38990818 ÷ 903 
Let's see how many times 903 fits into 38990818.

On to step 1:
903 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 903

Advancing to step 2:
903 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 903

On to step 3:
903 can be fit into 389 0 times, resulting in a remainder of 389.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 389 and we're left with 389.
Append the next digit (9) from the dividend to 389 and continue with: 3899 / 903

Advancing to step 4:
The number 903 fits into 3899 4 times, leaving a remainder of 287.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3612 from 3899, we get 287.
Append the next digit (0) from the dividend to 287 and continue with: 2870 / 903

On to step 5:
2870 divided by 903 is 3 with a remainder of 161.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 2709 from 2870 leaves us with 161.
Bring next digit (8) of the dividend behind the 161 and repeat the process: 1618 / 903

Let's proceed to step 6:
If we divide 1618 by 903, we get 1 and a remainder of 715.
Write down 1 as next digit of the result. 
Result so far: 431.0
If we take 903 away from 1618, we end up with 715.
Take the next digit (1) from the dividend and append it to 715, then repeat: 7151 / 903

Let's proceed to step 7:
903 goes into 7151 7 times with a remainder of 830.
Put 7 as the next digit of the answer. 
Result so far: 4317.0
Subtracting 6321 from 7151 leaves us with 830.
Include the next digit (8) from the dividend after 830, then repeat: 8308 / 903

Going ahead to step 8:
If we divide 8308 by 903, we get 9 and a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 43179.0
If we take 8127 away from 8308, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 9:
1810 divided by 903 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 43179.2
If we subtract 1806 from 1810, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
903 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 43179.2
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
903 goes into 400 0 times with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 43179.2
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The quotient of the division is 43179.2, and the remainder is 0.04.
