We look at the division of 12448310 by 478 
The aim is to understand the frequency of 478 in 12448310.

On to step 1:
478 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 478

On to step 2:
478 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 478

Going ahead to step 3:
478 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Bring next digit (4) of the dividend behind the 124 and repeat the process: 1244 / 478

Step 4:
If we divide 1244 by 478, we get 2 and a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 956 from 1244 and we're left with 288.
Include the next digit (8) from the dividend after 288, then repeat: 2888 / 478

Going ahead to step 5:
478 can be fit into 2888 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 2868 away from 2888, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 478

Going ahead to step 6:
478 can be fit into 203 0 times, resulting in a remainder of 203.
The next digit of our result is 0. 
Result so far: 260.0
The remainder is 203 after subtracting 0 from 203.
Bring next digit (1) of the dividend behind the 203 and repeat the process: 2031 / 478

Advancing to step 7:
The number 478 fits into 2031 4 times, leaving a remainder of 119.
Record the quotient 4 as the next digit in the result. 
Result so far: 2604.0
If we subtract 1912 from 2031, we get 119.
Bring next digit (0) of the dividend behind the 119 and repeat the process: 1190 / 478

On to step 8:
If we divide 1190 by 478, we get 2 and a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 26042.0
The remainder is 234 after subtracting 956 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
When dividing 2340 by 478, we get 4 with a remainder of 428.
The next digit of our result is 4. 
Result so far: 26042.4
Deduct 1912 from 2340 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 10:
When dividing 4280 by 478, we get 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 26042.48
Subtracting 3824 from 4280 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 11:
478 goes into 4560 9 times with a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 26042.489
If we take 4302 away from 4560, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
478 goes into 2580 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 26042.4895
Deduct 2390 from 2580 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 13:
478 can be fit into 1900 3 times, resulting in a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 26042.48953
Deduct 1434 from 1900 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 14:
478 goes into 4660 9 times with a remainder of 358.
Put 9 as the next digit of the answer. 
Result so far: 26042.489539
Subtract 4302 from 4660 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 15:
If we divide 3580 by 478, we get 7 and a remainder of 234.
Put 7 as the next digit of the answer. 
Result so far: 26042.4895397
If we take 3346 away from 3580, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 16:
When dividing 2340 by 478, we get 4 with a remainder of 428.
Write down 4 as next digit of the result. 
Result so far: 26042.48953974
If we take 1912 away from 2340, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final outcome is 26042.48953974, with a leftover of 4.28e-07.
