We look at the division of 891519 by 12 
We want to figure out the number of times 891519 can be divided by 12.

On to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 12

Let's proceed to step 2:
When dividing 89 by 12, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 5 after subtracting 84 from 89.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 12

Moving on to step 3:
If we divide 51 by 12, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 48 from 51 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Moving on to step 4:
The number 12 fits into 35 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 742.0
Subtracting 24 from 35 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 12

On to step 5:
If we divide 111 by 12, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 7429.0
If we subtract 108 from 111, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

On to step 6:
If we divide 39 by 12, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 74293.0
If we subtract 36 from 39, 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.

Step 7:
12 goes into 30 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 74293.2
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.

Advancing to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 74293.25
Subtracting 60 from 60 leaves us 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.

Let's proceed to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74293.25
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.

Moving on to step 10:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 74293.25
If we take 0 away from 0, 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.

The final outcome is 74293.25, with a leftover of 0.0.
