77489544 ÷ 505 
Let's see how many times 505 fits into 77489544.

Moving on to step 1:
The number 505 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 505

Moving on to step 2:
If we divide 77 by 505, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 505

Step 3:
505 can be fit into 774 1 times, resulting in a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 505 from 774, we get 269.
Take the next digit (8) from the dividend and append it to 269, then repeat: 2698 / 505

Moving on to step 4:
When dividing 2698 by 505, we get 5 with a remainder of 173.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2525 away from 2698, we end up with 173.
Take the next digit (9) from the dividend and append it to 173, then repeat: 1739 / 505

Advancing to step 5:
When dividing 1739 by 505, we get 3 with a remainder of 224.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Subtract 1515 from 1739 to get 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 505

Step 6:
2245 divided by 505 is 4 with a remainder of 225.
Put 4 as the next digit of the answer. 
Result so far: 1534.0
The remainder is 225 after subtracting 2020 from 2245.
Fetch the next digit (4) from the dividend, attach it to 225 and continue: 2254 / 505

Moving on to step 7:
If we divide 2254 by 505, we get 4 and a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 15344.0
Deduct 2020 from 2254 and we're left with 234.
Fetch the next digit (4) from the dividend, attach it to 234 and continue: 2344 / 505

On to step 8:
505 goes into 2344 4 times with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 153444.0
Subtract 2020 from 2344 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
3240 divided by 505 is 6 with a remainder of 210.
The next digit of our result is 6. 
Result so far: 153444.6
Deduct 3030 from 3240 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
2100 divided by 505 is 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 153444.64
If we take 2020 away from 2100, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 505 fits into 800 1 times, leaving a remainder of 295.
Use 1 as the next digit of our solution. 
Result so far: 153444.641
If we take 505 away from 800, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 12:
2950 divided by 505 is 5 with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 153444.6415
Subtract 2525 from 2950 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 13:
If we divide 4250 by 505, we get 8 and a remainder of 210.
Put 8 as the next digit of the answer. 
Result so far: 153444.64158
Subtract 4040 from 4250 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
The number 505 fits into 2100 4 times, leaving a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 153444.641584
Subtract 2020 from 2100 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
505 goes into 800 1 times with a remainder of 295.
The next digit of our result is 1. 
Result so far: 153444.6415841
The remainder is 295 after subtracting 505 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 16:
If we divide 2950 by 505, we get 5 and a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 153444.64158415
Subtracting 2525 from 2950 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The final result is 153444.64158415 with a remainder of 4.25e-07.
