We look at the division of 71530486 by 478 
The aim is to understand the frequency of 478 in 71530486.

Advancing to step 1:
7 divided by 478 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 478

Advancing to step 2:
When dividing 71 by 478, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 478

Moving on to step 3:
When dividing 715 by 478, we get 1 with a remainder of 237.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 478 from 715, we get 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 478

Let's proceed to step 4:
2373 divided by 478 is 4 with a remainder of 461.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 1912 away from 2373, we end up with 461.
Grab the next digit (0) from the dividend, add it to 461, then carry on: 4610 / 478

Advancing to step 5:
If we divide 4610 by 478, we get 9 and a remainder of 308.
Write down 9 as next digit of the result. 
Result so far: 149.0
The remainder is 308 after subtracting 4302 from 4610.
Grab the next digit (4) from the dividend, add it to 308, then carry on: 3084 / 478

Going ahead to step 6:
3084 divided by 478 is 6 with a remainder of 216.
Use 6 as the next digit of our solution. 
Result so far: 1496.0
If we subtract 2868 from 3084, we get 216.
Take the next digit (8) from the dividend and append it to 216, then repeat: 2168 / 478

Step 7:
If we divide 2168 by 478, we get 4 and a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 14964.0
Subtracting 1912 from 2168 leaves us with 256.
Bring next digit (6) of the dividend behind the 256 and repeat the process: 2566 / 478

On to step 8:
478 can be fit into 2566 5 times, resulting in a remainder of 176.
The number 5 becomes the next digit in our result. 
Result so far: 149645.0
If we subtract 2390 from 2566, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
If we divide 1760 by 478, we get 3 and a remainder of 326.
Use 3 as the next digit of our solution. 
Result so far: 149645.3
Subtract 1434 from 1760 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
3260 divided by 478 is 6 with a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 149645.36
Subtract 2868 from 3260 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 11:
The number 478 fits into 3920 8 times, leaving a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 149645.368
Subtract 3824 from 3920 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 12:
If we divide 960 by 478, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 149645.3682
Subtracting 956 from 960 leaves us 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.

Let's proceed to step 13:
The number 478 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 149645.3682
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
478 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 149645.3682
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 149645.3682 with a balance of 4e-05.
