889393 ÷ 86 
The aim is to understand the frequency of 86 in 889393.

Step 1:
8 divided by 86 is 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.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 86

Let's proceed to step 2:
When dividing 88 by 86, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 86 from 88, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 86

Step 3:
The number 86 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 29, we get 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 86

Let's proceed to step 4:
86 goes into 293 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtracting 258 from 293 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 86

Moving on to step 5:
The number 86 fits into 359 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1034.0
Subtracting 344 from 359 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 86

Step 6:
If we divide 153 by 86, we get 1 and a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 10341.0
Subtract 86 from 153 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.

Going ahead to step 7:
670 divided by 86 is 7 with a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 10341.7
Deduct 602 from 670 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
86 goes into 680 7 times with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 10341.77
If we subtract 602 from 680, we 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.

After the division, we end up with 10341.77 and a remainder of 0.078.
