We're dividing 11979 by 45 
We're looking to find how many times 45 goes into 11979.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 45

Step 2:
11 divided by 45 is 0 with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 45

On to step 3:
119 divided by 45 is 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 90 away from 119, we end up with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 45

On to step 4:
If we divide 297 by 45, we get 6 and a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we subtract 270 from 297, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 45

Let's proceed to step 5:
The number 45 fits into 279 6 times, leaving a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 266.0
Subtract 270 from 279 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
When dividing 90 by 45, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 266.2
If we subtract 90 from 90, 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.

Advancing to step 7:
45 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 266.2
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 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 266.2
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.

The quotient of the division is 266.2, and the remainder is 0.0.
