Let's divide 725387 by 45
We want to figure out the number of times 725387 can be divided by 45.

Going ahead to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Going ahead to step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 72, we get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 45

Moving on to step 3:
275 divided by 45 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 5 after subtracting 270 from 275.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 45

Moving on to step 4:
If we divide 53 by 45, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we subtract 45 from 53, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 45

Step 5:
If we divide 88 by 45, we get 1 and a remainder of 43.
The next digit of our result is 1. 
Result so far: 1611.0
Deduct 45 from 88 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 45

On to step 6:
If we divide 437 by 45, we get 9 and a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 16119.0
Deduct 405 from 437 and we're left 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.

Going ahead to step 7:
45 can be fit into 320 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 16119.7
The remainder is 5 after subtracting 315 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 16119.71
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 16119.711
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 16119.711 with a remainder of 0.0005.
