Let's divide 103499 by 12
Let's see how many times 12 fits into 103499.

Going ahead to step 1:
1 divided by 12 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 12

Moving on to step 2:
10 divided by 12 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 12

Advancing to step 3:
When dividing 103 by 12, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 96 from 103, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Moving on to step 4:
12 goes into 74 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 86.0
If we take 72 away from 74, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 12

Advancing to step 5:
The number 12 fits into 29 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 862.0
If we subtract 24 from 29, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 12

On to step 6:
12 can be fit into 59 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 8624.0
Subtract 48 from 59 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
12 can be fit into 110 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8624.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 8624.91
Subtracting 12 from 20 leaves us 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.

Advancing to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 8624.916
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.

Let's proceed to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 8624.9166
Subtract 72 from 80 to 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.

After the division, we end up with 8624.9166 and a remainder of 8e-05.
