874379 ÷ 12 
We're looking to find how many times 12 goes into 874379.

Advancing to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 12

Going ahead to step 2:
The number 12 fits into 87 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 84 from 87 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

Moving on to step 3:
34 divided by 12 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 24 from 34, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Step 4:
103 divided by 12 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 728.0
Deduct 96 from 103 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 12

Going ahead to step 5:
12 can be fit into 77 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 7286.0
If we subtract 72 from 77, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

On to step 6:
The number 12 fits into 59 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 72864.0
If we take 48 away from 59, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
12 goes into 110 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 72864.9
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 72864.91
Deduct 12 from 20 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 12 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 72864.916
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 72864.9166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 72864.9166, with a leftover of 8e-05.
