642999 ÷ 36 
Our goal is to divide 642999 by 36.

Let's proceed to step 1:
6 divided by 36 is 0 with 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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 36

Advancing to step 2:
If we divide 64 by 36, we get 1 and 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.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 36

Going ahead to step 3:
36 can be fit into 282 7 times, resulting in a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 30 after subtracting 252 from 282.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 36

Going ahead to step 4:
The number 36 fits into 309 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
The remainder is 21 after subtracting 288 from 309.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 36

On to step 5:
36 can be fit into 219 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1786.0
Subtracting 216 from 219 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 36

Going ahead to step 6:
36 can be fit into 39 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 17861.0
If we subtract 36 from 39, 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.

Going ahead to step 7:
36 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 17861.0
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.

On to step 8:
36 can be fit into 300 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 17861.08
Subtracting 288 from 300 leaves us 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.

On to step 9:
If we divide 120 by 36, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 17861.083
If we take 108 away from 120, we end up 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.

On to step 10:
When dividing 120 by 36, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 17861.0833
Deduct 108 from 120 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.

The quotient of the division is 17861.0833, and the remainder is 0.00012.
