We divide 981663 by 31
We're looking to find how many times 31 goes into 981663.

Step 1:
31 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 31

Let's proceed to step 2:
31 can be fit into 98 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 93 away from 98, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 31

Step 3:
31 goes into 51 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
The remainder is 20 after subtracting 31 from 51.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 31

On to step 4:
When dividing 206 by 31, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 316.0
Subtract 186 from 206 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 31

Going ahead to step 5:
When dividing 206 by 31, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3166.0
Deduct 186 from 206 and we're left with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 31

Advancing to step 6:
The number 31 fits into 203 6 times, leaving a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 31666.0
Subtract 186 from 203 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 31, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 31666.5
Subtract 155 from 170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
31 goes into 150 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 31666.54
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 31666.548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 31 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 31666.5483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
If we divide 270 by 31, we get 8 and a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 31666.54838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 31666.548387
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
31 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 31666.548387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
31 goes into 300 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 31666.54838709
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 31666.54838709 with a remaining 2.1e-08.
