We're dividing 137204 by 58 
The aim is to understand the frequency of 58 in 137204.

On to step 1:
The number 58 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 58

Moving on to step 2:
58 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 58

Let's proceed to step 3:
137 divided by 58 is 2 with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 116 away from 137, we end up with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 58

On to step 4:
If we divide 212 by 58, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 38 after subtracting 174 from 212.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 58

Going ahead to step 5:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
If we subtract 348 from 380, we get 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 58

Step 6:
The number 58 fits into 324 5 times, leaving a remainder of 34.
The next digit of our result is 5. 
Result so far: 2365.0
If we take 290 away from 324, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
If we divide 340 by 58, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2365.5
The remainder is 50 after subtracting 290 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 58 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2365.58
Deduct 464 from 500 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
58 goes into 360 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 2365.586
Subtracting 348 from 360 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 58, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2365.5862
If we subtract 116 from 120, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 58, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2365.5862
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 58, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 2365.586206
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
If we divide 520 by 58, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 2365.5862068
Deduct 464 from 520 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
When dividing 560 by 58, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 2365.58620689
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 2365.58620689, with a leftover of 3.8e-08.
