We look at the division of 989297 by 66 
The aim is to understand the frequency of 66 in 989297.

Advancing to step 1:
66 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 66

On to step 2:
The number 66 fits into 98 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 66 from 98 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 66

Step 3:
If we divide 329 by 66, we get 4 and a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 65 after subtracting 264 from 329.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 66

Going ahead to step 4:
When dividing 652 by 66, we get 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 594 from 652 and we're left with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 66

Step 5:
If we divide 589 by 66, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 1498.0
The remainder is 61 after subtracting 528 from 589.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 66

Let's proceed to step 6:
The number 66 fits into 617 9 times, leaving a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 14989.0
Subtracting 594 from 617 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
66 can be fit into 230 3 times, resulting in a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 14989.3
Subtracting 198 from 230 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 14989.34
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
66 goes into 560 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 14989.348
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 14989.3484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 66, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 14989.34848
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
When dividing 320 by 66, we get 4 with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 14989.348484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
560 divided by 66 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 14989.3484848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
The number 66 fits into 320 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 14989.34848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 14989.34848484 with a remainder of 5.6e-08.
