We divide 335268 by 66
The aim is to understand the frequency of 66 in 335268.

Step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 66

On to step 2:
If we divide 33 by 66, we get 0 and a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 66

Going ahead to step 3:
The number 66 fits into 335 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 330 from 335 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 66

Advancing to step 4:
If we divide 52 by 66, we get 0 and a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we take 0 away from 52, we end up with 52.
Take the next digit (6) from the dividend and append it to 52, then repeat: 526 / 66

Going ahead to step 5:
66 goes into 526 7 times with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
If we take 462 away from 526, we end up with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 66

Step 6:
If we divide 648 by 66, we get 9 and a remainder of 54.
The next digit of our result is 9. 
Result so far: 5079.0
Subtract 594 from 648 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5079.8
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
When dividing 120 by 66, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 5079.81
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
When dividing 540 by 66, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 5079.818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
When dividing 120 by 66, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 5079.8181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
When dividing 540 by 66, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5079.81818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
120 divided by 66 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 5079.818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 5079.8181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
66 goes into 120 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 5079.81818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 5079.81818181, and the remainder is 5.4e-08.
