We're dividing 642891 by 36 
Our goal is to divide 642891 by 36.

On to step 1:
36 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 36

Moving on to step 2:
36 can be fit into 64 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 36 from 64 to get 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 36

On to step 3:
When dividing 282 by 36, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtract 252 from 282 to get 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 36

Let's proceed to step 4:
The number 36 fits into 308 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 20 after subtracting 288 from 308.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 36

Step 5:
36 goes into 209 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 1785.0
Deduct 180 from 209 and we're left with 29.
Include the next digit (1) from the dividend after 29, then repeat: 291 / 36

Going ahead to step 6:
291 divided by 36 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 17858.0
Subtract 288 from 291 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.

Advancing to step 7:
36 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 17858.0
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.

Moving on to step 8:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 17858.08
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 36 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 17858.083
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 36, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 17858.0833
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 17858.0833, and the remainder is 0.00012.
