77683848 ÷ 504 
Our goal is to divide 77683848 by 504.

On to step 1:
The number 504 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 504

Let's proceed to step 2:
77 divided by 504 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 504

On to step 3:
If we divide 776 by 504, we get 1 and a remainder of 272.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 272 after subtracting 504 from 776.
Include the next digit (8) from the dividend after 272, then repeat: 2728 / 504

Let's proceed to step 4:
504 goes into 2728 5 times with a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2520 from 2728 leaves us with 208.
Bring next digit (3) of the dividend behind the 208 and repeat the process: 2083 / 504

Going ahead to step 5:
2083 divided by 504 is 4 with a remainder of 67.
The next digit of our result is 4. 
Result so far: 154.0
The remainder is 67 after subtracting 2016 from 2083.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 504

Step 6:
When dividing 678 by 504, we get 1 with a remainder of 174.
Record the quotient 1 as the next digit in the result. 
Result so far: 1541.0
If we take 504 away from 678, we end up with 174.
Take the next digit (4) from the dividend and append it to 174, then repeat: 1744 / 504

Let's proceed to step 7:
The number 504 fits into 1744 3 times, leaving a remainder of 232.
Use 3 as the next digit of our solution. 
Result so far: 15413.0
Subtract 1512 from 1744 to get 232.
Take the next digit (8) from the dividend and append it to 232, then repeat: 2328 / 504

Let's proceed to step 8:
The number 504 fits into 2328 4 times, leaving a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 154134.0
Deduct 2016 from 2328 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 9:
3120 divided by 504 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 154134.6
If we subtract 3024 from 3120, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 10:
If we divide 960 by 504, we get 1 and a remainder of 456.
The number 1 becomes the next digit in our result. 
Result so far: 154134.61
Deduct 504 from 960 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 11:
504 goes into 4560 9 times with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 154134.619
If we subtract 4536 from 4560, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
504 can be fit into 240 0 times, resulting in a remainder of 240.
The next digit of our result is 0. 
Result so far: 154134.619
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
504 goes into 2400 4 times with a remainder of 384.
Write down 4 as next digit of the result. 
Result so far: 154134.61904
Subtract 2016 from 2400 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 14:
If we divide 3840 by 504, we get 7 and a remainder of 312.
Write down 7 as next digit of the result. 
Result so far: 154134.619047
If we take 3528 away from 3840, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
504 can be fit into 3120 6 times, resulting in a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 154134.6190476
Deduct 3024 from 3120 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
The number 504 fits into 960 1 times, leaving a remainder of 456.
The next digit of our result is 1. 
Result so far: 154134.61904761
Deduct 504 from 960 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

In conclusion, the division gives 154134.61904761 with a balance of 4.56e-07.
