Let's divide 51405821 by 313
Let's see how many times 313 fits into 51405821.

Step 1:
If we divide 5 by 313, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 313

On to step 2:
51 divided by 313 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 313

Going ahead to step 3:
514 divided by 313 is 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 313 from 514 to get 201.
Grab the next digit (0) from the dividend, add it to 201, then carry on: 2010 / 313

Advancing to step 4:
313 goes into 2010 6 times with a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 1878 away from 2010, we end up with 132.
Bring next digit (5) of the dividend behind the 132 and repeat the process: 1325 / 313

Going ahead to step 5:
When dividing 1325 by 313, we get 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we subtract 1252 from 1325, we get 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 313

Advancing to step 6:
The number 313 fits into 738 2 times, leaving a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 1642.0
If we subtract 626 from 738, we get 112.
Bring next digit (2) of the dividend behind the 112 and repeat the process: 1122 / 313

Step 7:
The number 313 fits into 1122 3 times, leaving a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 16423.0
If we subtract 939 from 1122, we get 183.
Take the next digit (1) from the dividend and append it to 183, then repeat: 1831 / 313

Moving on to step 8:
1831 divided by 313 is 5 with a remainder of 266.
Write down 5 as next digit of the result. 
Result so far: 164235.0
Deduct 1565 from 1831 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 9:
2660 divided by 313 is 8 with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 164235.8
If we take 2504 away from 2660, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 10:
If we divide 1560 by 313, we get 4 and a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 164235.84
Subtracting 1252 from 1560 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 11:
The number 313 fits into 3080 9 times, leaving a remainder of 263.
Write down 9 as next digit of the result. 
Result so far: 164235.849
If we subtract 2817 from 3080, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 12:
313 can be fit into 2630 8 times, resulting in a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 164235.8498
Subtract 2504 from 2630 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 13:
313 goes into 1260 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 164235.84984
Subtracting 1252 from 1260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 313, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 164235.84984
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
When dividing 800 by 313, we get 2 with a remainder of 174.
Record the quotient 2 as the next digit in the result. 
Result so far: 164235.8498402
If we take 626 away from 800, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 16:
When dividing 1740 by 313, we get 5 with a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 164235.84984025
Subtracting 1565 from 1740 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 164235.84984025 with a remaining 1.75e-07.
