15163717 divided by 458 
The aim is to understand the frequency of 458 in 15163717.

Moving on to step 1:
If we divide 1 by 458, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 458

Step 2:
458 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 458

On to step 3:
151 divided by 458 is 0 with a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Fetch the next digit (6) from the dividend, attach it to 151 and continue: 1516 / 458

On to step 4:
458 goes into 1516 3 times with a remainder of 142.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1374 from 1516 and we're left with 142.
Include the next digit (3) from the dividend after 142, then repeat: 1423 / 458

Moving on to step 5:
If we divide 1423 by 458, we get 3 and a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 1374 from 1423, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 458

Let's proceed to step 6:
458 can be fit into 497 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 331.0
Deduct 458 from 497 and we're left with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 458

Moving on to step 7:
458 goes into 391 0 times with a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 3310.0
The remainder is 391 after subtracting 0 from 391.
Include the next digit (7) from the dividend after 391, then repeat: 3917 / 458

Moving on to step 8:
The number 458 fits into 3917 8 times, leaving a remainder of 253.
Write down 8 as next digit of the result. 
Result so far: 33108.0
Subtract 3664 from 3917 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Step 9:
If we divide 2530 by 458, we get 5 and a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 33108.5
If we subtract 2290 from 2530, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
When dividing 2400 by 458, we get 5 with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 33108.55
Deduct 2290 from 2400 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 33108.55, with a leftover of 0.11.
