We look at the division of 66740179 by 153 
The aim is to understand the frequency of 153 in 66740179.

Going ahead to step 1:
6 divided by 153 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 153

Step 2:
The number 153 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 153

Advancing to step 3:
The number 153 fits into 667 4 times, leaving a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 612 from 667 and we're left with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 153

Step 4:
153 can be fit into 554 3 times, resulting in a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 459 from 554 and we're left with 95.
Take the next digit (0) from the dividend and append it to 95, then repeat: 950 / 153

Let's proceed to step 5:
950 divided by 153 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 436.0
If we subtract 918 from 950, we get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 153

Advancing to step 6:
When dividing 321 by 153, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 4362.0
Deduct 306 from 321 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 153

Moving on to step 7:
157 divided by 153 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 43621.0
If we subtract 153 from 157, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 153

Going ahead to step 8:
The number 153 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 436210.0
Subtracting 0 from 49 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
153 goes into 490 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 436210.3
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
The number 153 fits into 310 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 436210.32
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
The number 153 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 436210.32
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 153 fits into 400 2 times, leaving a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 436210.3202
The remainder is 94 after subtracting 306 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 13:
153 can be fit into 940 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 436210.32026
If we take 918 away from 940, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
When dividing 220 by 153, we get 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 436210.320261
Subtract 153 from 220 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 15:
When dividing 670 by 153, we get 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 436210.3202614
Subtracting 612 from 670 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 16:
When dividing 580 by 153, we get 3 with a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 436210.32026143
If we take 459 away from 580, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final result is 436210.32026143 with a remainder of 1.21e-07.
