630372 divided by 31 
Let's see how many times 31 fits into 630372.

Step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 31

Advancing to step 2:
The number 31 fits into 63 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 62 from 63, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 31

Going ahead to step 3:
10 divided by 31 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 10 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 31

Moving on to step 4:
103 divided by 31 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 203.0
Deduct 93 from 103 and we're left with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 31

On to step 5:
31 goes into 107 3 times with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 2033.0
The remainder is 14 after subtracting 93 from 107.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 31

Going ahead to step 6:
When dividing 142 by 31, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 20334.0
The remainder is 18 after subtracting 124 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 31, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 20334.5
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
31 can be fit into 250 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 20334.58
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
If we divide 20 by 31, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 20334.58
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
31 goes into 200 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 20334.5806
Deduct 186 from 200 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
31 can be fit into 140 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 20334.58064
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 20334.580645
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.

On to step 13:
If we divide 50 by 31, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 20334.5806451
Subtracting 31 from 50 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
When dividing 190 by 31, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 20334.58064516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 20334.58064516, with a leftover of 4e-09.
