We divide 697455 by 86
The aim is to understand the frequency of 86 in 697455.

On to step 1:
When dividing 6 by 86, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 86

Advancing to step 2:
86 goes into 69 0 times with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 69 leaves us with 69.
Fetch the next digit (7) from the dividend, attach it to 69 and continue: 697 / 86

Moving on to step 3:
If we divide 697 by 86, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 9 after subtracting 688 from 697.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 86

Going ahead to step 4:
When dividing 94 by 86, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 86 from 94 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 86

Let's proceed to step 5:
When dividing 85 by 86, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 810.0
Subtracting 0 from 85 leaves us with 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 86

Let's proceed to step 6:
855 divided by 86 is 9 with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 8109.0
If we take 774 away from 855, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
The number 86 fits into 810 9 times, leaving a remainder of 36.
The next digit of our result is 9. 
Result so far: 8109.9
Subtracting 774 from 810 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
If we divide 360 by 86, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 8109.94
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
86 can be fit into 160 1 times, resulting in a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 8109.941
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
The number 86 fits into 740 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 8109.9418
Deduct 688 from 740 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
When dividing 520 by 86, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 8109.94186
Subtract 516 from 520 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 86, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8109.94186
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 8109.9418604
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 8109.94186046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 8109.94186046 and a remainder of 4.4e-08.
