Let's divide 880402 by 12
We're looking to find how many times 12 goes into 880402.

Let's proceed to step 1:
12 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 12

On to step 2:
88 divided by 12 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 84 from 88 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 12

On to step 3:
If we divide 40 by 12, we get 3 and a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
The remainder is 4 after subtracting 36 from 40.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 12

Going ahead to step 4:
If we divide 44 by 12, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 733.0
Subtract 36 from 44 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

Let's proceed to step 5:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 7336.0
Subtracting 72 from 80 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 12

Advancing to step 6:
The number 12 fits into 82 6 times, leaving a remainder of 10.
The next digit of our result is 6. 
Result so far: 73366.0
Deduct 72 from 82 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 73366.8
If we subtract 96 from 100, 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 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 73366.83
If we take 36 away from 40, we end up 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.

Going ahead to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 73366.833
If we take 36 away from 40, we end up 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 73366.833, with a leftover of 0.0004.
