We look at the division of 818605 by 58 
The aim is to understand the frequency of 58 in 818605.

On to step 1:
If we divide 8 by 58, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 58

On to step 2:
58 goes into 81 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 58 from 81, we get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 58

Advancing to step 3:
58 can be fit into 238 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 232 from 238 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 58

Advancing to step 4:
58 can be fit into 66 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Deduct 58 from 66 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 58

Moving on to step 5:
The number 58 fits into 80 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1411.0
Subtract 58 from 80 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 58

Going ahead to step 6:
When dividing 225 by 58, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 14113.0
Deduct 174 from 225 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
58 goes into 510 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 14113.8
Subtracting 464 from 510 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
460 divided by 58 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 14113.87
If we take 406 away from 460, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
When dividing 540 by 58, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 14113.879
If we take 522 away from 540, we end up with 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 10:
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: 14113.8793
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 58, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 14113.87931
Subtract 58 from 60 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.

Advancing to step 12:
20 divided by 58 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14113.87931
If we subtract 0 from 20, we get 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 13:
58 goes into 200 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 14113.8793103
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.

Going ahead to step 14:
58 can be fit into 260 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 14113.87931034
If we subtract 232 from 260, we 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.

The final result is 14113.87931034 with a remainder of 2.8e-08.
