Let's divide 84288 by 66
The aim is to understand the frequency of 66 in 84288.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 66

On to step 2:
The number 66 fits into 84 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 84 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 66

Going ahead to step 3:
When dividing 182 by 66, we get 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 132 away from 182, we end up with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 66

Going ahead to step 4:
If we divide 508 by 66, we get 7 and a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 462 from 508 and we're left with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 66

Advancing to step 5:
66 goes into 468 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1277.0
If we take 462 away from 468, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 6:
60 divided by 66 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1277.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 66 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1277.09
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
66 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 1277.09
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 1277.0909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 66 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1277.0909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 66 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1277.090909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 66, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1277.090909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 1277.09090909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 1277.09090909 with a remainder of 6e-09.
