68239143 divided by 313 
We want to divide 68239143 by 313.

Step 1:
313 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 313

On to step 2:
The number 313 fits into 68 0 times, leaving a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 313

On to step 3:
682 divided by 313 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 56 after subtracting 626 from 682.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 313

On to step 4:
When dividing 563 by 313, we get 1 with a remainder of 250.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 313 from 563 leaves us with 250.
Append the next digit (9) from the dividend to 250 and continue with: 2509 / 313

Step 5:
2509 divided by 313 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 218.0
The remainder is 5 after subtracting 2504 from 2509.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 313

Let's proceed to step 6:
When dividing 51 by 313, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 2180.0
If we take 0 away from 51, we end up with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 313

Going ahead to step 7:
If we divide 514 by 313, we get 1 and a remainder of 201.
The next digit of our result is 1. 
Result so far: 21801.0
If we take 313 away from 514, we end up with 201.
Grab the next digit (3) from the dividend, add it to 201, then carry on: 2013 / 313

Step 8:
When dividing 2013 by 313, we get 6 with a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 218016.0
If we take 1878 away from 2013, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
1350 divided by 313 is 4 with a remainder of 98.
The next digit of our result is 4. 
Result so far: 218016.4
The remainder is 98 after subtracting 1252 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
When dividing 980 by 313, we get 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 218016.43
The remainder is 41 after subtracting 939 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
410 divided by 313 is 1 with a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 218016.431
The remainder is 97 after subtracting 313 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 12:
313 goes into 970 3 times with a remainder of 31.
The next digit of our result is 3. 
Result so far: 218016.4313
Subtracting 939 from 970 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
313 can be fit into 310 0 times, resulting in a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 218016.4313
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 14:
The number 313 fits into 3100 9 times, leaving a remainder of 283.
Record the quotient 9 as the next digit in the result. 
Result so far: 218016.431309
Deduct 2817 from 3100 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 15:
2830 divided by 313 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 218016.4313099
Subtracting 2817 from 2830 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 218016.4313099 with a remaining 1.3e-07.
