Let's divide 904712 by 86
The aim is to understand the frequency of 86 in 904712.

On to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 86

Advancing to step 2:
90 divided by 86 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 86 away from 90, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 86

On to step 3:
If we divide 44 by 86, we get 0 and a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 44, we end up with 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 86

Step 4:
86 goes into 447 5 times with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 17 after subtracting 430 from 447.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 86

Going ahead to step 5:
If we divide 171 by 86, we get 1 and a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
If we subtract 86 from 171, we get 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 86

Let's proceed to step 6:
86 goes into 852 9 times with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 10519.0
Subtracting 774 from 852 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 7:
When dividing 780 by 86, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 10519.9
Subtracting 774 from 780 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
86 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 10519.9
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
When dividing 600 by 86, we get 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 10519.906
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 10519.9069
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
If we divide 660 by 86, we get 7 and a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 10519.90697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
86 can be fit into 580 6 times, resulting in a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 10519.906976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
640 divided by 86 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 10519.9069767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 10519.90697674
Subtracting 344 from 380 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.

The final result is 10519.90697674 with a remainder of 3.6e-08.
