We look at the division of 27590225 by 478 
The aim is to understand the frequency of 478 in 27590225.

Moving on to step 1:
2 divided by 478 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 478

Advancing to step 2:
The number 478 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 478

Going ahead to step 3:
When dividing 275 by 478, we get 0 with a remainder of 275.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 275 after subtracting 0 from 275.
Append the next digit (9) from the dividend to 275 and continue with: 2759 / 478

Moving on to step 4:
2759 divided by 478 is 5 with a remainder of 369.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2390 from 2759 and we're left with 369.
Take the next digit (0) from the dividend and append it to 369, then repeat: 3690 / 478

On to step 5:
The number 478 fits into 3690 7 times, leaving a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we subtract 3346 from 3690, we get 344.
Include the next digit (2) from the dividend after 344, then repeat: 3442 / 478

On to step 6:
When dividing 3442 by 478, we get 7 with a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 577.0
Subtract 3346 from 3442 to get 96.
Include the next digit (2) from the dividend after 96, then repeat: 962 / 478

Going ahead to step 7:
478 goes into 962 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 5772.0
If we take 956 away from 962, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 478

On to step 8:
478 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 57720.0
The remainder is 65 after subtracting 0 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
650 divided by 478 is 1 with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 57720.1
If we take 478 away from 650, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
The number 478 fits into 1720 3 times, leaving a remainder of 286.
Write down 3 as next digit of the result. 
Result so far: 57720.13
The remainder is 286 after subtracting 1434 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 11:
478 goes into 2860 5 times with a remainder of 470.
Write down 5 as next digit of the result. 
Result so far: 57720.135
If we subtract 2390 from 2860, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 12:
If we divide 4700 by 478, we get 9 and a remainder of 398.
The next digit of our result is 9. 
Result so far: 57720.1359
If we subtract 4302 from 4700, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 13:
478 can be fit into 3980 8 times, resulting in a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 57720.13598
Deduct 3824 from 3980 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 14:
The number 478 fits into 1560 3 times, leaving a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 57720.135983
If we subtract 1434 from 1560, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 15:
If we divide 1260 by 478, we get 2 and a remainder of 304.
Record the quotient 2 as the next digit in the result. 
Result so far: 57720.1359832
The remainder is 304 after subtracting 956 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 16:
478 goes into 3040 6 times with a remainder of 172.
The next digit of our result is 6. 
Result so far: 57720.13598326
Subtract 2868 from 3040 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 57720.13598326 and a remainder of 1.72e-07.
