We look at the division of 35931124 by 903 
We want to divide 35931124 by 903.

Advancing to step 1:
3 divided by 903 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 903

Advancing to step 2:
903 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 903

Advancing to step 3:
903 can be fit into 359 0 times, resulting in a remainder of 359.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 359, we end up with 359.
Fetch the next digit (3) from the dividend, attach it to 359 and continue: 3593 / 903

On to step 4:
903 can be fit into 3593 3 times, resulting in a remainder of 884.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2709 from 3593 and we're left with 884.
Bring next digit (1) of the dividend behind the 884 and repeat the process: 8841 / 903

Step 5:
8841 divided by 903 is 9 with a remainder of 714.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 8127 away from 8841, we end up with 714.
Include the next digit (1) from the dividend after 714, then repeat: 7141 / 903

On to step 6:
7141 divided by 903 is 7 with a remainder of 820.
Write down 7 as next digit of the result. 
Result so far: 397.0
If we take 6321 away from 7141, we end up with 820.
Take the next digit (2) from the dividend and append it to 820, then repeat: 8202 / 903

Advancing to step 7:
903 goes into 8202 9 times with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 3979.0
Subtracting 8127 from 8202 leaves us with 75.
Take the next digit (4) from the dividend and append it to 75, then repeat: 754 / 903

Let's proceed to step 8:
If we divide 754 by 903, we get 0 and a remainder of 754.
Record the quotient 0 as the next digit in the result. 
Result so far: 39790.0
The remainder is 754 after subtracting 0 from 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Let's proceed to step 9:
When dividing 7540 by 903, we get 8 with a remainder of 316.
Record the quotient 8 as the next digit in the result. 
Result so far: 39790.8
If we subtract 7224 from 7540, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 10:
903 goes into 3160 3 times with a remainder of 451.
The next digit of our result is 3. 
Result so far: 39790.83
If we take 2709 away from 3160, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 11:
If we divide 4510 by 903, we get 4 and a remainder of 898.
The number 4 becomes the next digit in our result. 
Result so far: 39790.834
The remainder is 898 after subtracting 3612 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8980, and continue the process.

On to step 12:
903 goes into 8980 9 times with a remainder of 853.
Record the quotient 9 as the next digit in the result. 
Result so far: 39790.8349
If we take 8127 away from 8980, we end up with 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Going ahead to step 13:
The number 903 fits into 8530 9 times, leaving a remainder of 403.
Put 9 as the next digit of the answer. 
Result so far: 39790.83499
Subtracting 8127 from 8530 leaves us with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

The final result is 39790.83499 with a remainder of 0.000403.
