837128 ÷ 12 
We want to figure out the number of times 837128 can be divided by 12.

Going ahead to step 1:
8 divided by 12 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 12

Step 2:
83 divided by 12 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 72 away from 83, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 12

Let's proceed to step 3:
If we divide 117 by 12, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 108 from 117 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

Going ahead to step 4:
If we divide 91 by 12, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 697.0
Subtract 84 from 91 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Step 5:
72 divided by 12 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6976.0
The remainder is 0 after subtracting 72 from 72.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 12

Step 6:
8 divided by 12 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 69760.0
The remainder is 8 after subtracting 0 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 69760.6
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.

On to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 69760.66
Deduct 72 from 80 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.

The final outcome is 69760.66, with a leftover of 0.008.
