We look at the division of 77608181 by 254 
The aim is to understand the frequency of 254 in 77608181.

Moving on to step 1:
254 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 254

Going ahead to step 2:
The number 254 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 254

Advancing to step 3:
254 goes into 776 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 762 from 776, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 254

Step 4:
When dividing 140 by 254, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 30.0
If we subtract 0 from 140, we get 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 254

Going ahead to step 5:
254 goes into 1408 5 times with a remainder of 138.
Put 5 as the next digit of the answer. 
Result so far: 305.0
If we take 1270 away from 1408, we end up with 138.
Fetch the next digit (1) from the dividend, attach it to 138 and continue: 1381 / 254

Going ahead to step 6:
When dividing 1381 by 254, we get 5 with a remainder of 111.
Record the quotient 5 as the next digit in the result. 
Result so far: 3055.0
The remainder is 111 after subtracting 1270 from 1381.
Bring next digit (8) of the dividend behind the 111 and repeat the process: 1118 / 254

Going ahead to step 7:
254 goes into 1118 4 times with a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 30554.0
If we take 1016 away from 1118, we end up with 102.
Grab the next digit (1) from the dividend, add it to 102, then carry on: 1021 / 254

Moving on to step 8:
The number 254 fits into 1021 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 305544.0
The remainder is 5 after subtracting 1016 from 1021.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 254 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 305544.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 254 fits into 500 1 times, leaving a remainder of 246.
The next digit of our result is 1. 
Result so far: 305544.01
The remainder is 246 after subtracting 254 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 11:
254 can be fit into 2460 9 times, resulting in a remainder of 174.
Write down 9 as next digit of the result. 
Result so far: 305544.019
The remainder is 174 after subtracting 2286 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 12:
The number 254 fits into 1740 6 times, leaving a remainder of 216.
The next digit of our result is 6. 
Result so far: 305544.0196
Deduct 1524 from 1740 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 13:
2160 divided by 254 is 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 305544.01968
If we take 2032 away from 2160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
254 goes into 1280 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 305544.019685
The remainder is 10 after subtracting 1270 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 15:
The number 254 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 305544.019685
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
254 can be fit into 1000 3 times, resulting in a remainder of 238.
Use 3 as the next digit of our solution. 
Result so far: 305544.01968503
Subtracting 762 from 1000 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

The quotient of the division is 305544.01968503, and the remainder is 2.38e-07.
