We look at the division of 79943670 by 660 
We want to figure out the number of times 79943670 can be divided by 660.

Advancing to step 1:
The number 660 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 660

Moving on to step 2:
79 divided by 660 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 660

Step 3:
The number 660 fits into 799 1 times, leaving a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 660 from 799 to get 139.
Include the next digit (4) from the dividend after 139, then repeat: 1394 / 660

Advancing to step 4:
When dividing 1394 by 660, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1320 from 1394, we get 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 660

On to step 5:
The number 660 fits into 743 1 times, leaving a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 660 away from 743, we end up with 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 660

Going ahead to step 6:
When dividing 836 by 660, we get 1 with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 1211.0
Subtracting 660 from 836 leaves us with 176.
Include the next digit (7) from the dividend after 176, then repeat: 1767 / 660

On to step 7:
660 goes into 1767 2 times with a remainder of 447.
Put 2 as the next digit of the answer. 
Result so far: 12112.0
If we take 1320 away from 1767, we end up with 447.
Fetch the next digit (0) from the dividend, attach it to 447 and continue: 4470 / 660

Going ahead to step 8:
When dividing 4470 by 660, we get 6 with a remainder of 510.
Put 6 as the next digit of the answer. 
Result so far: 121126.0
Subtract 3960 from 4470 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 9:
If we divide 5100 by 660, we get 7 and a remainder of 480.
Record the quotient 7 as the next digit in the result. 
Result so far: 121126.7
If we subtract 4620 from 5100, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 10:
660 goes into 4800 7 times with a remainder of 180.
Record the quotient 7 as the next digit in the result. 
Result so far: 121126.77
If we subtract 4620 from 4800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 121126.77, with a leftover of 0.18.
