after subtracting 4155 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 15:
831 goes into 1250 1 times with a remainder of 419.
Write down 1 as next digit of the result. 
Result so far: 62542.6161251
If we subtract 831 from 1250, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 16:
The number 831 fits into 4190 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 62542.61612515
Deduct 4155 from 4190 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 62542.61612515 with a remaining 3.5e-08.
