Let's divide 378550 by 20
We're looking to find how many times 20 goes into 378550.

Going ahead to step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 20

Let's proceed to step 2:
The number 20 fits into 37 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 37 to get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 20

Let's proceed to step 3:
If we divide 178 by 20, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 160 from 178 leaves us with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Step 4:
The number 20 fits into 185 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 189.0
If we take 180 away from 185, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 20

Advancing to step 5:
When dividing 55 by 20, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 1892.0
If we take 40 away from 55, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 20

Moving on to step 6:
20 goes into 150 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 18927.0
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18927.5
The remainder is 0 after subtracting 100 from 100.
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 18927.5
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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18927.5
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.

The quotient of the division is 18927.5, and the remainder is 0.0.
