Let's proceed to step 5:
The number 803 fits into 7283 9 times, leaving a remainder of 56.
The next digit of our result is 9. 
Result so far: 39.0
If we take 7227 away from 7283, we end up with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 803

Advancing to step 6:
803 goes into 560 0 times with a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Deduct 0 from 560 and we're left with 560.
Take the next digit (8) from the dividend and append it to 560, then repeat: 5608 / 803

Step 7:
5608 divided by 803 is 6 with a remainder of 790.
Use 6 as the next digit of our solution. 
Result so far: 3906.0
If we subtract 4818 from 5608, we get 790.
Fetch the next digit (9) from the dividend, attach it to 790 and continue: 7909 / 803

Going ahead to step 8:
If we divide 7909 by 803, we get 9 and a remainder of 682.
The next digit of our result is 9. 
Result so far: 39069.0
The remainder is 682 after subtracting 7227 from 7909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 9:
6820 divided by 803 is 8 with a remainder of 396.
Write down 8 as next digit of the result. 
Result so far: 39069.8
If we take 6424 away from 6820, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 10:
If we divide 3960 by 803, we get 4 and a remainder of 748.
Put 4 as the next digit of the answer. 
Result so far: 39069.84
If we subtract 3212 from 3960, we get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Moving on to step 11:
The number 803 fits into 7480 9 times, leaving a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 39069.849
The remainder is 253 after subtracting 7227 from 7480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 12:
803 goes into 2530 3 times with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 39069.8493
Subtract 2409 from 2530 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 13:
1210 divided by 803 is 1 with a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 39069.84931
Deduct 803 from 1210 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 14:
When dividing 4070 by 803, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 39069.849315
If we take 4015 away from 4070, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 15:
The number 803 fits into 550 0 times, leaving a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 39069.849315
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Let's proceed to step 16:
803 goes into 5500 6 times with a remainder of 682.
Write down 6 as next digit of the result. 
Result so far: 39069.84931506
Subtract 4818 from 5500 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Our division results in 39069.84931506 with a remaining 6.82e-07.
