We're dividing 321636 by 58 
The aim is to understand the frequency of 58 in 321636.

Step 1:
58 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 58

Moving on to step 2:
32 divided by 58 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 58

Advancing to step 3:
The number 58 fits into 321 5 times, leaving a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 290 from 321 to get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 58

Let's proceed to step 4:
The number 58 fits into 316 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we take 290 away from 316, we end up with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 58

Moving on to step 5:
When dividing 263 by 58, we get 4 with a remainder of 31.
The next digit of our result is 4. 
Result so far: 554.0
The remainder is 31 after subtracting 232 from 263.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 58

Advancing to step 6:
When dividing 316 by 58, we get 5 with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5545.0
If we take 290 away from 316, 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.

Step 7:
58 can be fit into 260 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 5545.4
Subtract 232 from 260 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
58 can be fit into 280 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 5545.44
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.

The final result is 5545.44 with a remainder of 0.048.
