323783 divided by 86 
The aim is to understand the frequency of 86 in 323783.

On to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 86

On to step 2:
If we divide 32 by 86, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 86

Moving on to step 3:
When dividing 323 by 86, we get 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 258 from 323 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 86

Step 4:
86 can be fit into 657 7 times, resulting in a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 602 from 657 leaves us with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 86

Moving on to step 5:
558 divided by 86 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we subtract 516 from 558, we get 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 86

Going ahead to step 6:
86 can be fit into 423 4 times, resulting in a remainder of 79.
The number 4 becomes the next digit in our result. 
Result so far: 3764.0
Subtracting 344 from 423 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 7:
If we divide 790 by 86, we get 9 and a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 3764.9
If we take 774 away from 790, we end up 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 8:
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: 3764.91
Deduct 86 from 160 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
When dividing 740 by 86, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 3764.918
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.

Moving on to step 10:
The number 86 fits into 520 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3764.9186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
If we divide 40 by 86, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3764.9186
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
86 goes into 400 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 3764.918604
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.

Let's proceed to step 13:
86 can be fit into 560 6 times, resulting in a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 3764.9186046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
86 goes into 440 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3764.91860465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3764.91860465, with a leftover of 1e-08.
