789289 divided by 20 
Let's see how many times 20 fits into 789289.

Advancing to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Going ahead to step 2:
When dividing 78 by 20, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
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

Going ahead to step 3:
If we divide 189 by 20, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
The remainder is 9 after subtracting 180 from 189.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 20

Advancing to step 4:
20 can be fit into 92 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Subtracting 80 from 92 leaves us with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 20

Advancing to step 5:
If we divide 128 by 20, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 3946.0
Subtracting 120 from 128 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

Advancing to step 6:
If we divide 89 by 20, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 39464.0
Deduct 80 from 89 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
20 goes into 90 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 39464.4
If we take 80 away from 90, we end up with 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 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39464.45
Subtracting 100 from 100 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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39464.45
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39464.45
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 result is 39464.45 with a remainder of 0.0.
