922915 ÷ 66 
The aim is to understand the frequency of 66 in 922915.

Step 1:
66 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 66

On to step 2:
66 goes into 92 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 66 from 92 leaves us with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 66

Moving on to step 3:
When dividing 262 by 66, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 198 away from 262, we end up with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 66

Moving on to step 4:
66 goes into 649 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtracting 594 from 649 leaves us with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 66

Let's proceed to step 5:
66 goes into 551 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 1398.0
Subtracting 528 from 551 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 66

Let's proceed to step 6:
66 goes into 235 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 13983.0
Subtract 198 from 235 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
66 can be fit into 370 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 13983.5
The remainder is 40 after subtracting 330 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 66 fits into 400 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 13983.56
If we take 396 away from 400, we end up 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.

On to step 9:
When dividing 40 by 66, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 13983.56
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 66 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13983.5606
Deduct 396 from 400 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.

Advancing to step 11:
When dividing 40 by 66, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13983.5606
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
The number 66 fits into 400 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 13983.560606
If we take 396 away from 400, we end up 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.

Let's proceed to step 13:
When dividing 40 by 66, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13983.560606
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.

Moving on to step 14:
400 divided by 66 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13983.56060606
If we take 396 away from 400, we end up 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.

After the division, we end up with 13983.56060606 and a remainder of 4e-09.
