Let's divide 782109 by 12
Our goal is to divide 782109 by 12.

On to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 12

Going ahead to step 2:
When dividing 78 by 12, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 6 after subtracting 72 from 78.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 12

Advancing to step 3:
62 divided by 12 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we subtract 60 from 62, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 12

Advancing to step 4:
21 divided by 12 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 651.0
If we subtract 12 from 21, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

Step 5:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 6517.0
Subtracting 84 from 90 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 12

Advancing to step 6:
When dividing 69 by 12, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 65175.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 65175.7
If we subtract 84 from 90, 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.

Advancing to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 65175.75
Deduct 60 from 60 and we're left 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.

On to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 65175.75
If we subtract 0 from 0, we 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.

Going ahead to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 65175.75
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.

The final outcome is 65175.75, with a leftover of 0.0.
