We look at the division of 636266 by 31 
We're looking to find how many times 31 goes into 636266.

Moving on to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 31

Moving on to step 2:
If we divide 63 by 31, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 62 from 63 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 31

On to step 3:
31 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 16, we end up with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 31

Advancing to step 4:
31 can be fit into 162 5 times, resulting in a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtracting 155 from 162 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 31

On to step 5:
The number 31 fits into 76 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2052.0
Subtracting 62 from 76 leaves us with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 31

Advancing to step 6:
31 goes into 146 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 20524.0
Subtracting 124 from 146 leaves us 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.

Let's proceed to step 7:
If we divide 220 by 31, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 20524.7
If we subtract 217 from 220, we 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.

Let's proceed to step 8:
When dividing 30 by 31, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 20524.7
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
300 divided by 31 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 20524.709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 20524.7096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 31, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 20524.70967
If we subtract 217 from 240, we 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.

Going ahead to step 12:
If we divide 230 by 31, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 20524.709677
Deduct 217 from 230 and we're left with 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 result is 20524.709677 with a remainder of 1.3e-06.
