Let's divide 99830 by 86
The aim is to understand the frequency of 86 in 99830.

Let's proceed to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 86

Let's proceed to step 2:
If we divide 99 by 86, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 99 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 86

On to step 3:
86 can be fit into 138 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 86 from 138 leaves us with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 86

Step 4:
The number 86 fits into 523 6 times, leaving a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 516 away from 523, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 86

Moving on to step 5:
70 divided by 86 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1160.0
The remainder is 70 after subtracting 0 from 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 6:
The number 86 fits into 700 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1160.8
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.

Advancing to step 7:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1160.81
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 8:
When dividing 340 by 86, we get 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 1160.813
If we subtract 258 from 340, we 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 9:
When dividing 820 by 86, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1160.8139
Deduct 774 from 820 and we're left 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.

Going ahead to step 10:
460 divided by 86 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1160.81395
If we subtract 430 from 460, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1160.813953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
420 divided by 86 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 1160.8139534
If we take 344 away from 420, we end up 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.

Moving on to step 13:
86 can be fit into 760 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 1160.81395348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 1160.81395348 and a remainder of 7.2e-08.
