636018 ÷ 31 
We want to divide 636018 by 31.

Moving on to step 1:
The number 31 fits into 6 0 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 31

Moving on to step 2:
When dividing 63 by 31, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 63 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 31

Step 3:
16 divided by 31 is 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 16 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 31

Going ahead to step 4:
When dividing 160 by 31, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 205.0
If we subtract 155 from 160, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 31

On to step 5:
31 can be fit into 51 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 2051.0
If we take 31 away from 51, we end up with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 31

Let's proceed to step 6:
The number 31 fits into 208 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 20516.0
The remainder is 22 after subtracting 186 from 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 31, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 20516.7
Subtract 217 from 220 to 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.

On to step 8:
If we divide 30 by 31, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 20516.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 31 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 20516.709
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.

Let's proceed to step 10:
If we divide 210 by 31, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 20516.7096
If we take 186 away from 210, we end up 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.

On to step 11:
If we divide 240 by 31, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 20516.70967
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 12:
31 goes into 230 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 20516.709677
If we take 217 away from 230, we end up 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 20516.709677 with a remainder of 1.3e-06.
