Let's divide 223940 by 17
We want to figure out the number of times 223940 can be divided by 17.

Step 1:
17 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 17

Advancing to step 2:
The number 17 fits into 22 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
If we take 17 away from 22, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 17

Moving on to step 3:
The number 17 fits into 53 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 51 from 53 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 17

Advancing to step 4:
17 goes into 29 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 17 from 29 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 17

Advancing to step 5:
124 divided by 17 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1317.0
If we subtract 119 from 124, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 17

Moving on to step 6:
17 can be fit into 50 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 13172.0
Subtract 34 from 50 to 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.

Let's proceed to step 7:
If we divide 160 by 17, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 13172.9
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 17, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 13172.94
Subtract 68 from 70 to 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:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 13172.941
If we subtract 17 from 20, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed 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: 13172.9411
Subtracting 17 from 30 leaves us 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 final result is 13172.9411 with a remainder of 0.00013.
