207369 ÷ 66 
The aim is to understand the frequency of 66 in 207369.

Advancing to step 1:
2 divided by 66 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 66

Advancing to step 2:
20 divided by 66 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 66

Let's proceed to step 3:
When dividing 207 by 66, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 198 from 207 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 66

Moving on to step 4:
66 goes into 93 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 66 from 93, we get 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 66

Step 5:
The number 66 fits into 276 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 314.0
Subtracting 264 from 276 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 66

On to step 6:
129 divided by 66 is 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 3141.0
Subtract 66 from 129 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
66 goes into 630 9 times with a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 3141.9
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
When dividing 360 by 66, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3141.95
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3141.954
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
66 goes into 360 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 3141.9545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 3141.95454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3141.954545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 3141.9545454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3141.95454545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 3141.95454545 with a remainder of 3e-08.
