624987 ÷ 31 
We want to divide 624987 by 31.

Going ahead to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 31

Step 2:
The number 31 fits into 62 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 62 from 62.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 31

Going ahead to step 3:
31 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 31

Advancing to step 4:
31 goes into 49 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 201.0
The remainder is 18 after subtracting 31 from 49.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 31

On to step 5:
If we divide 188 by 31, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 2016.0
If we subtract 186 from 188, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 31

Let's proceed to step 6:
27 divided by 31 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 20160.0
If we take 0 away from 27, we end up 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.

Moving on to step 7:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 20160.8
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
If we divide 220 by 31, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 20160.87
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
If we divide 30 by 31, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 20160.87
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.

Advancing to step 10:
31 goes into 300 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 20160.8709
If we take 279 away from 300, we end up 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.

Step 11:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 20160.87096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 20160.870967
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
31 goes into 230 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 20160.8709677
The remainder is 13 after subtracting 217 from 230.
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 20160.8709677 with a remaining 1.3e-07.
