991419 ÷ 12 
We're looking to find how many times 12 goes into 991419.

Advancing to step 1:
The number 12 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 12

On to step 2:
12 goes into 99 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 96 from 99 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Advancing to step 3:
If we divide 31 by 12, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 24 away from 31, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

Step 4:
12 can be fit into 74 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 826.0
Deduct 72 from 74 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Advancing to step 5:
The number 12 fits into 21 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 8261.0
Subtracting 12 from 21 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

Let's proceed to step 6:
12 can be fit into 99 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 82618.0
Subtracting 96 from 99 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 82618.2
Deduct 24 from 30 and we're left 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.

On to step 8:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 82618.25
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.

Going ahead to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 82618.25
Subtracting 0 from 0 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.

Going ahead to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 82618.25
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 quotient of the division is 82618.25, and the remainder is 0.0.
