We're dividing 66611979 by 254 
The aim is to understand the frequency of 254 in 66611979.

Going ahead to step 1:
254 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 254

Going ahead to step 2:
When dividing 66 by 254, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 254

On to step 3:
If we divide 666 by 254, we get 2 and a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 508 from 666 to get 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 254

Let's proceed to step 4:
254 can be fit into 1581 6 times, resulting in a remainder of 57.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 1524 from 1581 and we're left with 57.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 254

Let's proceed to step 5:
254 can be fit into 571 2 times, resulting in a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 262.0
If we subtract 508 from 571, we get 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 254

Let's proceed to step 6:
The number 254 fits into 639 2 times, leaving a remainder of 131.
The next digit of our result is 2. 
Result so far: 2622.0
If we take 508 away from 639, we end up with 131.
Take the next digit (7) from the dividend and append it to 131, then repeat: 1317 / 254

Going ahead to step 7:
254 goes into 1317 5 times with a remainder of 47.
Use 5 as the next digit of our solution. 
Result so far: 26225.0
Subtract 1270 from 1317 to get 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 254

On to step 8:
479 divided by 254 is 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 262251.0
If we subtract 254 from 479, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 9:
If we divide 2250 by 254, we get 8 and a remainder of 218.
Record the quotient 8 as the next digit in the result. 
Result so far: 262251.8
Subtracting 2032 from 2250 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
254 can be fit into 2180 8 times, resulting in a remainder of 148.
The next digit of our result is 8. 
Result so far: 262251.88
Subtracting 2032 from 2180 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The quotient of the division is 262251.88, and the remainder is 0.148.
