We look at the division of 984123 by 12 
We want to divide 984123 by 12.

On to step 1:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

On to step 2:
When dividing 98 by 12, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 96 away from 98, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

On to step 3:
The number 12 fits into 24 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 82.0
If we take 24 away from 24, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

On to step 4:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 12

Going ahead to step 5:
When dividing 12 by 12, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 8201.0
If we subtract 12 from 12, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 12

Moving on to step 6:
If we divide 3 by 12, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 82010.0
If we subtract 0 from 3, 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.

Moving on to step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 82010.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

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: 82010.25
If we take 60 away from 60, we end up 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.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 82010.25
Deduct 0 from 0 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.

Going ahead to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 82010.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 82010.25 and a remainder of 0.0.
