We look at the division of 90319927 by 918 
The aim is to understand the frequency of 918 in 90319927.

Advancing to step 1:
If we divide 9 by 918, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 918

On to step 2:
If we divide 90 by 918, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 918

Advancing to step 3:
903 divided by 918 is 0 with a remainder of 903.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 903 after subtracting 0 from 903.
Include the next digit (1) from the dividend after 903, then repeat: 9031 / 918

Moving on to step 4:
918 can be fit into 9031 9 times, resulting in a remainder of 769.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 769 after subtracting 8262 from 9031.
Include the next digit (9) from the dividend after 769, then repeat: 7699 / 918

On to step 5:
When dividing 7699 by 918, we get 8 with a remainder of 355.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we take 7344 away from 7699, we end up with 355.
Append the next digit (9) from the dividend to 355 and continue with: 3559 / 918

Step 6:
When dividing 3559 by 918, we get 3 with a remainder of 805.
Record the quotient 3 as the next digit in the result. 
Result so far: 983.0
Deduct 2754 from 3559 and we're left with 805.
Append the next digit (2) from the dividend to 805 and continue with: 8052 / 918

Step 7:
When dividing 8052 by 918, we get 8 with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 9838.0
Subtract 7344 from 8052 to get 708.
Append the next digit (7) from the dividend to 708 and continue with: 7087 / 918

Moving on to step 8:
918 goes into 7087 7 times with a remainder of 661.
Use 7 as the next digit of our solution. 
Result so far: 98387.0
Subtract 6426 from 7087 to get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Let's proceed to step 9:
The number 918 fits into 6610 7 times, leaving a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 98387.7
If we subtract 6426 from 6610, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 10:
1840 divided by 918 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 98387.72
If we take 1836 away from 1840, 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.

Moving on to step 11:
40 divided by 918 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 98387.72
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 918 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 98387.72
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 98387.72 with a remaining 0.004.
