We look at the division of 64824122 by 660 
The aim is to understand the frequency of 660 in 64824122.

Advancing to step 1:
660 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 660

Let's proceed to step 2:
When dividing 64 by 660, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 660

Moving on to step 3:
If we divide 648 by 660, we get 0 and a remainder of 648.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 648, we end up with 648.
Take the next digit (2) from the dividend and append it to 648, then repeat: 6482 / 660

Let's proceed to step 4:
6482 divided by 660 is 9 with a remainder of 542.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 5940 from 6482 and we're left with 542.
Bring next digit (4) of the dividend behind the 542 and repeat the process: 5424 / 660

On to step 5:
5424 divided by 660 is 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Deduct 5280 from 5424 and we're left with 144.
Take the next digit (1) from the dividend and append it to 144, then repeat: 1441 / 660

Moving on to step 6:
When dividing 1441 by 660, we get 2 with a remainder of 121.
Use 2 as the next digit of our solution. 
Result so far: 982.0
The remainder is 121 after subtracting 1320 from 1441.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 660

Step 7:
1212 divided by 660 is 1 with a remainder of 552.
The next digit of our result is 1. 
Result so far: 9821.0
Subtract 660 from 1212 to get 552.
Fetch the next digit (2) from the dividend, attach it to 552 and continue: 5522 / 660

Going ahead to step 8:
5522 divided by 660 is 8 with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 98218.0
If we subtract 5280 from 5522, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 9:
2420 divided by 660 is 3 with a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 98218.3
If we subtract 1980 from 2420, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
660 goes into 4400 6 times with a remainder of 440.
Put 6 as the next digit of the answer. 
Result so far: 98218.36
Subtract 3960 from 4400 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 11:
If we divide 4400 by 660, we get 6 and a remainder of 440.
The next digit of our result is 6. 
Result so far: 98218.366
If we subtract 3960 from 4400, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 98218.366 with a remaining 0.044.
