We look at the division of 69530329 by 458 
The aim is to understand the frequency of 458 in 69530329.

On to step 1:
When dividing 6 by 458, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 458

Step 2:
458 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 458

Step 3:
The number 458 fits into 695 1 times, leaving a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 458 from 695 to get 237.
Append the next digit (3) from the dividend to 237 and continue with: 2373 / 458

On to step 4:
458 can be fit into 2373 5 times, resulting in a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2290 from 2373 and we're left with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 458

Moving on to step 5:
When dividing 830 by 458, we get 1 with a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 372 after subtracting 458 from 830.
Bring next digit (3) of the dividend behind the 372 and repeat the process: 3723 / 458

Advancing to step 6:
The number 458 fits into 3723 8 times, leaving a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 1518.0
If we take 3664 away from 3723, we end up with 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 458

Moving on to step 7:
592 divided by 458 is 1 with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 15181.0
Deduct 458 from 592 and we're left with 134.
Fetch the next digit (9) from the dividend, attach it to 134 and continue: 1349 / 458

Step 8:
When dividing 1349 by 458, we get 2 with a remainder of 433.
Put 2 as the next digit of the answer. 
Result so far: 151812.0
Subtracting 916 from 1349 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Going ahead to step 9:
If we divide 4330 by 458, we get 9 and a remainder of 208.
The number 9 becomes the next digit in our result. 
Result so far: 151812.9
Subtract 4122 from 4330 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 10:
If we divide 2080 by 458, we get 4 and a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 151812.94
Subtracting 1832 from 2080 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
458 goes into 2480 5 times with a remainder of 190.
The next digit of our result is 5. 
Result so far: 151812.945
Deduct 2290 from 2480 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.

Going ahead to step 12:
458 goes into 1900 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 151812.9454
If we subtract 1832 from 1900, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
If we divide 680 by 458, we get 1 and a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 151812.94541
Subtracting 458 from 680 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 14:
If we divide 2220 by 458, we get 4 and a remainder of 388.
The number 4 becomes the next digit in our result. 
Result so far: 151812.945414
The remainder is 388 after subtracting 1832 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 15:
The number 458 fits into 3880 8 times, leaving a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 151812.9454148
Subtract 3664 from 3880 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 16:
The number 458 fits into 2160 4 times, leaving a remainder of 328.
The next digit of our result is 4. 
Result so far: 151812.94541484
Subtracting 1832 from 2160 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 151812.94541484, with a leftover of 3.28e-07.
