We divide 356690 by 86
The aim is to understand the frequency of 86 in 356690.

Advancing to step 1:
86 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 86

Step 2:
The number 86 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 86

Advancing to step 3:
356 divided by 86 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 344 away from 356, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 86

Moving on to step 4:
The number 86 fits into 126 1 times, leaving a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 86 from 126 leaves us with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 86

Going ahead to step 5:
86 goes into 409 4 times with a remainder of 65.
The next digit of our result is 4. 
Result so far: 414.0
If we subtract 344 from 409, we get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 86

On to step 6:
86 goes into 650 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 4147.0
Subtracting 602 from 650 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4147.5
If we take 430 away from 480, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
500 divided by 86 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 4147.55
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 4147.55 with a remaining 0.07.
