We're dividing 889400 by 12 
We're looking to find how many times 12 goes into 889400.

Advancing to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 12

Going ahead to step 2:
The number 12 fits into 88 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 84 from 88 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 12

Advancing to step 3:
If we divide 49 by 12, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 48 from 49 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 12

On to step 4:
12 goes into 14 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
If we subtract 12 from 14, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Going ahead to step 5:
If we divide 20 by 12, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 7411.0
Deduct 12 from 20 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 12

Going ahead to step 6:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 74116.0
Subtracting 72 from 80 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.

On to step 7:
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: 74116.6
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.

Moving on to step 8:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 74116.66
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.

Our division results in 74116.66 with a remaining 0.008.
