We look at the division of 79921239 by 852 
We want to figure out the number of times 79921239 can be divided by 852.

Let's proceed to step 1:
852 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 852

Step 2:
852 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 852

Step 3:
If we divide 799 by 852, we get 0 and a remainder of 799.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 799 leaves us with 799.
Take the next digit (2) from the dividend and append it to 799, then repeat: 7992 / 852

Moving on to step 4:
7992 divided by 852 is 9 with a remainder of 324.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7668 from 7992 leaves us with 324.
Fetch the next digit (1) from the dividend, attach it to 324 and continue: 3241 / 852

Moving on to step 5:
3241 divided by 852 is 3 with a remainder of 685.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtract 2556 from 3241 to get 685.
Fetch the next digit (2) from the dividend, attach it to 685 and continue: 6852 / 852

Advancing to step 6:
6852 divided by 852 is 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 938.0
Deduct 6816 from 6852 and we're left with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 852

Going ahead to step 7:
The number 852 fits into 363 0 times, leaving a remainder of 363.
The number 0 becomes the next digit in our result. 
Result so far: 9380.0
Subtracting 0 from 363 leaves us with 363.
Include the next digit (9) from the dividend after 363, then repeat: 3639 / 852

Step 8:
The number 852 fits into 3639 4 times, leaving a remainder of 231.
Use 4 as the next digit of our solution. 
Result so far: 93804.0
If we take 3408 away from 3639, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
2310 divided by 852 is 2 with a remainder of 606.
Write down 2 as next digit of the result. 
Result so far: 93804.2
Deduct 1704 from 2310 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 10:
6060 divided by 852 is 7 with a remainder of 96.
The next digit of our result is 7. 
Result so far: 93804.27
Deduct 5964 from 6060 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
When dividing 960 by 852, we get 1 with a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 93804.271
Subtract 852 from 960 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 12:
852 can be fit into 1080 1 times, resulting in a remainder of 228.
Put 1 as the next digit of the answer. 
Result so far: 93804.2711
The remainder is 228 after subtracting 852 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 93804.2711 and a remainder of 0.00228.
