39258781 ÷ 673 
Our goal is to divide 39258781 by 673.

Advancing to step 1:
When dividing 3 by 673, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 673

On to step 2:
673 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 673

On to step 3:
If we divide 392 by 673, we get 0 and a remainder of 392.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 392 leaves us with 392.
Include the next digit (5) from the dividend after 392, then repeat: 3925 / 673

Moving on to step 4:
3925 divided by 673 is 5 with a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3365 from 3925, we get 560.
Take the next digit (8) from the dividend and append it to 560, then repeat: 5608 / 673

Step 5:
5608 divided by 673 is 8 with a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Deduct 5384 from 5608 and we're left with 224.
Fetch the next digit (7) from the dividend, attach it to 224 and continue: 2247 / 673

Going ahead to step 6:
673 can be fit into 2247 3 times, resulting in a remainder of 228.
Use 3 as the next digit of our solution. 
Result so far: 583.0
Deduct 2019 from 2247 and we're left with 228.
Bring next digit (8) of the dividend behind the 228 and repeat the process: 2288 / 673

Let's proceed to step 7:
The number 673 fits into 2288 3 times, leaving a remainder of 269.
The number 3 becomes the next digit in our result. 
Result so far: 5833.0
Subtract 2019 from 2288 to get 269.
Append the next digit (1) from the dividend to 269 and continue with: 2691 / 673

Let's proceed to step 8:
673 can be fit into 2691 3 times, resulting in a remainder of 672.
The number 3 becomes the next digit in our result. 
Result so far: 58333.0
Subtracting 2019 from 2691 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 9:
When dividing 6720 by 673, we get 9 with a remainder of 663.
The number 9 becomes the next digit in our result. 
Result so far: 58333.9
If we take 6057 away from 6720, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 10:
If we divide 6630 by 673, we get 9 and a remainder of 573.
Put 9 as the next digit of the answer. 
Result so far: 58333.99
The remainder is 573 after subtracting 6057 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

The final result is 58333.99 with a remainder of 0.573.
