We look at the division of 824172 by 79 
We want to figure out the number of times 824172 can be divided by 79.

Step 1:
79 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 79

On to step 2:
The number 79 fits into 82 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 79 away from 82, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 79

Moving on to step 3:
34 divided by 79 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 79

Going ahead to step 4:
341 divided by 79 is 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtracting 316 from 341 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 79

Moving on to step 5:
If we divide 257 by 79, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 1043.0
If we take 237 away from 257, we end up with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 79

Step 6:
The number 79 fits into 202 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 10432.0
If we take 158 away from 202, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
The number 79 fits into 440 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 10432.5
If we take 395 away from 440, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
When dividing 450 by 79, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 10432.55
Deduct 395 from 450 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 10432.55 and a remainder of 0.055.
