We look at the division of 328421 by 58 
The aim is to understand the frequency of 58 in 328421.

Advancing to step 1:
When dividing 3 by 58, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 58

Moving on to step 2:
When dividing 32 by 58, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 58

On to step 3:
When dividing 328 by 58, we get 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 290 from 328 leaves us with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 58

Advancing to step 4:
When dividing 384 by 58, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we take 348 away from 384, we end up with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 58

Step 5:
When dividing 362 by 58, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 566.0
If we take 348 away from 362, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 58

Step 6:
58 can be fit into 141 2 times, resulting in a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 5662.0
If we take 116 away from 141, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
58 goes into 250 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 5662.4
If we subtract 232 from 250, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 58 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 5662.43
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
58 goes into 60 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 5662.431
If we subtract 58 from 60, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 58 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5662.431
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
58 goes into 200 3 times with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 5662.43103
Deduct 174 from 200 and we're left 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.

Let's proceed to step 12:
58 goes into 260 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 5662.431034
If we take 232 away from 260, we end up 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.

Step 13:
If we divide 280 by 58, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 5662.4310344
Deduct 232 from 280 and we're left 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.

After the division, we end up with 5662.4310344 and a remainder of 4.8e-07.
