Let's divide 66479059 by 660
Our goal is to divide 66479059 by 660.

Advancing to step 1:
The number 660 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 660

Moving on to step 2:
660 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 660

Let's proceed to step 3:
664 divided by 660 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 660 from 664 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 660

On to step 4:
If we divide 47 by 660, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 47, we end up with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 660

Step 5:
479 divided by 660 is 0 with a remainder of 479.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 479 to get 479.
Take the next digit (0) from the dividend and append it to 479, then repeat: 4790 / 660

On to step 6:
660 can be fit into 4790 7 times, resulting in a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
If we subtract 4620 from 4790, we get 170.
Append the next digit (5) from the dividend to 170 and continue with: 1705 / 660

On to step 7:
If we divide 1705 by 660, we get 2 and a remainder of 385.
The number 2 becomes the next digit in our result. 
Result so far: 10072.0
Subtracting 1320 from 1705 leaves us with 385.
Bring next digit (9) of the dividend behind the 385 and repeat the process: 3859 / 660

Moving on to step 8:
660 can be fit into 3859 5 times, resulting in a remainder of 559.
Record the quotient 5 as the next digit in the result. 
Result so far: 100725.0
The remainder is 559 after subtracting 3300 from 3859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 9:
When dividing 5590 by 660, we get 8 with a remainder of 310.
Put 8 as the next digit of the answer. 
Result so far: 100725.8
The remainder is 310 after subtracting 5280 from 5590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
When dividing 3100 by 660, we get 4 with a remainder of 460.
The number 4 becomes the next digit in our result. 
Result so far: 100725.84
If we take 2640 away from 3100, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
If we divide 4600 by 660, we get 6 and a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 100725.846
If we subtract 3960 from 4600, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 12:
6400 divided by 660 is 9 with a remainder of 460.
Write down 9 as next digit of the result. 
Result so far: 100725.8469
The remainder is 460 after subtracting 5940 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 13:
4600 divided by 660 is 6 with a remainder of 640.
Write down 6 as next digit of the result. 
Result so far: 100725.84696
If we take 3960 away from 4600, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 14:
660 can be fit into 6400 9 times, resulting in a remainder of 460.
The next digit of our result is 9. 
Result so far: 100725.846969
The remainder is 460 after subtracting 5940 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 15:
4600 divided by 660 is 6 with a remainder of 640.
The number 6 becomes the next digit in our result. 
Result so far: 100725.8469696
Subtracting 3960 from 4600 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 16:
When dividing 6400 by 660, we get 9 with a remainder of 460.
Write down 9 as next digit of the result. 
Result so far: 100725.84696969
If we subtract 5940 from 6400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

In conclusion, the division gives 100725.84696969 with a balance of 4.6e-07.
