Let's divide 51403322 by 903
Our goal is to divide 51403322 by 903.

Step 1:
5 divided by 903 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 903

On to step 2:
If we divide 51 by 903, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 903

Let's proceed to step 3:
903 can be fit into 514 0 times, resulting in a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 514 and we're left with 514.
Bring next digit (0) of the dividend behind the 514 and repeat the process: 5140 / 903

On to step 4:
The number 903 fits into 5140 5 times, leaving a remainder of 625.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4515 away from 5140, we end up with 625.
Take the next digit (3) from the dividend and append it to 625, then repeat: 6253 / 903

Let's proceed to step 5:
903 can be fit into 6253 6 times, resulting in a remainder of 835.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
The remainder is 835 after subtracting 5418 from 6253.
Take the next digit (3) from the dividend and append it to 835, then repeat: 8353 / 903

Step 6:
When dividing 8353 by 903, we get 9 with a remainder of 226.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
If we subtract 8127 from 8353, we get 226.
Grab the next digit (2) from the dividend, add it to 226, then carry on: 2262 / 903

Going ahead to step 7:
When dividing 2262 by 903, we get 2 with a remainder of 456.
Use 2 as the next digit of our solution. 
Result so far: 5692.0
Deduct 1806 from 2262 and we're left with 456.
Bring next digit (2) of the dividend behind the 456 and repeat the process: 4562 / 903

Moving on to step 8:
If we divide 4562 by 903, we get 5 and a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 56925.0
If we subtract 4515 from 4562, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 903, we get 0 and a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 56925.0
Deduct 0 from 470 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 10:
903 goes into 4700 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 56925.05
Subtracting 4515 from 4700 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 11:
If we divide 1850 by 903, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 56925.052
Subtracting 1806 from 1850 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
The number 903 fits into 440 0 times, leaving a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 56925.052
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 13:
If we divide 4400 by 903, we get 4 and a remainder of 788.
Write down 4 as next digit of the result. 
Result so far: 56925.05204
Subtract 3612 from 4400 to get 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Let's proceed to step 14:
The number 903 fits into 7880 8 times, leaving a remainder of 656.
Record the quotient 8 as the next digit in the result. 
Result so far: 56925.052048
Subtracting 7224 from 7880 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Step 15:
903 can be fit into 6560 7 times, resulting in a remainder of 239.
Write down 7 as next digit of the result. 
Result so far: 56925.0520487
If we take 6321 away from 6560, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 16:
903 goes into 2390 2 times with a remainder of 584.
Use 2 as the next digit of our solution. 
Result so far: 56925.05204872
Subtract 1806 from 2390 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

After the division, we end up with 56925.05204872 and a remainder of 5.84e-07.
