Let's divide 97201 by 66
The aim is to understand the frequency of 66 in 97201.

On to step 1:
9 divided by 66 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 66

Advancing to step 2:
66 goes into 97 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 66 from 97 to get 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 66

Moving on to step 3:
312 divided by 66 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 264 away from 312, we end up with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 66

Advancing to step 4:
66 goes into 480 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
If we subtract 462 from 480, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 66

On to step 5:
181 divided by 66 is 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 1472.0
The remainder is 49 after subtracting 132 from 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 6:
490 divided by 66 is 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 1472.7
Deduct 462 from 490 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1472.74
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 66 fits into 160 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1472.742
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
66 goes into 280 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1472.7424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 66 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1472.74242
The remainder is 28 after subtracting 132 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
If we divide 280 by 66, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1472.742424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
If we divide 160 by 66, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 1472.7424242
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
The number 66 fits into 280 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1472.74242424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1472.74242424 with a remaining 1.6e-08.
