We're dividing 35405165 by 903 
Our goal is to divide 35405165 by 903.

Moving on to step 1:
903 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 903

Moving on to step 2:
35 divided by 903 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 903

On to step 3:
354 divided by 903 is 0 with a remainder of 354.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 354, we get 354.
Take the next digit (0) from the dividend and append it to 354, then repeat: 3540 / 903

Advancing to step 4:
903 goes into 3540 3 times with a remainder of 831.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2709 from 3540, we get 831.
Include the next digit (5) from the dividend after 831, then repeat: 8315 / 903

Going ahead to step 5:
8315 divided by 903 is 9 with a remainder of 188.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 8127 away from 8315, we end up with 188.
Include the next digit (1) from the dividend after 188, then repeat: 1881 / 903

Step 6:
1881 divided by 903 is 2 with a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 392.0
Subtracting 1806 from 1881 leaves us with 75.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 903

Going ahead to step 7:
903 can be fit into 756 0 times, resulting in a remainder of 756.
Use 0 as the next digit of our solution. 
Result so far: 3920.0
Subtracting 0 from 756 leaves us with 756.
Fetch the next digit (5) from the dividend, attach it to 756 and continue: 7565 / 903

Moving on to step 8:
903 can be fit into 7565 8 times, resulting in a remainder of 341.
Record the quotient 8 as the next digit in the result. 
Result so far: 39208.0
Subtract 7224 from 7565 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Step 9:
3410 divided by 903 is 3 with a remainder of 701.
Use 3 as the next digit of our solution. 
Result so far: 39208.3
Subtracting 2709 from 3410 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 10:
903 can be fit into 7010 7 times, resulting in a remainder of 689.
Use 7 as the next digit of our solution. 
Result so far: 39208.37
If we subtract 6321 from 7010, we get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 11:
903 goes into 6890 7 times with a remainder of 569.
The number 7 becomes the next digit in our result. 
Result so far: 39208.377
If we take 6321 away from 6890, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

The quotient of the division is 39208.377, and the remainder is 0.0569.
