Let's divide 7581466 by 458
The aim is to understand the frequency of 458 in 7581466.

Going ahead to step 1:
7 divided by 458 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 458

Let's proceed to step 2:
458 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (8) from the dividend to 75 and continue with: 758 / 458

Moving on to step 3:
458 goes into 758 1 times with a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 458 from 758, we get 300.
Fetch the next digit (1) from the dividend, attach it to 300 and continue: 3001 / 458

Moving on to step 4:
458 can be fit into 3001 6 times, resulting in a remainder of 253.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 2748 from 3001 leaves us with 253.
Take the next digit (4) from the dividend and append it to 253, then repeat: 2534 / 458

Step 5:
458 goes into 2534 5 times with a remainder of 244.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we subtract 2290 from 2534, we get 244.
Grab the next digit (6) from the dividend, add it to 244, then carry on: 2446 / 458

Going ahead to step 6:
When dividing 2446 by 458, we get 5 with a remainder of 156.
The next digit of our result is 5. 
Result so far: 1655.0
The remainder is 156 after subtracting 2290 from 2446.
Include the next digit (6) from the dividend after 156, then repeat: 1566 / 458

Advancing to step 7:
1566 divided by 458 is 3 with a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 16553.0
If we subtract 1374 from 1566, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 8:
If we divide 1920 by 458, we get 4 and a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 16553.4
If we take 1832 away from 1920, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 9:
880 divided by 458 is 1 with a remainder of 422.
Record the quotient 1 as the next digit in the result. 
Result so far: 16553.41
If we subtract 458 from 880, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 10:
The number 458 fits into 4220 9 times, leaving a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 16553.419
If we take 4122 away from 4220, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
If we divide 980 by 458, we get 2 and a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 16553.4192
If we take 916 away from 980, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
The number 458 fits into 640 1 times, leaving a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 16553.41921
Subtracting 458 from 640 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 13:
458 can be fit into 1820 3 times, resulting in a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 16553.419213
Subtract 1374 from 1820 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 14:
458 can be fit into 4460 9 times, resulting in a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 16553.4192139
Deduct 4122 from 4460 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 15:
458 goes into 3380 7 times with a remainder of 174.
Write down 7 as next digit of the result. 
Result so far: 16553.41921397
Subtracting 3206 from 3380 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

In conclusion, the division gives 16553.41921397 with a balance of 1.74e-07.
