We look at the division of 189999 by 50 
We're looking to find how many times 50 goes into 189999.

Step 1:
1 divided by 50 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 50

Moving on to step 2:
50 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 50

Let's proceed to step 3:
When dividing 189 by 50, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 150 from 189, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 50

Going ahead to step 4:
50 can be fit into 399 7 times, resulting in a remainder of 49.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 350 from 399, we get 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 50

Let's proceed to step 5:
50 can be fit into 499 9 times, resulting in a remainder of 49.
The next digit of our result is 9. 
Result so far: 379.0
Deduct 450 from 499 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 50

Step 6:
499 divided by 50 is 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 3799.0
Subtracting 450 from 499 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
50 can be fit into 490 9 times, resulting in a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 3799.9
The remainder is 40 after subtracting 450 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
The number 50 fits into 400 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3799.98
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3799.98
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3799.98
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3799.98, with a leftover of 0.0.
