We look at the division of 85409 by 58 
The aim is to understand the frequency of 58 in 85409.

Moving on to step 1:
If we divide 8 by 58, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 58

Let's proceed to step 2:
If we divide 85 by 58, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 58 from 85.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 58

Moving on to step 3:
The number 58 fits into 274 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 42 after subtracting 232 from 274.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 58

Moving on to step 4:
When dividing 420 by 58, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 147.0
Subtracting 406 from 420 leaves us with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 58

Going ahead to step 5:
If we divide 149 by 58, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 1472.0
The remainder is 33 after subtracting 116 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 6:
330 divided by 58 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1472.5
Subtracting 290 from 330 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
The number 58 fits into 400 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 1472.56
If we subtract 348 from 400, we 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 8:
58 can be fit into 520 8 times, resulting in a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 1472.568
If we subtract 464 from 520, we 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.

On to step 9:
If we divide 560 by 58, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1472.5689
If we subtract 522 from 560, we 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 10:
When dividing 380 by 58, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1472.56896
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
58 goes into 320 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 1472.568965
If we take 290 away from 320, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 58, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1472.5689655
If we subtract 290 from 300, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1472.5689655, and the remainder is 1e-07.
