882963 ÷ 86 
The aim is to understand the frequency of 86 in 882963.

Going ahead to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 86

Moving on to step 2:
86 goes into 88 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 86 away from 88, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 86

Advancing to step 3:
When dividing 22 by 86, we get 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 22, we get 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 86

Advancing to step 4:
86 can be fit into 229 2 times, resulting in a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 172 away from 229, we end up with 57.
Take the next digit (6) from the dividend and append it to 57, then repeat: 576 / 86

Step 5:
86 goes into 576 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 1026.0
If we subtract 516 from 576, we get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 86

On to step 6:
86 goes into 603 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10267.0
Deduct 602 from 603 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
86 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10267.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 10267.01
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
When dividing 140 by 86, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 10267.011
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 10267.011 and a remainder of 0.0054.
