298215 divided by 66 
The aim is to understand the frequency of 66 in 298215.

Let's proceed to step 1:
66 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 66

Going ahead to step 2:
29 divided by 66 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 66

Advancing to step 3:
298 divided by 66 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 264 away from 298, we end up with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 66

On to step 4:
If we divide 342 by 66, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 330 away from 342, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 66

Moving on to step 5:
If we divide 121 by 66, we get 1 and a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 451.0
If we subtract 66 from 121, we get 55.
Grab the next digit (5) from the dividend, add it to 55, then carry on: 555 / 66

On to step 6:
The number 66 fits into 555 8 times, leaving a remainder of 27.
The next digit of our result is 8. 
Result so far: 4518.0
Subtract 528 from 555 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
If we divide 270 by 66, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4518.4
If we take 264 away from 270, 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.

Advancing to step 8:
If we divide 60 by 66, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4518.4
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 9:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4518.409
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.

Advancing to step 10:
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: 4518.409
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.

Let's proceed to step 11:
When dividing 600 by 66, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 4518.40909
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.

Step 12:
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: 4518.40909
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 13:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 4518.4090909
Subtract 594 from 600 to get 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 14:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 4518.4090909
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.

Our division results in 4518.4090909 with a remaining 6e-08.
