We're dividing 91705390 by 478 
The aim is to understand the frequency of 478 in 91705390.

Let's proceed to step 1:
When dividing 9 by 478, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 478

Going ahead to step 2:
If we divide 91 by 478, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (7) from the dividend, add it to 91, then carry on: 917 / 478

Moving on to step 3:
If we divide 917 by 478, we get 1 and a remainder of 439.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 478 from 917, we get 439.
Take the next digit (0) from the dividend and append it to 439, then repeat: 4390 / 478

Advancing to step 4:
The number 478 fits into 4390 9 times, leaving a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 88 after subtracting 4302 from 4390.
Append the next digit (5) from the dividend to 88 and continue with: 885 / 478

Going ahead to step 5:
885 divided by 478 is 1 with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we take 478 away from 885, we end up with 407.
Take the next digit (3) from the dividend and append it to 407, then repeat: 4073 / 478

On to step 6:
478 can be fit into 4073 8 times, resulting in a remainder of 249.
Use 8 as the next digit of our solution. 
Result so far: 1918.0
The remainder is 249 after subtracting 3824 from 4073.
Include the next digit (9) from the dividend after 249, then repeat: 2499 / 478

Moving on to step 7:
478 can be fit into 2499 5 times, resulting in a remainder of 109.
The next digit of our result is 5. 
Result so far: 19185.0
If we take 2390 away from 2499, we end up with 109.
Include the next digit (0) from the dividend after 109, then repeat: 1090 / 478

Let's proceed to step 8:
If we divide 1090 by 478, we get 2 and a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 191852.0
Subtract 956 from 1090 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.

Let's proceed to step 9:
1340 divided by 478 is 2 with a remainder of 384.
The next digit of our result is 2. 
Result so far: 191852.2
Subtract 956 from 1340 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
478 can be fit into 3840 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 191852.28
If we take 3824 away from 3840, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 478 fits into 160 0 times, leaving a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 191852.28
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
1600 divided by 478 is 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 191852.2803
Deduct 1434 from 1600 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 13:
1660 divided by 478 is 3 with a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 191852.28033
Subtract 1434 from 1660 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

In conclusion, the division gives 191852.28033 with a balance of 0.000226.
