88877 ÷ 66 
The aim is to understand the frequency of 66 in 88877.

Moving on to step 1:
The number 66 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 66

Let's proceed to step 2:
When dividing 88 by 66, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 66 away from 88, we end up with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 66

Moving on to step 3:
228 divided by 66 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 198 from 228 leaves us with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 66

Going ahead to step 4:
66 goes into 307 4 times with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 134.0
Subtracting 264 from 307 leaves us with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 66

Let's proceed to step 5:
When dividing 437 by 66, we get 6 with a remainder of 41.
The number 6 becomes the next digit in our result. 
Result so far: 1346.0
The remainder is 41 after subtracting 396 from 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 6:
When dividing 410 by 66, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1346.6
If we take 396 away from 410, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 66, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1346.62
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1346.621
Subtract 66 from 80 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1346.6212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 66, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1346.62121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 66 fits into 140 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1346.621212
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1346.6212121
If we subtract 66 from 80, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
140 divided by 66 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1346.62121212
Subtracting 132 from 140 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1346.62121212 and a remainder of 8e-09.
