We look at the division of 349807 by 58 
The aim is to understand the frequency of 58 in 349807.

Step 1:
3 divided by 58 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 58

Advancing to step 2:
If we divide 34 by 58, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 58

Advancing to step 3:
When dividing 349 by 58, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 348 away from 349, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 58

Advancing to step 4:
When dividing 18 by 58, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 60.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 58

Moving on to step 5:
58 can be fit into 180 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 603.0
Subtract 174 from 180 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 58

Going ahead to step 6:
The number 58 fits into 67 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 6031.0
If we subtract 58 from 67, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
When dividing 90 by 58, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 6031.1
If we take 58 away from 90, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
The number 58 fits into 320 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6031.15
Deduct 290 from 320 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
If we divide 300 by 58, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6031.155
Deduct 290 from 300 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 6031.155 and a remainder of 0.001.
