869798 ÷ 12 
We want to figure out the number of times 869798 can be divided by 12.

Moving on to step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 12

Advancing to step 2:
86 divided by 12 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 84 from 86 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 12

Moving on to step 3:
29 divided by 12 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtracting 24 from 29 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 12

On to step 4:
12 goes into 57 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 724.0
Deduct 48 from 57 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 12

Step 5:
When dividing 99 by 12, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 7248.0
If we subtract 96 from 99, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Advancing to step 6:
If we divide 38 by 12, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 72483.0
The remainder is 2 after subtracting 36 from 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 72483.1
If we subtract 12 from 20, 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.

Advancing to step 8:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 72483.16
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
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: 72483.166
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.

In conclusion, the division gives 72483.166 with a balance of 0.0008.
