We're dividing 30571438 by 903 
We want to divide 30571438 by 903.

Step 1:
903 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 903

Let's proceed to step 2:
If we divide 30 by 903, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 903

On to step 3:
305 divided by 903 is 0 with a remainder of 305.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 305 to get 305.
Take the next digit (7) from the dividend and append it to 305, then repeat: 3057 / 903

Let's proceed to step 4:
If we divide 3057 by 903, we get 3 and a remainder of 348.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2709 from 3057 leaves us with 348.
Append the next digit (1) from the dividend to 348 and continue with: 3481 / 903

Let's proceed to step 5:
3481 divided by 903 is 3 with a remainder of 772.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 2709 from 3481, we get 772.
Bring next digit (4) of the dividend behind the 772 and repeat the process: 7724 / 903

Advancing to step 6:
When dividing 7724 by 903, we get 8 with a remainder of 500.
The next digit of our result is 8. 
Result so far: 338.0
If we subtract 7224 from 7724, we get 500.
Bring next digit (3) of the dividend behind the 500 and repeat the process: 5003 / 903

On to step 7:
903 goes into 5003 5 times with a remainder of 488.
The number 5 becomes the next digit in our result. 
Result so far: 3385.0
If we subtract 4515 from 5003, we get 488.
Bring next digit (8) of the dividend behind the 488 and repeat the process: 4888 / 903

Step 8:
When dividing 4888 by 903, we get 5 with a remainder of 373.
Record the quotient 5 as the next digit in the result. 
Result so far: 33855.0
Subtracting 4515 from 4888 leaves us with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
903 goes into 3730 4 times with a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 33855.4
The remainder is 118 after subtracting 3612 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
When dividing 1180 by 903, we get 1 with a remainder of 277.
The number 1 becomes the next digit in our result. 
Result so far: 33855.41
The remainder is 277 after subtracting 903 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 11:
When dividing 2770 by 903, we get 3 with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 33855.413
If we take 2709 away from 2770, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
903 can be fit into 610 0 times, resulting in a remainder of 610.
Write down 0 as next digit of the result. 
Result so far: 33855.413
If we take 0 away from 610, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 13:
When dividing 6100 by 903, we get 6 with a remainder of 682.
Write down 6 as next digit of the result. 
Result so far: 33855.41306
Subtract 5418 from 6100 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 14:
When dividing 6820 by 903, we get 7 with a remainder of 499.
Record the quotient 7 as the next digit in the result. 
Result so far: 33855.413067
Deduct 6321 from 6820 and we're left with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 15:
4990 divided by 903 is 5 with a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 33855.4130675
If we subtract 4515 from 4990, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 16:
The number 903 fits into 4750 5 times, leaving a remainder of 235.
Use 5 as the next digit of our solution. 
Result so far: 33855.41306755
Deduct 4515 from 4750 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Our division results in 33855.41306755 with a remaining 2.35e-07.
