We're dividing 86023154 by 905 
The aim is to understand the frequency of 905 in 86023154.

On to step 1:
8 divided by 905 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 905

Advancing to step 2:
The number 905 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 905

Going ahead to step 3:
When dividing 860 by 905, we get 0 with a remainder of 860.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 860, we end up with 860.
Fetch the next digit (2) from the dividend, attach it to 860 and continue: 8602 / 905

On to step 4:
The number 905 fits into 8602 9 times, leaving a remainder of 457.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8145 away from 8602, we end up with 457.
Grab the next digit (3) from the dividend, add it to 457, then carry on: 4573 / 905

On to step 5:
When dividing 4573 by 905, we get 5 with a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 4525 from 4573 to get 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 905

Advancing to step 6:
If we divide 481 by 905, we get 0 and a remainder of 481.
Use 0 as the next digit of our solution. 
Result so far: 950.0
If we take 0 away from 481, we end up with 481.
Fetch the next digit (5) from the dividend, attach it to 481 and continue: 4815 / 905

Step 7:
When dividing 4815 by 905, we get 5 with a remainder of 290.
The next digit of our result is 5. 
Result so far: 9505.0
Subtracting 4525 from 4815 leaves us with 290.
Take the next digit (4) from the dividend and append it to 290, then repeat: 2904 / 905

Moving on to step 8:
When dividing 2904 by 905, we get 3 with a remainder of 189.
The number 3 becomes the next digit in our result. 
Result so far: 95053.0
If we take 2715 away from 2904, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 9:
1890 divided by 905 is 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 95053.2
If we subtract 1810 from 1890, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
800 divided by 905 is 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 95053.2
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
905 goes into 8000 8 times with a remainder of 760.
The number 8 becomes the next digit in our result. 
Result so far: 95053.208
If we subtract 7240 from 8000, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 12:
When dividing 7600 by 905, we get 8 with a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 95053.2088
If we subtract 7240 from 7600, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 95053.2088 with a remaining 0.0036.
