We look at the division of 83815083 by 58 
The aim is to understand the frequency of 58 in 83815083.

Step 1:
8 divided by 58 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 58

Let's proceed to step 2:
If we divide 83 by 58, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 25 after subtracting 58 from 83.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 58

Advancing to step 3:
58 goes into 258 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 232 from 258 leaves us with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 58

Moving on to step 4:
The number 58 fits into 261 4 times, leaving a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 144.0
Deduct 232 from 261 and we're left with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 58

On to step 5:
295 divided by 58 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1445.0
Deduct 290 from 295 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 58

On to step 6:
If we divide 50 by 58, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 14450.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 58

Step 7:
If we divide 508 by 58, we get 8 and a remainder of 44.
The next digit of our result is 8. 
Result so far: 144508.0
If we take 464 away from 508, we end up with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 58

Advancing to step 8:
The number 58 fits into 443 7 times, leaving a remainder of 37.
The next digit of our result is 7. 
Result so far: 1445087.0
If we subtract 406 from 443, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
370 divided by 58 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 1445087.6
If we take 348 away from 370, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
The number 58 fits into 220 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1445087.63
Subtracting 174 from 220 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.

Step 11:
When dividing 460 by 58, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 1445087.637
Deduct 406 from 460 and we're left 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.

Step 12:
If we divide 540 by 58, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1445087.6379
Deduct 522 from 540 and we're left 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.

Advancing to step 13:
58 can be fit into 180 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 1445087.63793
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
58 can be fit into 60 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1445087.637931
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
The number 58 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1445087.637931
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.

Moving on to step 16:
If we divide 200 by 58, we get 3 and a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 1445087.63793103
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 1445087.63793103 and a remainder of 2.6e-08.
