Step 4:
5533 divided by 903 is 6 with a remainder of 115.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5418 away from 5533, we end up with 115.
Append the next digit (8) from the dividend to 115 and continue with: 1158 / 903

Moving on to step 5:
903 goes into 1158 1 times with a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
The remainder is 255 after subtracting 903 from 1158.
Bring next digit (7) of the dividend behind the 255 and repeat the process: 2557 / 903

Going ahead to step 6:
The number 903 fits into 2557 2 times, leaving a remainder of 751.
Use 2 as the next digit of our solution. 
Result so far: 612.0
If we subtract 1806 from 2557, we get 751.
Fetch the next digit (7) from the dividend, attach it to 751 and continue: 7517 / 903

Moving on to step 7:
If we divide 7517 by 903, we get 8 and a remainder of 293.
The next digit of our result is 8. 
Result so far: 6128.0
Deduct 7224 from 7517 and we're left with 293.
Include the next digit (5) from the dividend after 293, then repeat: 2935 / 903

Step 8:
When dividing 2935 by 903, we get 3 with a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 61283.0
Deduct 2709 from 2935 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
If we divide 2260 by 903, we get 2 and a remainder of 454.
The next digit of our result is 2. 
Result so far: 61283.2
If we subtract 1806 from 2260, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 10:
903 goes into 4540 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 61283.25
Subtracting 4515 from 4540 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
250 divided by 903 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 61283.25
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
903 goes into 2500 2 times with a remainder of 694.
The next digit of our result is 2. 
Result so far: 61283.2502
The remainder is 694 after subtracting 1806 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 13:
If we divide 6940 by 903, we get 7 and a remainder of 619.
Write down 7 as next digit of the result. 
Result so far: 61283.25027
If we subtract 6321 from 6940, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Step 14:
If we divide 6190 by 903, we get 6 and a remainder of 772.
The number 6 becomes the next digit in our result. 
Result so far: 61283.250276
Deduct 5418 from 6190 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

On to step 15:
The number 903 fits into 7720 8 times, leaving a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 61283.2502768
The remainder is 496 after subtracting 7224 from 7720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 16:
903 can be fit into 4960 5 times, resulting in a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 61283.25027685
Subtract 4515 from 4960 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final outcome is 61283.25027685, with a leftover of 4.45e-07.
