64453308 ÷ 725 
Let's see how many times 725 fits into 64453308.

Moving on to step 1:
725 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 725

Advancing to step 2:
When dividing 64 by 725, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 725

Advancing to step 3:
If we divide 644 by 725, we get 0 and a remainder of 644.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 644 to get 644.
Grab the next digit (5) from the dividend, add it to 644, then carry on: 6445 / 725

Moving on to step 4:
The number 725 fits into 6445 8 times, leaving a remainder of 645.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5800 from 6445 to get 645.
Grab the next digit (3) from the dividend, add it to 645, then carry on: 6453 / 725

Advancing to step 5:
6453 divided by 725 is 8 with a remainder of 653.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 653 after subtracting 5800 from 6453.
Include the next digit (3) from the dividend after 653, then repeat: 6533 / 725

Let's proceed to step 6:
6533 divided by 725 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 889.0
Subtracting 6525 from 6533 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 725

Moving on to step 7:
80 divided by 725 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 8890.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 725

On to step 8:
725 goes into 808 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 88901.0
If we subtract 725 from 808, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
The number 725 fits into 830 1 times, leaving a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 88901.1
Subtract 725 from 830 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 10:
725 goes into 1050 1 times with a remainder of 325.
Write down 1 as next digit of the result. 
Result so far: 88901.11
Subtracting 725 from 1050 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 88901.11 and a remainder of 0.325.
