189388 ÷ 20 
We want to figure out the number of times 189388 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 20

Step 2:
20 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 20

Let's proceed to step 3:
189 divided by 20 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 180 from 189, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 20

Advancing to step 4:
93 divided by 20 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 80 from 93 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 20

Advancing to step 5:
138 divided by 20 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 946.0
The remainder is 18 after subtracting 120 from 138.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 20

Step 6:
20 can be fit into 188 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 9469.0
If we take 180 away from 188, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
80 divided by 20 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 9469.4
Subtracting 80 from 80 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.

Advancing to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9469.4
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9469.4
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.

After the division, we end up with 9469.4 and a remainder of 0.0.
