We divide 407396 by 45
We want to figure out the number of times 407396 can be divided by 45.

Let's proceed to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 45

Going ahead to step 2:
When dividing 40 by 45, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 45

Let's proceed to step 3:
If we divide 407 by 45, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 405 away from 407, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 45

On to step 4:
When dividing 23 by 45, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

On to step 5:
45 can be fit into 239 5 times, resulting in a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 905.0
Deduct 225 from 239 and we're left with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 45

Let's proceed to step 6:
The number 45 fits into 146 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9053.0
Subtract 135 from 146 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
45 can be fit into 110 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 9053.2
Subtracting 90 from 110 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 9053.24
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 9053.244
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 9053.244 and a remainder of 0.002.
