We're dividing 637229 by 31 
We want to divide 637229 by 31.

Let's proceed to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 31

Moving on to step 2:
The number 31 fits into 63 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 62 from 63.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 31

Let's proceed to step 3:
When dividing 17 by 31, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 17 after subtracting 0 from 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 31

On to step 4:
31 goes into 172 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 205.0
If we take 155 away from 172, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 31

Advancing to step 5:
When dividing 172 by 31, we get 5 with a remainder of 17.
The next digit of our result is 5. 
Result so far: 2055.0
If we take 155 away from 172, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 31

Advancing to step 6:
The number 31 fits into 179 5 times, leaving a remainder of 24.
The next digit of our result is 5. 
Result so far: 20555.0
The remainder is 24 after subtracting 155 from 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
240 divided by 31 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 20555.7
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
When dividing 230 by 31, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 20555.77
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 20555.77, with a leftover of 0.013.
