838066 ÷ 86 
The aim is to understand the frequency of 86 in 838066.

Step 1:
86 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 86

Step 2:
86 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 86

Let's proceed to step 3:
838 divided by 86 is 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 64 after subtracting 774 from 838.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 86

Let's proceed to step 4:
86 goes into 640 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 602 from 640 and we're left with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 86

Going ahead to step 5:
When dividing 386 by 86, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
Subtracting 344 from 386 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 86

Step 6:
If we divide 426 by 86, we get 4 and a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 9744.0
If we take 344 away from 426, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 7:
820 divided by 86 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 9744.9
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 9744.95
Subtracting 430 from 460 leaves us 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.

Step 9:
300 divided by 86 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9744.953
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.

Let's proceed to step 10:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 9744.9534
Deduct 344 from 420 and we're left 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.

On to step 11:
When dividing 760 by 86, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 9744.95348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9744.953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 9744.953488, and the remainder is 3.2e-06.
