90336403 ÷ 506 
Let's see how many times 506 fits into 90336403.

Moving on to step 1:
506 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 506

On to step 2:
506 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 506

On to step 3:
If we divide 903 by 506, we get 1 and a remainder of 397.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 506 away from 903, we end up with 397.
Append the next digit (3) from the dividend to 397 and continue with: 3973 / 506

Step 4:
506 goes into 3973 7 times with a remainder of 431.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 3542 from 3973 leaves us with 431.
Fetch the next digit (6) from the dividend, attach it to 431 and continue: 4316 / 506

Moving on to step 5:
506 can be fit into 4316 8 times, resulting in a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 178.0
If we take 4048 away from 4316, we end up with 268.
Append the next digit (4) from the dividend to 268 and continue with: 2684 / 506

Moving on to step 6:
506 can be fit into 2684 5 times, resulting in a remainder of 154.
Write down 5 as next digit of the result. 
Result so far: 1785.0
The remainder is 154 after subtracting 2530 from 2684.
Fetch the next digit (0) from the dividend, attach it to 154 and continue: 1540 / 506

On to step 7:
506 can be fit into 1540 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 17853.0
Deduct 1518 from 1540 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 506

Moving on to step 8:
506 goes into 223 0 times with a remainder of 223.
The next digit of our result is 0. 
Result so far: 178530.0
If we take 0 away from 223, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 9:
506 goes into 2230 4 times with a remainder of 206.
Use 4 as the next digit of our solution. 
Result so far: 178530.4
If we take 2024 away from 2230, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 10:
If we divide 2060 by 506, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 178530.44
Deduct 2024 from 2060 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 178530.44, with a leftover of 0.036.
