53983460 ÷ 503 
We're looking to find how many times 503 goes into 53983460.

Going ahead to step 1:
5 divided by 503 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 503

On to step 2:
When dividing 53 by 503, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 503

Step 3:
If we divide 539 by 503, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 503 from 539 and we're left with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 503

Step 4:
503 goes into 368 0 times with a remainder of 368.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 368, we end up with 368.
Take the next digit (3) from the dividend and append it to 368, then repeat: 3683 / 503

Let's proceed to step 5:
The number 503 fits into 3683 7 times, leaving a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
If we subtract 3521 from 3683, we get 162.
Grab the next digit (4) from the dividend, add it to 162, then carry on: 1624 / 503

On to step 6:
1624 divided by 503 is 3 with a remainder of 115.
The next digit of our result is 3. 
Result so far: 1073.0
If we subtract 1509 from 1624, we get 115.
Take the next digit (6) from the dividend and append it to 115, then repeat: 1156 / 503

Step 7:
The number 503 fits into 1156 2 times, leaving a remainder of 150.
The next digit of our result is 2. 
Result so far: 10732.0
Subtract 1006 from 1156 to get 150.
Include the next digit (0) from the dividend after 150, then repeat: 1500 / 503

Going ahead to step 8:
503 goes into 1500 2 times with a remainder of 494.
The number 2 becomes the next digit in our result. 
Result so far: 107322.0
Subtracting 1006 from 1500 leaves us with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 9:
If we divide 4940 by 503, we get 9 and a remainder of 413.
Use 9 as the next digit of our solution. 
Result so far: 107322.9
If we take 4527 away from 4940, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 10:
503 can be fit into 4130 8 times, resulting in a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 107322.98
Deduct 4024 from 4130 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
503 can be fit into 1060 2 times, resulting in a remainder of 54.
The next digit of our result is 2. 
Result so far: 107322.982
Subtracting 1006 from 1060 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
When dividing 540 by 503, we get 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 107322.9821
If we take 503 away from 540, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
If we divide 370 by 503, we get 0 and a remainder of 370.
Record the quotient 0 as the next digit in the result. 
Result so far: 107322.9821
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 14:
The number 503 fits into 3700 7 times, leaving a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 107322.982107
The remainder is 179 after subtracting 3521 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 15:
1790 divided by 503 is 3 with a remainder of 281.
Put 3 as the next digit of the answer. 
Result so far: 107322.9821073
The remainder is 281 after subtracting 1509 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 16:
If we divide 2810 by 503, we get 5 and a remainder of 295.
The next digit of our result is 5. 
Result so far: 107322.98210735
The remainder is 295 after subtracting 2515 from 2810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

The quotient of the division is 107322.98210735, and the remainder is 2.95e-07.
