Let's divide 31309568 by 981
Our goal is to divide 31309568 by 981.

On to step 1:
981 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 981

Moving on to step 2:
If we divide 31 by 981, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 981

Going ahead to step 3:
313 divided by 981 is 0 with a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 313, we get 313.
Include the next digit (0) from the dividend after 313, then repeat: 3130 / 981

Advancing to step 4:
981 can be fit into 3130 3 times, resulting in a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2943 from 3130 and we're left with 187.
Fetch the next digit (9) from the dividend, attach it to 187 and continue: 1879 / 981

Advancing to step 5:
1879 divided by 981 is 1 with a remainder of 898.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 981 from 1879 leaves us with 898.
Grab the next digit (5) from the dividend, add it to 898, then carry on: 8985 / 981

Step 6:
981 goes into 8985 9 times with a remainder of 156.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
If we subtract 8829 from 8985, we get 156.
Take the next digit (6) from the dividend and append it to 156, then repeat: 1566 / 981

Let's proceed to step 7:
If we divide 1566 by 981, we get 1 and a remainder of 585.
The number 1 becomes the next digit in our result. 
Result so far: 3191.0
Deduct 981 from 1566 and we're left with 585.
Fetch the next digit (8) from the dividend, attach it to 585 and continue: 5858 / 981

On to step 8:
981 can be fit into 5858 5 times, resulting in a remainder of 953.
The number 5 becomes the next digit in our result. 
Result so far: 31915.0
If we subtract 4905 from 5858, we get 953.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9530, and continue the process.

Step 9:
981 goes into 9530 9 times with a remainder of 701.
Record the quotient 9 as the next digit in the result. 
Result so far: 31915.9
Deduct 8829 from 9530 and we're left with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Step 10:
981 goes into 7010 7 times with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 31915.97
If we subtract 6867 from 7010, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 11:
981 goes into 1430 1 times with a remainder of 449.
The number 1 becomes the next digit in our result. 
Result so far: 31915.971
If we subtract 981 from 1430, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 12:
The number 981 fits into 4490 4 times, leaving a remainder of 566.
The next digit of our result is 4. 
Result so far: 31915.9714
If we subtract 3924 from 4490, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 13:
If we divide 5660 by 981, we get 5 and a remainder of 755.
Put 5 as the next digit of the answer. 
Result so far: 31915.97145
Subtracting 4905 from 5660 leaves us with 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

On to step 14:
When dividing 7550 by 981, we get 7 with a remainder of 683.
The next digit of our result is 7. 
Result so far: 31915.971457
If we take 6867 away from 7550, we end up with 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Going ahead to step 15:
If we divide 6830 by 981, we get 6 and a remainder of 944.
Use 6 as the next digit of our solution. 
Result so far: 31915.9714576
Subtract 5886 from 6830 to get 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

On to step 16:
If we divide 9440 by 981, we get 9 and a remainder of 611.
Use 9 as the next digit of our solution. 
Result so far: 31915.97145769
Subtract 8829 from 9440 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

After the division, we end up with 31915.97145769 and a remainder of 6.11e-07.
