We're dividing 189720 by 5 
We want to figure out the number of times 189720 can be divided by 5.

Moving on to step 1:
5 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 5

Advancing to step 2:
If we divide 18 by 5, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 15 from 18, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 5

Step 3:
39 divided by 5 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 35 away from 39, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 5

Let's proceed to step 4:
The number 5 fits into 47 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 379.0
Subtracting 45 from 47 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 5

Step 5:
If we divide 22 by 5, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3794.0
If we take 20 away from 22, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 5

Let's proceed to step 6:
5 can be fit into 20 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 37944.0
Subtracting 20 from 20 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 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37944.0
Deduct 0 from 0 and we're left 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.

Going ahead to step 8:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37944.0
The remainder is 0 after subtracting 0 from 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 37944.0, with a leftover of 0.0.
