We look at the division of 10825324 by 660 
The aim is to understand the frequency of 660 in 10825324.

Moving on to step 1:
660 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 660

Going ahead to step 2:
660 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 660

Going ahead to step 3:
The number 660 fits into 108 0 times, leaving a remainder of 108.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 108 after subtracting 0 from 108.
Grab the next digit (2) from the dividend, add it to 108, then carry on: 1082 / 660

Advancing to step 4:
When dividing 1082 by 660, we get 1 with a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 422 after subtracting 660 from 1082.
Fetch the next digit (5) from the dividend, attach it to 422 and continue: 4225 / 660

Going ahead to step 5:
660 goes into 4225 6 times with a remainder of 265.
The next digit of our result is 6. 
Result so far: 16.0
If we take 3960 away from 4225, we end up with 265.
Fetch the next digit (3) from the dividend, attach it to 265 and continue: 2653 / 660

Going ahead to step 6:
When dividing 2653 by 660, we get 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 2640 from 2653 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 660

On to step 7:
132 divided by 660 is 0 with a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 1640.0
If we subtract 0 from 132, we get 132.
Append the next digit (4) from the dividend to 132 and continue with: 1324 / 660

Advancing to step 8:
The number 660 fits into 1324 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 16402.0
Deduct 1320 from 1324 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 660 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 16402.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 660 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 16402.0
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 16402.0, with a leftover of 0.4.
