77729975 ÷ 50 
Let's see how many times 50 fits into 77729975.

Step 1:
If we divide 7 by 50, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 50

Step 2:
50 can be fit into 77 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 50 from 77, we get 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 50

On to step 3:
277 divided by 50 is 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 250 from 277 and we're left with 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 50

Advancing to step 4:
272 divided by 50 is 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
The remainder is 22 after subtracting 250 from 272.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 50

Step 5:
50 goes into 229 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 1554.0
Deduct 200 from 229 and we're left with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 50

On to step 6:
50 goes into 299 5 times with a remainder of 49.
The next digit of our result is 5. 
Result so far: 15545.0
Subtract 250 from 299 to get 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 50

Moving on to step 7:
If we divide 497 by 50, we get 9 and a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 155459.0
If we take 450 away from 497, we end up with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 50

Advancing to step 8:
50 goes into 475 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 1554599.0
If we take 450 away from 475, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
50 goes into 250 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1554599.5
Deduct 250 from 250 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.

Step 10:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1554599.5
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.

Let's proceed to step 11:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1554599.5
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.

In conclusion, the division gives 1554599.5 with a balance of 0.0.
