We look at the division of 421314 by 58 
The aim is to understand the frequency of 58 in 421314.

Step 1:
When dividing 4 by 58, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 58

Moving on to step 2:
The number 58 fits into 42 0 times, leaving a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 58

Advancing to step 3:
The number 58 fits into 421 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 406 away from 421, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 58

On to step 4:
153 divided by 58 is 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we take 116 away from 153, we end up with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 58

Step 5:
371 divided by 58 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 726.0
If we subtract 348 from 371, we get 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 58

Going ahead to step 6:
58 goes into 234 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7264.0
Subtract 232 from 234 to 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.

Going ahead to step 7:
20 divided by 58 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7264.0
Deduct 0 from 20 and we're left with 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:
58 goes into 200 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 7264.03
If we subtract 174 from 200, we get 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 9:
If we divide 260 by 58, we get 4 and a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 7264.034
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.

Going ahead to step 10:
When dividing 280 by 58, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7264.0344
The remainder is 48 after subtracting 232 from 280.
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 7264.0344, with a leftover of 0.00048.
