978089 divided by 20 
Our goal is to divide 978089 by 20.

Advancing to step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 20

Advancing to step 2:
When dividing 97 by 20, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 97 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Step 3:
If we divide 178 by 20, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 160 from 178 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 20

On to step 4:
180 divided by 20 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 489.0
If we subtract 180 from 180, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 20

Moving on to step 5:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 4890.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 20

Going ahead to step 6:
20 can be fit into 89 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 48904.0
If we take 80 away from 89, we end up 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.

Going ahead to step 7:
20 goes into 90 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 48904.4
Subtracting 80 from 90 leaves us 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.

Step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 48904.45
If we subtract 100 from 100, 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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48904.45
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.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48904.45
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.

The quotient of the division is 48904.45, and the remainder is 0.0.
