We're dividing 76657728 by 478 
The aim is to understand the frequency of 478 in 76657728.

Step 1:
478 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 478

Moving on to step 2:
478 goes into 76 0 times with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 478

Let's proceed to step 3:
The number 478 fits into 766 1 times, leaving a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 478 away from 766, we end up with 288.
Append the next digit (5) from the dividend to 288 and continue with: 2885 / 478

Going ahead to step 4:
2885 divided by 478 is 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 2868 from 2885 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 478

Let's proceed to step 5:
478 goes into 177 0 times with a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 177, we get 177.
Include the next digit (7) from the dividend after 177, then repeat: 1777 / 478

Going ahead to step 6:
478 goes into 1777 3 times with a remainder of 343.
Write down 3 as next digit of the result. 
Result so far: 1603.0
Deduct 1434 from 1777 and we're left with 343.
Grab the next digit (2) from the dividend, add it to 343, then carry on: 3432 / 478

Advancing to step 7:
3432 divided by 478 is 7 with a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 16037.0
If we subtract 3346 from 3432, we get 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 478

Going ahead to step 8:
The number 478 fits into 868 1 times, leaving a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 160371.0
The remainder is 390 after subtracting 478 from 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 9:
3900 divided by 478 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 160371.8
The remainder is 76 after subtracting 3824 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 478 fits into 760 1 times, leaving a remainder of 282.
The next digit of our result is 1. 
Result so far: 160371.81
Subtracting 478 from 760 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 11:
If we divide 2820 by 478, we get 5 and a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 160371.815
The remainder is 430 after subtracting 2390 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 12:
4300 divided by 478 is 8 with a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 160371.8158
The remainder is 476 after subtracting 3824 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 13:
478 can be fit into 4760 9 times, resulting in a remainder of 458.
Write down 9 as next digit of the result. 
Result so far: 160371.81589
Subtract 4302 from 4760 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 14:
The number 478 fits into 4580 9 times, leaving a remainder of 278.
The next digit of our result is 9. 
Result so far: 160371.815899
Subtract 4302 from 4580 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final result is 160371.815899 with a remainder of 2.78e-05.
