We're dividing 511341 by 66 
The aim is to understand the frequency of 66 in 511341.

Going ahead to step 1:
66 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 66

Let's proceed to step 2:
66 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 66

Advancing to step 3:
511 divided by 66 is 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 49 after subtracting 462 from 511.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 66

Let's proceed to step 4:
When dividing 493 by 66, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 462 from 493, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 66

On to step 5:
66 can be fit into 314 4 times, resulting in a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 774.0
If we subtract 264 from 314, we get 50.
Append the next digit (1) from the dividend to 50 and continue with: 501 / 66

On to step 6:
66 can be fit into 501 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7747.0
If we take 462 away from 501, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
390 divided by 66 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 7747.5
Subtract 330 from 390 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.

Going ahead to step 8:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 7747.59
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 9:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7747.59
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.

Step 10:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 7747.5909
If we subtract 594 from 600, we 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.

Going ahead to step 11:
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: 7747.5909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
600 divided by 66 is 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 7747.590909
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.

Moving on to step 13:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7747.590909
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.

Let's proceed to step 14:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 7747.59090909
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.

After the division, we end up with 7747.59090909 and a remainder of 6e-09.
