We look at the division of 417919 by 86 
The aim is to understand the frequency of 86 in 417919.

Moving on to step 1:
86 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 86

On to step 2:
When dividing 41 by 86, we get 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 86

Going ahead to step 3:
When dividing 417 by 86, we get 4 with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 73 after subtracting 344 from 417.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 86

Advancing to step 4:
The number 86 fits into 739 8 times, leaving a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 688 from 739 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 86

On to step 5:
86 can be fit into 511 5 times, resulting in a remainder of 81.
The next digit of our result is 5. 
Result so far: 485.0
The remainder is 81 after subtracting 430 from 511.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 86

Advancing to step 6:
819 divided by 86 is 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 4859.0
Deduct 774 from 819 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
86 can be fit into 450 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4859.5
The remainder is 20 after subtracting 430 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
86 goes into 200 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4859.52
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 86 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 4859.523
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
When dividing 220 by 86, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 4859.5232
Deduct 172 from 220 and we're left 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 11:
When dividing 480 by 86, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4859.52325
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 12:
If we divide 500 by 86, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 4859.523255
Subtract 430 from 500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 4859.523255 with a balance of 7e-06.
