Let's divide 619525 by 86
The aim is to understand the frequency of 86 in 619525.

On to step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 86

Let's proceed to step 2:
If we divide 61 by 86, we get 0 and a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 86

On to step 3:
86 can be fit into 619 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 602 from 619 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 86

On to step 4:
86 can be fit into 175 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 172 from 175 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 86

On to step 5:
32 divided by 86 is 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 720.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 86

Step 6:
The number 86 fits into 325 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 7203.0
Subtract 258 from 325 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.

On to step 7:
When dividing 670 by 86, we get 7 with a remainder of 68.
The number 7 becomes the next digit in our result. 
Result so far: 7203.7
Subtract 602 from 670 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 8:
86 can be fit into 680 7 times, resulting in a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 7203.77
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.

The final result is 7203.77 with a remainder of 0.078.
