We divide 270521 by 66
The aim is to understand the frequency of 66 in 270521.

Let's proceed to step 1:
2 divided by 66 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 66

Moving on to step 2:
66 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 66

On to step 3:
270 divided by 66 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 264 away from 270, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 66

Let's proceed to step 4:
66 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 66

Going ahead to step 5:
66 can be fit into 652 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 409.0
Deduct 594 from 652 and we're left with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 66

Advancing to step 6:
The number 66 fits into 581 8 times, leaving a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 4098.0
If we take 528 away from 581, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
When dividing 530 by 66, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4098.8
If we subtract 528 from 530, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 66, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4098.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 66, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 4098.803
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
20 divided by 66 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4098.803
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 4098.80303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 66, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4098.80303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
66 can be fit into 200 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 4098.8030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
If we divide 20 by 66, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4098.8030303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 4098.8030303 with a remainder of 2e-08.
