We're dividing 98499780 by 12 
We want to divide 98499780 by 12.

Advancing to step 1:
When dividing 9 by 12, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 12

Step 2:
When dividing 98 by 12, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 2 after subtracting 96 from 98.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Moving 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
Subtracting 24 from 24 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

On to step 4:
If we divide 9 by 12, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 820.0
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

Advancing to step 5:
If we divide 99 by 12, we get 8 and a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8208.0
Deduct 96 from 99 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 12

Advancing to step 6:
When dividing 37 by 12, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 82083.0
Deduct 36 from 37 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 12

Going ahead to step 7:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 820831.0
Subtracting 12 from 18 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 12

Going ahead to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8208315.0
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.

Going ahead to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8208315.0
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:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8208315.0
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.

The quotient of the division is 8208315.0, and the remainder is 0.0.
