We're dividing 64715451 by 478 
The aim is to understand the frequency of 478 in 64715451.

Going ahead to step 1:
When dividing 6 by 478, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 478

Moving on to step 2:
478 can be fit into 64 0 times, resulting in a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 478

Going ahead to step 3:
If we divide 647 by 478, we get 1 and a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 478 away from 647, we end up with 169.
Bring next digit (1) of the dividend behind the 169 and repeat the process: 1691 / 478

Going ahead to step 4:
The number 478 fits into 1691 3 times, leaving a remainder of 257.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1434 from 1691 and we're left with 257.
Fetch the next digit (5) from the dividend, attach it to 257 and continue: 2575 / 478

Let's proceed to step 5:
The number 478 fits into 2575 5 times, leaving a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
If we subtract 2390 from 2575, we get 185.
Append the next digit (4) from the dividend to 185 and continue with: 1854 / 478

Let's proceed to step 6:
1854 divided by 478 is 3 with a remainder of 420.
The number 3 becomes the next digit in our result. 
Result so far: 1353.0
The remainder is 420 after subtracting 1434 from 1854.
Append the next digit (5) from the dividend to 420 and continue with: 4205 / 478

Moving on to step 7:
478 can be fit into 4205 8 times, resulting in a remainder of 381.
Use 8 as the next digit of our solution. 
Result so far: 13538.0
If we take 3824 away from 4205, we end up with 381.
Fetch the next digit (1) from the dividend, attach it to 381 and continue: 3811 / 478

On to step 8:
The number 478 fits into 3811 7 times, leaving a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 135387.0
Subtract 3346 from 3811 to get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 9:
If we divide 4650 by 478, we get 9 and a remainder of 348.
The next digit of our result is 9. 
Result so far: 135387.9
If we subtract 4302 from 4650, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
The number 478 fits into 3480 7 times, leaving a remainder of 134.
Record the quotient 7 as the next digit in the result. 
Result so far: 135387.97
The remainder is 134 after subtracting 3346 from 3480.
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 11:
478 goes into 1340 2 times with a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 135387.972
If we subtract 956 from 1340, we 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 12:
478 goes into 3840 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 135387.9728
Subtract 3824 from 3840 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 478 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 135387.9728
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
When dividing 1600 by 478, we get 3 with a remainder of 166.
Put 3 as the next digit of the answer. 
Result so far: 135387.972803
The remainder is 166 after subtracting 1434 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 15:
478 can be fit into 1660 3 times, resulting in a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 135387.9728033
If we take 1434 away from 1660, we end up with 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 135387.9728033 with a balance of 2.26e-06.
