45165873 ÷ 596 
Let's see how many times 596 fits into 45165873.

On to step 1:
When dividing 4 by 596, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 596

Moving on to step 2:
When dividing 45 by 596, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 596

Let's proceed to step 3:
The number 596 fits into 451 0 times, leaving a remainder of 451.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 451 and we're left with 451.
Take the next digit (6) from the dividend and append it to 451, then repeat: 4516 / 596

Going ahead to step 4:
The number 596 fits into 4516 7 times, leaving a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4172 from 4516, we get 344.
Bring next digit (5) of the dividend behind the 344 and repeat the process: 3445 / 596

On to step 5:
If we divide 3445 by 596, we get 5 and a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 2980 from 3445, we get 465.
Take the next digit (8) from the dividend and append it to 465, then repeat: 4658 / 596

Step 6:
596 goes into 4658 7 times with a remainder of 486.
The next digit of our result is 7. 
Result so far: 757.0
If we take 4172 away from 4658, we end up with 486.
Fetch the next digit (7) from the dividend, attach it to 486 and continue: 4867 / 596

Let's proceed to step 7:
If we divide 4867 by 596, we get 8 and a remainder of 99.
Write down 8 as next digit of the result. 
Result so far: 7578.0
If we subtract 4768 from 4867, we get 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 596

Moving on to step 8:
596 can be fit into 993 1 times, resulting in a remainder of 397.
The number 1 becomes the next digit in our result. 
Result so far: 75781.0
If we take 596 away from 993, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 9:
596 can be fit into 3970 6 times, resulting in a remainder of 394.
Record the quotient 6 as the next digit in the result. 
Result so far: 75781.6
Subtracting 3576 from 3970 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 10:
596 goes into 3940 6 times with a remainder of 364.
Use 6 as the next digit of our solution. 
Result so far: 75781.66
The remainder is 364 after subtracting 3576 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 75781.66 with a remainder of 0.364.
