We look at the division of 621285 by 31 
We want to figure out the number of times 621285 can be divided by 31.

Let's proceed to step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 31

Going ahead to step 2:
62 divided by 31 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 62 from 62, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 31

Advancing to step 3:
When dividing 1 by 31, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 31

On to step 4:
The number 31 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 12, we end up with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 31

Step 5:
If we divide 128 by 31, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 2004.0
Deduct 124 from 128 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 31

Moving on to step 6:
The number 31 fits into 45 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 20041.0
The remainder is 14 after subtracting 31 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 31 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 20041.4
The remainder is 16 after subtracting 124 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 31 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 20041.45
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
31 goes into 50 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 20041.451
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
If we divide 190 by 31, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 20041.4516
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 31, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 20041.45161
Subtracting 31 from 40 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 20041.451612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 20041.4516129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20041.4516129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 20041.4516129 with a balance of 1e-08.
