We look at the division of 39121565 by 573 
We're looking to find how many times 573 goes into 39121565.

Advancing to step 1:
573 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 573

Let's proceed to step 2:
The number 573 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 573

Step 3:
573 goes into 391 0 times with a remainder of 391.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Append the next digit (2) from the dividend to 391 and continue with: 3912 / 573

Let's proceed to step 4:
The number 573 fits into 3912 6 times, leaving a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 474 after subtracting 3438 from 3912.
Append the next digit (1) from the dividend to 474 and continue with: 4741 / 573

Moving on to step 5:
573 goes into 4741 8 times with a remainder of 157.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 4584 from 4741 and we're left with 157.
Include the next digit (5) from the dividend after 157, then repeat: 1575 / 573

Let's proceed to step 6:
When dividing 1575 by 573, we get 2 with a remainder of 429.
Use 2 as the next digit of our solution. 
Result so far: 682.0
Deduct 1146 from 1575 and we're left with 429.
Bring next digit (6) of the dividend behind the 429 and repeat the process: 4296 / 573

Step 7:
4296 divided by 573 is 7 with a remainder of 285.
Put 7 as the next digit of the answer. 
Result so far: 6827.0
Subtracting 4011 from 4296 leaves us with 285.
Grab the next digit (5) from the dividend, add it to 285, then carry on: 2855 / 573

On to step 8:
573 goes into 2855 4 times with a remainder of 563.
The next digit of our result is 4. 
Result so far: 68274.0
Deduct 2292 from 2855 and we're left with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
If we divide 5630 by 573, we get 9 and a remainder of 473.
The next digit of our result is 9. 
Result so far: 68274.9
Deduct 5157 from 5630 and we're left with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Step 10:
The number 573 fits into 4730 8 times, leaving a remainder of 146.
Use 8 as the next digit of our solution. 
Result so far: 68274.98
If we take 4584 away from 4730, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 11:
1460 divided by 573 is 2 with a remainder of 314.
The next digit of our result is 2. 
Result so far: 68274.982
Subtracting 1146 from 1460 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 12:
3140 divided by 573 is 5 with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 68274.9825
Subtract 2865 from 3140 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 13:
When dividing 2750 by 573, we get 4 with a remainder of 458.
The number 4 becomes the next digit in our result. 
Result so far: 68274.98254
Subtract 2292 from 2750 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

On to step 14:
When dividing 4580 by 573, we get 7 with a remainder of 569.
Use 7 as the next digit of our solution. 
Result so far: 68274.982547
Subtracting 4011 from 4580 leaves us 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.

Let's proceed to step 15:
573 goes into 5690 9 times with a remainder of 533.
The next digit of our result is 9. 
Result so far: 68274.9825479
If we subtract 5157 from 5690, we get 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 16:
5330 divided by 573 is 9 with a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 68274.98254799
If we subtract 5157 from 5330, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 68274.98254799 with a remainder of 1.73e-07.
