161298 divided by 66 
The aim is to understand the frequency of 66 in 161298.

On to step 1:
66 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 66

Let's proceed to step 2:
If we divide 16 by 66, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 66

On to step 3:
161 divided by 66 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 132 from 161 to get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 66

Going ahead to step 4:
66 goes into 292 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 264 from 292 to get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 66

Step 5:
When dividing 289 by 66, we get 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 244.0
Deduct 264 from 289 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 66

Advancing to step 6:
When dividing 258 by 66, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 2443.0
If we subtract 198 from 258, we get 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 7:
If we divide 600 by 66, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 2443.9
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.

Step 8:
60 divided by 66 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 2443.9
If we take 0 away from 60, we end up 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 9:
600 divided by 66 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 2443.909
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.

Going ahead to step 10:
When dividing 60 by 66, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 2443.909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 2443.90909
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.

Moving on to step 12:
The number 66 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 2443.90909
If we take 0 away from 60, we end up 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.

Moving on to step 13:
If we divide 600 by 66, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 2443.9090909
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.

Going ahead to step 14:
66 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2443.9090909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 2443.9090909, with a leftover of 6e-08.
