We look at the division of 79804366 by 478 
The aim is to understand the frequency of 478 in 79804366.

Advancing to step 1:
If we divide 7 by 478, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 478

Advancing to step 2:
When dividing 79 by 478, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 478

Step 3:
When dividing 798 by 478, we get 1 with a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 478 from 798 leaves us with 320.
Take the next digit (0) from the dividend and append it to 320, then repeat: 3200 / 478

Moving on to step 4:
The number 478 fits into 3200 6 times, leaving a remainder of 332.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2868 from 3200 and we're left with 332.
Include the next digit (4) from the dividend after 332, then repeat: 3324 / 478

On to step 5:
If we divide 3324 by 478, we get 6 and a remainder of 456.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we subtract 2868 from 3324, we get 456.
Take the next digit (3) from the dividend and append it to 456, then repeat: 4563 / 478

Advancing to step 6:
4563 divided by 478 is 9 with a remainder of 261.
Use 9 as the next digit of our solution. 
Result so far: 1669.0
If we subtract 4302 from 4563, we get 261.
Include the next digit (6) from the dividend after 261, then repeat: 2616 / 478

On to step 7:
478 can be fit into 2616 5 times, resulting in a remainder of 226.
Use 5 as the next digit of our solution. 
Result so far: 16695.0
Subtract 2390 from 2616 to get 226.
Include the next digit (6) from the dividend after 226, then repeat: 2266 / 478

Advancing to step 8:
2266 divided by 478 is 4 with a remainder of 354.
The next digit of our result is 4. 
Result so far: 166954.0
The remainder is 354 after subtracting 1912 from 2266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
3540 divided by 478 is 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 166954.7
If we subtract 3346 from 3540, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 10:
The number 478 fits into 1940 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 166954.74
Subtracting 1912 from 1940 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
478 can be fit into 280 0 times, resulting in a remainder of 280.
The next digit of our result is 0. 
Result so far: 166954.74
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 12:
If we divide 2800 by 478, we get 5 and a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 166954.7405
Subtract 2390 from 2800 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 13:
When dividing 4100 by 478, we get 8 with a remainder of 276.
The next digit of our result is 8. 
Result so far: 166954.74058
If we take 3824 away from 4100, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Step 14:
When dividing 2760 by 478, we get 5 with a remainder of 370.
The next digit of our result is 5. 
Result so far: 166954.740585
If we subtract 2390 from 2760, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 15:
3700 divided by 478 is 7 with a remainder of 354.
Write down 7 as next digit of the result. 
Result so far: 166954.7405857
If we take 3346 away from 3700, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 16:
478 can be fit into 3540 7 times, resulting in a remainder of 194.
Use 7 as the next digit of our solution. 
Result so far: 166954.74058577
If we subtract 3346 from 3540, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

After the division, we end up with 166954.74058577 and a remainder of 1.94e-07.
