408003 divided by 58 
The aim is to understand the frequency of 58 in 408003.

Step 1:
58 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 58

Moving on to step 2:
The number 58 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 58

Moving on to step 3:
58 can be fit into 408 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 406 from 408 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 58

Advancing to step 4:
20 divided by 58 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 58

On to step 5:
58 goes into 200 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 703.0
Subtracting 174 from 200 leaves us with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 58

Advancing to step 6:
The number 58 fits into 263 4 times, leaving a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 7034.0
Subtract 232 from 263 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
The number 58 fits into 310 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 7034.5
Subtract 290 from 310 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 58, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 7034.53
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 58, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 7034.534
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
58 goes into 280 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7034.5344
Subtracting 232 from 280 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 7034.5344, with a leftover of 0.00048.
