77837868 ÷ 503 
We want to figure out the number of times 77837868 can be divided by 503.

Step 1:
When dividing 7 by 503, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 503

On to step 2:
When dividing 77 by 503, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 503

Going ahead to step 3:
778 divided by 503 is 1 with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 275 after subtracting 503 from 778.
Bring next digit (3) of the dividend behind the 275 and repeat the process: 2753 / 503

Going ahead to step 4:
If we divide 2753 by 503, we get 5 and a remainder of 238.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2515 from 2753 to get 238.
Fetch the next digit (7) from the dividend, attach it to 238 and continue: 2387 / 503

Moving on to step 5:
2387 divided by 503 is 4 with a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Subtracting 2012 from 2387 leaves us with 375.
Include the next digit (8) from the dividend after 375, then repeat: 3758 / 503

Going ahead to step 6:
503 goes into 3758 7 times with a remainder of 237.
The next digit of our result is 7. 
Result so far: 1547.0
If we subtract 3521 from 3758, we get 237.
Include the next digit (6) from the dividend after 237, then repeat: 2376 / 503

Let's proceed to step 7:
2376 divided by 503 is 4 with a remainder of 364.
The number 4 becomes the next digit in our result. 
Result so far: 15474.0
The remainder is 364 after subtracting 2012 from 2376.
Append the next digit (8) from the dividend to 364 and continue with: 3648 / 503

On to step 8:
503 goes into 3648 7 times with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 154747.0
Subtract 3521 from 3648 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
503 goes into 1270 2 times with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 154747.2
Deduct 1006 from 1270 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 10:
503 goes into 2640 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 154747.25
If we take 2515 away from 2640, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
1250 divided by 503 is 2 with a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 154747.252
The remainder is 244 after subtracting 1006 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 12:
If we divide 2440 by 503, we get 4 and a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 154747.2524
Subtracting 2012 from 2440 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 13:
503 goes into 4280 8 times with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 154747.25248
The remainder is 256 after subtracting 4024 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 14:
503 can be fit into 2560 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 154747.252485
If we take 2515 away from 2560, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
503 goes into 450 0 times with a remainder of 450.
The next digit of our result is 0. 
Result so far: 154747.252485
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 16:
503 can be fit into 4500 8 times, resulting in a remainder of 476.
The next digit of our result is 8. 
Result so far: 154747.25248508
Deduct 4024 from 4500 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The quotient of the division is 154747.25248508, and the remainder is 4.76e-07.
