Let's divide 904881 by 86
The aim is to understand the frequency of 86 in 904881.

On to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 86

On to step 2:
86 can be fit into 90 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 90 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 86

Going ahead to step 3:
86 can be fit into 44 0 times, resulting in a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 44, we get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 86

Let's proceed to step 4:
When dividing 448 by 86, we get 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we take 430 away from 448, we end up with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 86

Moving on to step 5:
The number 86 fits into 188 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1052.0
The remainder is 16 after subtracting 172 from 188.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 86

On to step 6:
When dividing 161 by 86, we get 1 with a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 10521.0
The remainder is 75 after subtracting 86 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
The number 86 fits into 750 8 times, leaving a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 10521.8
Deduct 688 from 750 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
If we divide 620 by 86, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 10521.87
If we take 602 away from 620, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
If we divide 180 by 86, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 10521.872
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 10521.872
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
When dividing 800 by 86, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 10521.87209
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
When dividing 260 by 86, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 10521.872093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
If we divide 20 by 86, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10521.872093
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 10521.87209302
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 10521.87209302 with a remaining 2.8e-08.
