We look at the division of 246177 by 66 
The aim is to understand the frequency of 66 in 246177.

Step 1:
When dividing 2 by 66, we get 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.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 66

Going ahead to step 2:
If we divide 24 by 66, we get 0 and a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 66

Moving on to step 3:
The number 66 fits into 246 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 48 after subtracting 198 from 246.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 66

Going ahead to step 4:
66 can be fit into 481 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 462 from 481 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 66

Step 5:
The number 66 fits into 197 2 times, leaving a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 372.0
Deduct 132 from 197 and we're left with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 66

On to step 6:
The number 66 fits into 657 9 times, leaving a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 3729.0
If we take 594 away from 657, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
66 goes into 630 9 times with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 3729.9
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:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3729.95
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.

Advancing to step 9:
If we divide 300 by 66, we get 4 and a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 3729.954
If we subtract 264 from 300, we 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.
Use 5 as the next digit of our solution. 
Result so far: 3729.9545
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.

Going ahead to step 11:
When dividing 300 by 66, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3729.95454
If we subtract 264 from 300, we 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.

Step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3729.954545
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.

Step 13:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 3729.9545454
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.

Advancing to step 14:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3729.95454545
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.

The quotient of the division is 3729.95454545, and the remainder is 3e-08.
