40455320 ÷ 576 
We want to divide 40455320 by 576.

Going ahead to step 1:
When dividing 4 by 576, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 576

Let's proceed to step 2:
If we divide 40 by 576, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 576

Step 3:
576 goes into 404 0 times with a remainder of 404.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 404 leaves us with 404.
Bring next digit (5) of the dividend behind the 404 and repeat the process: 4045 / 576

Step 4:
The number 576 fits into 4045 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 4032 away from 4045, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 576

Step 5:
576 goes into 135 0 times with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 135 after subtracting 0 from 135.
Take the next digit (3) from the dividend and append it to 135, then repeat: 1353 / 576

Going ahead to step 6:
When dividing 1353 by 576, we get 2 with a remainder of 201.
The next digit of our result is 2. 
Result so far: 702.0
Subtracting 1152 from 1353 leaves us with 201.
Take the next digit (2) from the dividend and append it to 201, then repeat: 2012 / 576

Moving on to step 7:
576 can be fit into 2012 3 times, resulting in a remainder of 284.
The next digit of our result is 3. 
Result so far: 7023.0
Deduct 1728 from 2012 and we're left with 284.
Include the next digit (0) from the dividend after 284, then repeat: 2840 / 576

Moving on to step 8:
576 goes into 2840 4 times with a remainder of 536.
Record the quotient 4 as the next digit in the result. 
Result so far: 70234.0
Subtract 2304 from 2840 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 9:
576 can be fit into 5360 9 times, resulting in a remainder of 176.
Use 9 as the next digit of our solution. 
Result so far: 70234.9
If we take 5184 away from 5360, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
The number 576 fits into 1760 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 70234.93
If we take 1728 away from 1760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 576 fits into 320 0 times, leaving a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 70234.93
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 576, we get 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 70234.9305
The remainder is 320 after subtracting 2880 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
If we divide 3200 by 576, we get 5 and a remainder of 320.
The number 5 becomes the next digit in our result. 
Result so far: 70234.93055
Subtract 2880 from 3200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final result is 70234.93055 with a remainder of 0.00032.
