We divide 636155 by 31
We're looking to find how many times 31 goes into 636155.

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
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 31

Let's proceed to step 2:
31 can be fit into 63 2 times, resulting in 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.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 31

On to step 3:
31 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 31

On to step 4:
If we divide 161 by 31, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Subtract 155 from 161 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 31

Let's proceed to step 5:
If we divide 65 by 31, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2052.0
The remainder is 3 after subtracting 62 from 65.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 31

Step 6:
The number 31 fits into 35 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 20521.0
Deduct 31 from 35 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.

On to step 7:
40 divided by 31 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 20521.1
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
When dividing 90 by 31, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 20521.12
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
31 goes into 280 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 20521.129
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 20521.129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 20521.12903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
70 divided by 31 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 20521.129032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 31 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 20521.1290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 20521.1290322, and the remainder is 1.8e-07.
