We look at the division of 621300 by 36 
Our goal is to divide 621300 by 36.

On to step 1:
36 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 36

On to step 2:
36 goes into 62 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 36 from 62 leaves us with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 36

On to step 3:
36 goes into 261 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 9 after subtracting 252 from 261.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 36

Moving on to step 4:
93 divided by 36 is 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we subtract 72 from 93, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 36

On to step 5:
210 divided by 36 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1725.0
Deduct 180 from 210 and we're left with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 36

Going ahead to step 6:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 17258.0
The remainder is 12 after subtracting 288 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 36 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 17258.3
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.

Moving on to step 8:
120 divided by 36 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 17258.33
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.

The final outcome is 17258.33, with a leftover of 0.012.
