964373 divided by 86 
The aim is to understand the frequency of 86 in 964373.

Moving on to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 86

Moving on to step 2:
The number 86 fits into 96 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 96 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 86

Moving on to step 3:
86 goes into 104 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 86 from 104 leaves us with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 86

Let's proceed to step 4:
86 can be fit into 183 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 172 from 183, we get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 86

Step 5:
86 goes into 117 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1121.0
Deduct 86 from 117 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 86

On to step 6:
313 divided by 86 is 3 with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 11213.0
Subtracting 258 from 313 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
The number 86 fits into 550 6 times, leaving a remainder of 34.
The next digit of our result is 6. 
Result so far: 11213.6
Subtracting 516 from 550 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:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 11213.63
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
When dividing 820 by 86, we get 9 with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 11213.639
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.

Let's proceed to step 10:
460 divided by 86 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11213.6395
Deduct 430 from 460 and we're left 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.

Let's proceed to step 11:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 11213.63953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 11213.639534
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.

Going ahead to step 13:
When dividing 760 by 86, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 11213.6395348
Subtracting 688 from 760 leaves us 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.

On to step 14:
If we divide 720 by 86, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 11213.63953488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 11213.63953488 and a remainder of 3.2e-08.
