837939 ÷ 12 
Our goal is to divide 837939 by 12.

Let's proceed to step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Advancing to step 2:
83 divided by 12 is 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
If we take 72 away from 83, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 12

Step 3:
The number 12 fits into 117 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtract 108 from 117 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

On to step 4:
99 divided by 12 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 698.0
If we subtract 96 from 99, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Advancing to step 5:
If we divide 33 by 12, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 6982.0
Deduct 24 from 33 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Let's proceed to step 6:
When dividing 99 by 12, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 69828.0
If we subtract 96 from 99, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 69828.2
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 69828.25
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 69828.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 69828.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 69828.25, with a leftover of 0.0.
