903813 ÷ 75 
Our goal is to divide 903813 by 75.

Going ahead to step 1:
The number 75 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 75

Going ahead to step 2:
When dividing 90 by 75, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 75 from 90 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 75

Step 3:
When dividing 153 by 75, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 150 away from 153, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 75

Moving on to step 4:
75 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtracting 0 from 38 leaves us with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 75

On to step 5:
If we divide 381 by 75, we get 5 and a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1205.0
If we take 375 away from 381, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 75

On to step 6:
The number 75 fits into 63 0 times, leaving a remainder of 63.
The next digit of our result is 0. 
Result so far: 12050.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
75 can be fit into 630 8 times, resulting in a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 12050.8
If we take 600 away from 630, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
75 goes into 300 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 12050.84
Subtract 300 from 300 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12050.84
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12050.84
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12050.84 and a remainder of 0.0.
