We're dividing 65879354 by 503 
We want to divide 65879354 by 503.

Moving on to step 1:
503 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 503

Moving on to step 2:
If we divide 65 by 503, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 503

On to step 3:
503 goes into 658 1 times with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 503 from 658 and we're left with 155.
Grab the next digit (7) from the dividend, add it to 155, then carry on: 1557 / 503

Step 4:
If we divide 1557 by 503, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1509 from 1557 to get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 503

Advancing to step 5:
The number 503 fits into 489 0 times, leaving a remainder of 489.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 489 leaves us with 489.
Grab the next digit (3) from the dividend, add it to 489, then carry on: 4893 / 503

On to step 6:
503 goes into 4893 9 times with a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 1309.0
If we take 4527 away from 4893, we end up with 366.
Bring next digit (5) of the dividend behind the 366 and repeat the process: 3665 / 503

Step 7:
If we divide 3665 by 503, we get 7 and a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 13097.0
Subtract 3521 from 3665 to get 144.
Take the next digit (4) from the dividend and append it to 144, then repeat: 1444 / 503

Going ahead to step 8:
503 can be fit into 1444 2 times, resulting in a remainder of 438.
Write down 2 as next digit of the result. 
Result so far: 130972.0
Subtracting 1006 from 1444 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 9:
The number 503 fits into 4380 8 times, leaving a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 130972.8
If we subtract 4024 from 4380, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 10:
503 goes into 3560 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 130972.87
Subtracting 3521 from 3560 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 503 fits into 390 0 times, leaving a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 130972.87
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 12:
3900 divided by 503 is 7 with a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 130972.8707
Deduct 3521 from 3900 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 13:
503 can be fit into 3790 7 times, resulting in a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 130972.87077
Subtract 3521 from 3790 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 130972.87077, with a leftover of 0.000269.
