59528036 divided by 660 
The aim is to understand the frequency of 660 in 59528036.

Moving on to step 1:
660 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 660

On to step 2:
660 goes into 59 0 times with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Bring next digit (5) of the dividend behind the 59 and repeat the process: 595 / 660

Let's proceed to step 3:
The number 660 fits into 595 0 times, leaving a remainder of 595.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 595 leaves us with 595.
Include the next digit (2) from the dividend after 595, then repeat: 5952 / 660

On to step 4:
660 can be fit into 5952 9 times, resulting in a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 12 after subtracting 5940 from 5952.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 660

Step 5:
660 can be fit into 128 0 times, resulting in a remainder of 128.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 128 and we're left with 128.
Append the next digit (0) from the dividend to 128 and continue with: 1280 / 660

Moving on to step 6:
If we divide 1280 by 660, we get 1 and a remainder of 620.
The number 1 becomes the next digit in our result. 
Result so far: 901.0
If we take 660 away from 1280, we end up with 620.
Fetch the next digit (3) from the dividend, attach it to 620 and continue: 6203 / 660

On to step 7:
The number 660 fits into 6203 9 times, leaving a remainder of 263.
The next digit of our result is 9. 
Result so far: 9019.0
The remainder is 263 after subtracting 5940 from 6203.
Include the next digit (6) from the dividend after 263, then repeat: 2636 / 660

Advancing to step 8:
The number 660 fits into 2636 3 times, leaving a remainder of 656.
Use 3 as the next digit of our solution. 
Result so far: 90193.0
If we subtract 1980 from 2636, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 9:
When dividing 6560 by 660, we get 9 with a remainder of 620.
Put 9 as the next digit of the answer. 
Result so far: 90193.9
The remainder is 620 after subtracting 5940 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
When dividing 6200 by 660, we get 9 with a remainder of 260.
The next digit of our result is 9. 
Result so far: 90193.99
Subtracting 5940 from 6200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 90193.99, with a leftover of 0.26.
