We look at the division of 515873 by 58 
The aim is to understand the frequency of 58 in 515873.

Moving on to step 1:
The number 58 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 58

Advancing to step 2:
When dividing 51 by 58, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 58

Going ahead to step 3:
The number 58 fits into 515 8 times, leaving a remainder of 51.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 464 from 515, we get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 58

Advancing to step 4:
58 goes into 518 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 464 from 518, we get 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 58

Going ahead to step 5:
58 goes into 547 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 889.0
The remainder is 25 after subtracting 522 from 547.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 58

Going ahead to step 6:
253 divided by 58 is 4 with a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 8894.0
If we subtract 232 from 253, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
58 can be fit into 210 3 times, resulting in a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 8894.3
Subtracting 174 from 210 leaves us 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 8:
58 can be fit into 360 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 8894.36
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.

Going ahead to step 9:
120 divided by 58 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 8894.362
Deduct 116 from 120 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 58 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8894.362
If we subtract 0 from 40, we 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.

Going ahead to step 11:
When dividing 400 by 58, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8894.36206
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
58 goes into 520 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 8894.362068
Subtract 464 from 520 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
58 goes into 560 9 times with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 8894.3620689
Subtract 522 from 560 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
58 goes into 380 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8894.36206896
If we take 348 away from 380, 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.

The final result is 8894.36206896 with a remainder of 3.2e-08.
