51591780 ÷ 573 
We're looking to find how many times 573 goes into 51591780.

On to step 1:
When dividing 5 by 573, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 573

Moving on to step 2:
573 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 573

Let's proceed to step 3:
573 goes into 515 0 times with a remainder of 515.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Fetch the next digit (9) from the dividend, attach it to 515 and continue: 5159 / 573

Moving on to step 4:
When dividing 5159 by 573, we get 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 5157 from 5159 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 573

Let's proceed to step 5:
21 divided by 573 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 573

Going ahead to step 6:
If we divide 217 by 573, we get 0 and a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 900.0
Deduct 0 from 217 and we're left with 217.
Take the next digit (8) from the dividend and append it to 217, then repeat: 2178 / 573

On to step 7:
573 can be fit into 2178 3 times, resulting in a remainder of 459.
Use 3 as the next digit of our solution. 
Result so far: 9003.0
Subtract 1719 from 2178 to get 459.
Append the next digit (0) from the dividend to 459 and continue with: 4590 / 573

On to step 8:
The number 573 fits into 4590 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 90038.0
The remainder is 6 after subtracting 4584 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
573 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 90038.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
The number 573 fits into 600 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 90038.01
If we subtract 573 from 600, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 11:
573 goes into 270 0 times with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 90038.01
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 12:
When dividing 2700 by 573, we get 4 with a remainder of 408.
Put 4 as the next digit of the answer. 
Result so far: 90038.0104
If we take 2292 away from 2700, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 13:
573 can be fit into 4080 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 90038.01047
If we subtract 4011 from 4080, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
When dividing 690 by 573, we get 1 with a remainder of 117.
Write down 1 as next digit of the result. 
Result so far: 90038.010471
If we take 573 away from 690, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Going ahead to step 15:
When dividing 1170 by 573, we get 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 90038.0104712
If we take 1146 away from 1170, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 16:
If we divide 240 by 573, we get 0 and a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 90038.0104712
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 90038.0104712 with a balance of 2.4e-07.
