We look at the division of 66144404 by 178 
The aim is to understand the frequency of 178 in 66144404.

On to step 1:
178 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 178

Step 2:
178 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 178

On to step 3:
The number 178 fits into 661 3 times, leaving a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 534 from 661, we get 127.
Include the next digit (4) from the dividend after 127, then repeat: 1274 / 178

Going ahead to step 4:
The number 178 fits into 1274 7 times, leaving a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 1246 from 1274 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 178

Going ahead to step 5:
The number 178 fits into 284 1 times, leaving a remainder of 106.
The next digit of our result is 1. 
Result so far: 371.0
Deduct 178 from 284 and we're left with 106.
Fetch the next digit (4) from the dividend, attach it to 106 and continue: 1064 / 178

Step 6:
1064 divided by 178 is 5 with a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 3715.0
Subtract 890 from 1064 to get 174.
Fetch the next digit (0) from the dividend, attach it to 174 and continue: 1740 / 178

Going ahead to step 7:
The number 178 fits into 1740 9 times, leaving a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 37159.0
If we subtract 1602 from 1740, we get 138.
Fetch the next digit (4) from the dividend, attach it to 138 and continue: 1384 / 178

Moving on to step 8:
1384 divided by 178 is 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 371597.0
The remainder is 138 after subtracting 1246 from 1384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
178 can be fit into 1380 7 times, resulting in a remainder of 134.
The number 7 becomes the next digit in our result. 
Result so far: 371597.7
Subtract 1246 from 1380 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
The number 178 fits into 1340 7 times, leaving a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 371597.77
The remainder is 94 after subtracting 1246 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 371597.77 with a remainder of 0.094.
