789800 divided by 20 
We're looking to find how many times 20 goes into 789800.

Let's proceed to step 1:
20 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Step 2:
The number 20 fits into 78 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 60 from 78 and we're left with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 20

Advancing to step 3:
20 can be fit into 189 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 180 from 189 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 20

Moving on to step 4:
20 can be fit into 98 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
Subtracting 80 from 98 leaves us with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 20

Going ahead to step 5:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 3949.0
Subtract 180 from 180 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 20

Let's proceed to step 6:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39490.0
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.

Moving on to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39490.0
Subtract 0 from 0 to 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39490.0
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.

The final outcome is 39490.0, with a leftover of 0.0.
