We're dividing 936727 by 66 
The aim is to understand the frequency of 66 in 936727.

Moving on to step 1:
When dividing 9 by 66, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 66

Moving on to step 2:
66 goes into 93 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 93 leaves us with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 66

On to step 3:
276 divided by 66 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 12 after subtracting 264 from 276.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 66

Going ahead to step 4:
The number 66 fits into 127 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Deduct 66 from 127 and we're left with 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 66

Step 5:
612 divided by 66 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 1419.0
Subtract 594 from 612 to get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 66

On to step 6:
When dividing 187 by 66, we get 2 with a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 14192.0
Deduct 132 from 187 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
66 goes into 550 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 14192.8
Subtracting 528 from 550 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
66 can be fit into 220 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 14192.83
Subtracting 198 from 220 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 66, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 14192.833
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 14192.833 and a remainder of 0.0022.
