630610 ÷ 31 
We want to divide 630610 by 31.

Step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 31

On to step 2:
31 goes into 63 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 62 from 63.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 31

Moving on to step 3:
31 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 31

Let's proceed to step 4:
The number 31 fits into 106 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 203.0
Subtract 93 from 106 to get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 31

Moving on to step 5:
31 goes into 131 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 2034.0
If we take 124 away from 131, we end up with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 31

On to step 6:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 20342.0
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 31, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 20342.2
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 31 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 20342.25
Subtract 155 from 180 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 31, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 20342.258
The remainder is 2 after subtracting 248 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
31 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 20342.258
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
31 goes into 200 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 20342.25806
If we take 186 away from 200, we end up 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.

Going ahead to step 12:
When dividing 140 by 31, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 20342.258064
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.

Step 13:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 20342.2580645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 31, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 20342.25806451
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 20342.25806451 with a balance of 1.9e-08.
