On to step 1:
803 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 803

Step 2:
43 divided by 803 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 803

On to step 3:
803 goes into 438 0 times with a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 438, we get 438.
Grab the next digit (6) from the dividend, add it to 438, then carry on: 4386 / 803

When dividing 4386 by 803, we get 5 with a remainder of 371.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 4015 from 4386 leaves us with 371.
Include the next digit (8) from the dividend after 371, then repeat: 3718 / 803

Moving on to step 5:
803 can be fit into 3718 4 times, resulting in a remainder of 506.
Write down 4 as next digit of the result. 
Result so far: 54.0
Subtract 3212 from 3718 to get 506.
Grab the next digit (5) from the dividend, add it to 506, then carry on: 5065 / 803

Moving on to step 6:
The number 803 fits into 5065 6 times, leaving a remainder of 247.
The next digit of our result is 6. 
Result so far: 546.0
If we take 4818 away from 5065, we end up with 247.
Fetch the next digit (0) from the dividend, attach it to 247 and continue: 2470 / 803

Moving on to step 7:
2470 divided by 803 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 5463.0
If we take 2409 away from 2470, we end up with 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 803

Moving on to step 8:
The number 803 fits into 619 0 times, leaving a remainder of 619.
Record the quotient 0 as the next digit in the result. 
Result so far: 54630.0
Subtract 0 from 619 to 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.

Advancing to step 9:
6190 divided by 803 is 7 with a remainder of 569.
Put 7 as the next digit of the answer. 
Result so far: 54630.7
Deduct 5621 from 6190 and we're left 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.

Step 10:
If we divide 5690 by 803, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 54630.77
The remainder is 69 after subtracting 5621 from 5690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The final outcome is 54630.77, with a leftover of 0.069.
