We're dividing 720148 by 86 
The aim is to understand the frequency of 86 in 720148.

Moving on to step 1:
7 divided by 86 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 86

On to step 2:
86 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 86

Advancing to step 3:
720 divided by 86 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 688 from 720, we get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 86

Moving on to step 4:
321 divided by 86 is 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 258 from 321 and we're left with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 86

On to step 5:
The number 86 fits into 634 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 837.0
The remainder is 32 after subtracting 602 from 634.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 86

Step 6:
328 divided by 86 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 8373.0
Subtracting 258 from 328 leaves us 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.

On to step 7:
If we divide 700 by 86, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8373.8
Subtracting 688 from 700 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 86, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 8373.81
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 86, we get 3 and a remainder of 82.
The next digit of our result is 3. 
Result so far: 8373.813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
86 goes into 820 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 8373.8139
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
86 can be fit into 460 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 8373.81395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 8373.813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
When dividing 420 by 86, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 8373.8139534
Subtracting 344 from 420 leaves us 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 14:
86 goes into 760 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 8373.81395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 8373.81395348 with a remaining 7.2e-08.
