Let's divide 319633 by 86
The aim is to understand the frequency of 86 in 319633.

On to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 86

Advancing to step 2:
The number 86 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 86

Step 3:
If we divide 319 by 86, we get 3 and a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 258 away from 319, we end up with 61.
Bring next digit (6) of the dividend behind the 61 and repeat the process: 616 / 86

Let's proceed to step 4:
616 divided by 86 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 602 away from 616, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 86

Step 5:
If we divide 143 by 86, we get 1 and a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 371.0
Subtract 86 from 143 to get 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 86

Moving on to step 6:
The number 86 fits into 573 6 times, leaving a remainder of 57.
The next digit of our result is 6. 
Result so far: 3716.0
Deduct 516 from 573 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
If we divide 570 by 86, we get 6 and a remainder of 54.
The next digit of our result is 6. 
Result so far: 3716.6
The remainder is 54 after subtracting 516 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
If we divide 540 by 86, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 3716.66
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 3716.66 and a remainder of 0.024.
