68413404 ÷ 458 
The aim is to understand the frequency of 458 in 68413404.

On to step 1:
When dividing 6 by 458, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 458

Let's proceed to step 2:
The number 458 fits into 68 0 times, leaving a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 458

On to step 3:
684 divided by 458 is 1 with a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 226 after subtracting 458 from 684.
Fetch the next digit (1) from the dividend, attach it to 226 and continue: 2261 / 458

On to step 4:
The number 458 fits into 2261 4 times, leaving a remainder of 429.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1832 from 2261, we get 429.
Grab the next digit (3) from the dividend, add it to 429, then carry on: 4293 / 458

Step 5:
458 can be fit into 4293 9 times, resulting in a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
The remainder is 171 after subtracting 4122 from 4293.
Take the next digit (4) from the dividend and append it to 171, then repeat: 1714 / 458

Step 6:
The number 458 fits into 1714 3 times, leaving a remainder of 340.
The next digit of our result is 3. 
Result so far: 1493.0
If we subtract 1374 from 1714, we get 340.
Grab the next digit (0) from the dividend, add it to 340, then carry on: 3400 / 458

Advancing to step 7:
The number 458 fits into 3400 7 times, leaving a remainder of 194.
The next digit of our result is 7. 
Result so far: 14937.0
Subtracting 3206 from 3400 leaves us with 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 458

Moving on to step 8:
1944 divided by 458 is 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 149374.0
Subtracting 1832 from 1944 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
When dividing 1120 by 458, we get 2 with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 149374.2
If we subtract 916 from 1120, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 10:
2040 divided by 458 is 4 with a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 149374.24
Subtracting 1832 from 2040 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 11:
458 goes into 2080 4 times with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 149374.244
The remainder is 248 after subtracting 1832 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 149374.244 with a remaining 0.0248.
