We're dividing 719890 by 20 
We're looking to find how many times 20 goes into 719890.

Step 1:
7 divided by 20 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 20

Advancing to step 2:
If we divide 71 by 20, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 60 from 71, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 20

Step 3:
20 goes into 119 5 times with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we subtract 100 from 119, we get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 20

On to step 4:
If we divide 198 by 20, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 359.0
Subtracting 180 from 198 leaves us with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 20

Moving on to step 5:
189 divided by 20 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 3599.0
Subtract 180 from 189 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 20

Advancing to step 6:
If we divide 90 by 20, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 35994.0
Subtract 80 from 90 to 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.

Moving on to step 7:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 35994.5
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: 35994.5
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35994.5
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 final outcome is 35994.5, with a leftover of 0.0.
