776045 divided by 18 
The aim is to understand the frequency of 18 in 776045.

On to step 1:
18 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 18

Going ahead to step 2:
The number 18 fits into 77 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 72 away from 77, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 18

On to step 3:
18 goes into 56 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we subtract 54 from 56, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 18

Let's proceed to step 4:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 431.0
Subtract 18 from 20 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 18

Advancing to step 5:
When dividing 24 by 18, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 4311.0
If we subtract 18 from 24, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 18

Step 6:
The number 18 fits into 65 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 43113.0
If we take 54 away from 65, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 18, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 43113.6
If we take 108 away from 110, we end up 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.

Let's proceed to step 8:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 43113.61
Subtracting 18 from 20 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.

Advancing to step 9:
18 can be fit into 20 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 43113.611
Subtracting 18 from 20 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.

After the division, we end up with 43113.611 and a remainder of 0.0002.
