We're dividing 771136 by 18 
The aim is to understand the frequency of 18 in 771136.

Moving on to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 18

Moving on to step 2:
18 goes into 77 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we take 72 away from 77, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 18

Let's proceed to step 3:
When dividing 51 by 18, we get 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 36 from 51 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 18

Step 4:
151 divided by 18 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 428.0
If we take 144 away from 151, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 18

On to step 5:
If we divide 73 by 18, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4284.0
Subtracting 72 from 73 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 18

Moving on to step 6:
18 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 42840.0
The remainder is 16 after subtracting 0 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
160 divided by 18 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 42840.8
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 42840.88
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 42840.88, with a leftover of 0.016.
