407409 divided by 45 
We want to divide 407409 by 45.

Let's proceed to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 45

Going ahead to step 2:
If we divide 40 by 45, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (7) from the dividend, add it to 40, then carry on: 407 / 45

Let's proceed to step 3:
45 goes into 407 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 2 after subtracting 405 from 407.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 45

Let's proceed to step 4:
45 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 24 after subtracting 0 from 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 45

Moving on to step 5:
The number 45 fits into 240 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 905.0
If we take 225 away from 240, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 45

Step 6:
159 divided by 45 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 9053.0
Deduct 135 from 159 and we're left 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.

On to step 7:
45 goes into 240 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 9053.5
Subtract 225 from 240 to 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.

Moving on to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 9053.53
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.

Moving on to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 9053.533
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.

The final outcome is 9053.533, with a leftover of 0.0015.
