We look at the division of 456057 by 86 
The aim is to understand the frequency of 86 in 456057.

Going ahead to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 86

Moving on to step 2:
The number 86 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 86

Going ahead to step 3:
86 goes into 456 5 times with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 430 from 456, we get 26.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 86

On to step 4:
If we divide 260 by 86, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we subtract 258 from 260, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 86

Moving on to step 5:
The number 86 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 530.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 86

Moving on to step 6:
If we divide 257 by 86, we get 2 and a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 5302.0
Subtracting 172 from 257 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
850 divided by 86 is 9 with a remainder of 76.
Use 9 as the next digit of our solution. 
Result so far: 5302.9
Deduct 774 from 850 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 8:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 5302.98
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 5302.988
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 5302.988 with a remainder of 0.0032.
