977987 divided by 20 
We want to figure out the number of times 977987 can be divided by 20.

Moving on to step 1:
The number 20 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 20

Let's proceed 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
The remainder is 17 after subtracting 80 from 97.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 20

Let's proceed to step 3:
20 goes into 177 8 times with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 160 away from 177, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 20

Going ahead to step 4:
179 divided by 20 is 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 488.0
Deduct 160 from 179 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 20

Step 5:
The number 20 fits into 198 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 4889.0
Subtract 180 from 198 to get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 20

On to step 6:
The number 20 fits into 187 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 48899.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 20 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 48899.3
The remainder is 10 after subtracting 60 from 70.
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:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 48899.35
Subtract 100 from 100 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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48899.35
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48899.35
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.

Our division results in 48899.35 with a remaining 0.0.
