18006351 ÷ 17 
The aim is to understand the frequency of 17 in 18006351.

Moving on to step 1:
When dividing 1 by 17, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 17

Going ahead to step 2:
17 goes into 18 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 17 from 18, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 17

Let's proceed to step 3:
10 divided by 17 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 17

Advancing to step 4:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 85 away from 100, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 17

Going ahead to step 5:
156 divided by 17 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1059.0
If we take 153 away from 156, we end up with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 17

Let's proceed to step 6:
When dividing 33 by 17, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 10591.0
Subtract 17 from 33 to get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 17

Advancing to step 7:
The number 17 fits into 165 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 105919.0
Deduct 153 from 165 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 17

On to step 8:
17 can be fit into 121 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1059197.0
If we subtract 119 from 121, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
17 goes into 20 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1059197.1
Subtracting 17 from 20 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
If we divide 30 by 17, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 1059197.11
If we take 17 away from 30, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 1059197.11, and the remainder is 0.013.
