We're dividing 977777 by 20 
Our goal is to divide 977777 by 20.

Step 1:
9 divided by 20 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 20

Let's proceed to step 2:
When dividing 97 by 20, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 97, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 20

Advancing to step 3:
177 divided by 20 is 8 with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 160 away from 177, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 20

Let's proceed to step 4:
20 can be fit into 177 8 times, resulting in a remainder of 17.
The next digit of our result is 8. 
Result so far: 488.0
Subtracting 160 from 177 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 20

Step 5:
When dividing 177 by 20, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 4888.0
Subtracting 160 from 177 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 20

On to step 6:
When dividing 177 by 20, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 48888.0
Deduct 160 from 177 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48888.8
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 48888.85
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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48888.85
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 48888.85
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.

After the division, we end up with 48888.85 and a remainder of 0.0.
