375917 ÷ 18 
The aim is to understand the frequency of 18 in 375917.

On to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 18

Moving on to step 2:
If we divide 37 by 18, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 36 from 37 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 18

Moving on to step 3:
When dividing 15 by 18, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 18

Let's proceed to step 4:
When dividing 159 by 18, we get 8 with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Subtracting 144 from 159 leaves us with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 18

Advancing to step 5:
18 can be fit into 151 8 times, resulting in a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 2088.0
Subtract 144 from 151 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 18

Moving on to step 6:
77 divided by 18 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 20884.0
Deduct 72 from 77 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
18 can be fit into 50 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 20884.2
Subtracting 36 from 50 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 20884.27
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 18 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 20884.277
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 20884.277 with a balance of 0.0014.
