Let's divide 259619 by 86
The aim is to understand the frequency of 86 in 259619.

Moving on to step 1:
2 divided by 86 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 86

Advancing to step 2:
25 divided by 86 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 86

On to step 3:
When dividing 259 by 86, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 258 from 259 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 86

Let's proceed to step 4:
The number 86 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 16 to get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 86

Step 5:
86 goes into 161 1 times with a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 301.0
Subtracting 86 from 161 leaves us with 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 86

On to step 6:
86 can be fit into 759 8 times, resulting in a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 3018.0
Deduct 688 from 759 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
The number 86 fits into 710 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 3018.8
Deduct 688 from 710 and we're left 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 8:
If we divide 220 by 86, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 3018.82
Subtracting 172 from 220 leaves us 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.

Step 9:
If we divide 480 by 86, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 3018.825
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 86, we get 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 3018.8255
If we take 430 away from 500, we end up with 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 3018.8255 with a balance of 0.0007.
