783926 ÷ 86 
The aim is to understand the frequency of 86 in 783926.

Let's proceed to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 86

On to step 2:
If we divide 78 by 86, we get 0 and a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 86

Moving on to step 3:
When dividing 783 by 86, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 774 from 783, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 86

Step 4:
When dividing 99 by 86, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 86 from 99, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 86

Advancing to step 5:
The number 86 fits into 132 1 times, leaving a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 911.0
If we take 86 away from 132, we end up with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 86

Moving on to step 6:
86 goes into 466 5 times with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 9115.0
The remainder is 36 after subtracting 430 from 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
86 goes into 360 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9115.4
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
The next digit of our result is 1. 
Result so far: 9115.41
If we take 86 away from 160, we end up 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.

Advancing 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: 9115.418
The remainder is 52 after subtracting 688 from 740.
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:
When dividing 520 by 86, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9115.4186
If we take 516 away from 520, we end up 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.

Let's proceed to step 11:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9115.4186
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.

Advancing to step 12:
86 goes into 400 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 9115.418604
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 13:
When dividing 560 by 86, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 9115.4186046
Deduct 516 from 560 and we're left 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.

Moving on to step 14:
When dividing 440 by 86, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 9115.41860465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 9115.41860465 with a remaining 1e-08.
