Let's divide 879172 by 12
We're looking to find how many times 12 goes into 879172.

Let's proceed to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 12

Going ahead to step 2:
12 goes into 87 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 84 away from 87, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 12

Let's proceed to step 3:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 36 from 39 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 12

On to step 4:
The number 12 fits into 31 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 732.0
Subtracting 24 from 31 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 12

On to step 5:
If we divide 77 by 12, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 7326.0
The remainder is 5 after subtracting 72 from 77.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Advancing to step 6:
52 divided by 12 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 73264.0
If we subtract 48 from 52, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 73264.3
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 73264.33
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 73264.33, with a leftover of 0.004.
