We look at the division of 89124 by 12 
Let's see how many times 12 fits into 89124.

Let's proceed to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 12

On to step 2:
When dividing 89 by 12, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 84 from 89 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Step 3:
12 goes into 51 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
If we subtract 48 from 51, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 12

Advancing to step 4:
12 can be fit into 32 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 742.0
If we take 24 away from 32, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

Going ahead to step 5:
The number 12 fits into 84 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7427.0
Subtract 84 from 84 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.

Step 6:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7427.0
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.

Step 7:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7427.0
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.

Our division results in 7427.0 with a remaining 0.0.
