725379 divided by 45 
We want to divide 725379 by 45.

Step 1:
45 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Let's proceed to step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 72 and we're left with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 45

Let's proceed to step 3:
275 divided by 45 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 270 from 275 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 45

Step 4:
53 divided by 45 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 161.0
The remainder is 8 after subtracting 45 from 53.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 45

Step 5:
45 can be fit into 87 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 1611.0
Deduct 45 from 87 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 45

On to step 6:
When dividing 429 by 45, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 16119.0
If we take 405 away from 429, 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.

Moving on to step 7:
The number 45 fits into 240 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 16119.5
Deduct 225 from 240 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 16119.53
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 16119.533
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 16119.533, and the remainder is 0.0015.
