We're dividing 639942 by 36 
Our goal is to divide 639942 by 36.

Going ahead to step 1:
6 divided by 36 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 36

Moving on to step 2:
The number 36 fits into 63 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 36 from 63 to get 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 36

Advancing to step 3:
36 goes into 279 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 252 from 279 leaves us with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 36

Going ahead to step 4:
The number 36 fits into 279 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Deduct 252 from 279 and we're left with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 36

Going ahead to step 5:
The number 36 fits into 274 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 1777.0
If we subtract 252 from 274, we get 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 36

Advancing to step 6:
When dividing 222 by 36, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 17776.0
If we subtract 216 from 222, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 36, we get 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 17776.1
The remainder is 24 after subtracting 36 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
36 goes into 240 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 17776.16
Deduct 216 from 240 and we're left 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 9:
36 can be fit into 240 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 17776.166
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 17776.166 with a remaining 0.0024.
