We're dividing 357655 by 86 
The aim is to understand the frequency of 86 in 357655.

Moving on to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 86

Let's proceed to step 2:
The number 86 fits into 35 0 times, leaving a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 86

Let's proceed to step 3:
86 goes into 357 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 13 after subtracting 344 from 357.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 86

Step 4:
86 goes into 136 1 times with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 86 from 136 to get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 86

Step 5:
The number 86 fits into 505 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 415.0
Subtracting 430 from 505 leaves us with 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 86

Let's proceed to step 6:
755 divided by 86 is 8 with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 4158.0
Subtract 688 from 755 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 86 is 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 4158.7
If we subtract 602 from 670, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
If we divide 680 by 86, we get 7 and a remainder of 78.
The next digit of our result is 7. 
Result so far: 4158.77
Subtract 602 from 680 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 4158.77, with a leftover of 0.078.
