We look at the division of 85217634 by 58 
The aim is to understand the frequency of 58 in 85217634.

Let's proceed to step 1:
When dividing 8 by 58, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 58

Going ahead to step 2:
58 goes into 85 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 58 from 85 to get 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 58

Moving on to step 3:
58 can be fit into 272 4 times, resulting in a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 232 from 272, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 58

Let's proceed to step 4:
58 can be fit into 401 6 times, resulting in a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 348 from 401 and we're left with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 58

Going ahead to step 5:
58 goes into 537 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 1469.0
Subtract 522 from 537 to get 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 58

On to step 6:
58 goes into 156 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 14692.0
Subtract 116 from 156 to get 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 58

Let's proceed to step 7:
If we divide 403 by 58, we get 6 and a remainder of 55.
Use 6 as the next digit of our solution. 
Result so far: 146926.0
Subtracting 348 from 403 leaves us with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 58

On to step 8:
554 divided by 58 is 9 with a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 1469269.0
The remainder is 32 after subtracting 522 from 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
58 can be fit into 320 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1469269.5
Subtract 290 from 320 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
58 can be fit into 300 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1469269.55
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 1469269.55 with a remaining 0.01.
