We look at the division of 20236079 by 852 
Let's see how many times 852 fits into 20236079.

Moving on to step 1:
When dividing 2 by 852, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 852

Step 2:
When dividing 20 by 852, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 852

Advancing to step 3:
202 divided by 852 is 0 with a remainder of 202.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 202 after subtracting 0 from 202.
Include the next digit (3) from the dividend after 202, then repeat: 2023 / 852

Advancing to step 4:
2023 divided by 852 is 2 with a remainder of 319.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1704 from 2023 to get 319.
Include the next digit (6) from the dividend after 319, then repeat: 3196 / 852

Advancing to step 5:
3196 divided by 852 is 3 with a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 2556 from 3196, we get 640.
Append the next digit (0) from the dividend to 640 and continue with: 6400 / 852

Moving on to step 6:
When dividing 6400 by 852, we get 7 with a remainder of 436.
Put 7 as the next digit of the answer. 
Result so far: 237.0
Subtracting 5964 from 6400 leaves us with 436.
Take the next digit (7) from the dividend and append it to 436, then repeat: 4367 / 852

Advancing to step 7:
If we divide 4367 by 852, we get 5 and a remainder of 107.
Record the quotient 5 as the next digit in the result. 
Result so far: 2375.0
If we subtract 4260 from 4367, we get 107.
Fetch the next digit (9) from the dividend, attach it to 107 and continue: 1079 / 852

Step 8:
If we divide 1079 by 852, we get 1 and a remainder of 227.
The next digit of our result is 1. 
Result so far: 23751.0
Deduct 852 from 1079 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 9:
If we divide 2270 by 852, we get 2 and a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 23751.2
Subtracting 1704 from 2270 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 10:
When dividing 5660 by 852, we get 6 with a remainder of 548.
Record the quotient 6 as the next digit in the result. 
Result so far: 23751.26
Subtract 5112 from 5660 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 11:
852 goes into 5480 6 times with a remainder of 368.
Put 6 as the next digit of the answer. 
Result so far: 23751.266
Subtracting 5112 from 5480 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The quotient of the division is 23751.266, and the remainder is 0.0368.
