We're dividing 50878384 by 903 
Our goal is to divide 50878384 by 903.

Advancing to step 1:
903 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 903

Let's proceed to step 2:
50 divided by 903 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 903

Going ahead to step 3:
When dividing 508 by 903, we get 0 with a remainder of 508.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 508 leaves us with 508.
Take the next digit (7) from the dividend and append it to 508, then repeat: 5087 / 903

Let's proceed to step 4:
903 can be fit into 5087 5 times, resulting in a remainder of 572.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4515 from 5087 and we're left with 572.
Append the next digit (8) from the dividend to 572 and continue with: 5728 / 903

Moving on to step 5:
5728 divided by 903 is 6 with a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtracting 5418 from 5728 leaves us with 310.
Include the next digit (3) from the dividend after 310, then repeat: 3103 / 903

Step 6:
903 goes into 3103 3 times with a remainder of 394.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
If we subtract 2709 from 3103, we get 394.
Bring next digit (8) of the dividend behind the 394 and repeat the process: 3948 / 903

Let's proceed to step 7:
If we divide 3948 by 903, we get 4 and a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 5634.0
If we take 3612 away from 3948, we end up with 336.
Include the next digit (4) from the dividend after 336, then repeat: 3364 / 903

Let's proceed to step 8:
If we divide 3364 by 903, we get 3 and a remainder of 655.
The next digit of our result is 3. 
Result so far: 56343.0
The remainder is 655 after subtracting 2709 from 3364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 9:
If we divide 6550 by 903, we get 7 and a remainder of 229.
Use 7 as the next digit of our solution. 
Result so far: 56343.7
If we subtract 6321 from 6550, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 10:
903 can be fit into 2290 2 times, resulting in a remainder of 484.
Put 2 as the next digit of the answer. 
Result so far: 56343.72
Subtract 1806 from 2290 to get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 11:
903 goes into 4840 5 times with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 56343.725
If we take 4515 away from 4840, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
903 goes into 3250 3 times with a remainder of 541.
Record the quotient 3 as the next digit in the result. 
Result so far: 56343.7253
Subtracting 2709 from 3250 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 13:
903 can be fit into 5410 5 times, resulting in a remainder of 895.
Put 5 as the next digit of the answer. 
Result so far: 56343.72535
Deduct 4515 from 5410 and we're left with 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

On to step 14:
The number 903 fits into 8950 9 times, leaving a remainder of 823.
Put 9 as the next digit of the answer. 
Result so far: 56343.725359
Subtract 8127 from 8950 to get 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8230, and continue the process.

Advancing to step 15:
903 goes into 8230 9 times with a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 56343.7253599
Deduct 8127 from 8230 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The final result is 56343.7253599 with a remainder of 1.03e-06.
