159630 divided by 31 
Let's see how many times 31 fits into 159630.

Going ahead to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 31

Advancing to step 2:
The number 31 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 31

Step 3:
When dividing 159 by 31, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 155 from 159, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 31

Moving on to step 4:
46 divided by 31 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 31 away from 46, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 31

Advancing to step 5:
153 divided by 31 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
The remainder is 29 after subtracting 124 from 153.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 31

Going ahead to step 6:
31 can be fit into 290 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 5149.0
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
31 can be fit into 110 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 5149.3
If we subtract 93 from 110, we 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.

Advancing to step 8:
The number 31 fits into 170 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5149.35
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 5149.354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
If we divide 260 by 31, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5149.3548
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.

Moving on to step 11:
120 divided by 31 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 5149.35483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 5149.354838
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.

Going ahead to step 13:
31 goes into 220 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 5149.3548387
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.

On to step 14:
31 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5149.3548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 5149.3548387 with a remainder of 3e-08.
