We're dividing 268788 by 66 
The aim is to understand the frequency of 66 in 268788.

Moving on to step 1:
2 divided by 66 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 66

Step 2:
The number 66 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 66

Going ahead to step 3:
66 can be fit into 268 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 264 from 268, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 66

Advancing to step 4:
When dividing 47 by 66, we get 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 47 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 66

Advancing to step 5:
478 divided by 66 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
If we subtract 462 from 478, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 66

Let's proceed to step 6:
66 can be fit into 168 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 4072.0
If we take 132 away from 168, 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.

Going ahead to step 7:
66 goes into 360 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4072.5
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.

Going ahead to step 8:
66 goes into 300 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4072.54
Deduct 264 from 300 and we're left 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.

Let's proceed to step 9:
360 divided by 66 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4072.545
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.

Advancing to step 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4072.5454
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.

On to step 11:
If we divide 360 by 66, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 4072.54545
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.

Let's proceed to step 12:
If we divide 300 by 66, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4072.545454
Subtract 264 from 300 to 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 13:
66 goes into 360 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 4072.5454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 4072.54545454
Deduct 264 from 300 and we're left 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.

The final outcome is 4072.54545454, with a leftover of 3.6e-08.
