45725584 ÷ 525 
Our goal is to divide 45725584 by 525.

Step 1:
The number 525 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 525

On to step 2:
The number 525 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 525

On to step 3:
When dividing 457 by 525, we get 0 with a remainder of 457.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 457 leaves us with 457.
Take the next digit (2) from the dividend and append it to 457, then repeat: 4572 / 525

Let's proceed to step 4:
525 can be fit into 4572 8 times, resulting in a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 4200 from 4572, we get 372.
Grab the next digit (5) from the dividend, add it to 372, then carry on: 3725 / 525

Going ahead to step 5:
525 goes into 3725 7 times with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 3675 from 3725 and we're left with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 525

Moving on to step 6:
525 goes into 505 0 times with a remainder of 505.
Write down 0 as next digit of the result. 
Result so far: 870.0
Subtract 0 from 505 to get 505.
Fetch the next digit (8) from the dividend, attach it to 505 and continue: 5058 / 525

Advancing to step 7:
5058 divided by 525 is 9 with a remainder of 333.
Use 9 as the next digit of our solution. 
Result so far: 8709.0
Subtract 4725 from 5058 to get 333.
Take the next digit (4) from the dividend and append it to 333, then repeat: 3334 / 525

Advancing to step 8:
525 can be fit into 3334 6 times, resulting in a remainder of 184.
The next digit of our result is 6. 
Result so far: 87096.0
If we subtract 3150 from 3334, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 9:
1840 divided by 525 is 3 with a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 87096.3
Subtracting 1575 from 1840 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
The number 525 fits into 2650 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 87096.35
Subtract 2625 from 2650 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 525, we get 0 and a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 87096.35
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 12:
The number 525 fits into 2500 4 times, leaving a remainder of 400.
Use 4 as the next digit of our solution. 
Result so far: 87096.3504
Subtract 2100 from 2500 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
When dividing 4000 by 525, we get 7 with a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 87096.35047
The remainder is 325 after subtracting 3675 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 14:
The number 525 fits into 3250 6 times, leaving a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 87096.350476
If we subtract 3150 from 3250, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
525 can be fit into 1000 1 times, resulting in a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 87096.3504761
Deduct 525 from 1000 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 16:
When dividing 4750 by 525, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 87096.35047619
Subtract 4725 from 4750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 87096.35047619 and a remainder of 2.5e-08.
