789977 ÷ 50 
Our goal is to divide 789977 by 50.

Advancing to step 1:
The number 50 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 50

Moving on to step 2:
50 goes into 78 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
If we take 50 away from 78, we end up with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 50

Going ahead to step 3:
289 divided by 50 is 5 with a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 250 from 289 and we're left with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 50

Moving on to step 4:
The number 50 fits into 399 7 times, leaving a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we take 350 away from 399, we end up with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 50

Let's proceed to step 5:
497 divided by 50 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 1579.0
Subtracting 450 from 497 leaves us with 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 50

On to step 6:
50 goes into 477 9 times with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 15799.0
Deduct 450 from 477 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
50 can be fit into 270 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 15799.5
If we subtract 250 from 270, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 50, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 15799.54
Subtracting 200 from 200 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:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15799.54
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:
50 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15799.54
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 15799.54 with a remainder of 0.0.
