Let's divide 399933 by 45
Let's see how many times 45 fits into 399933.

Going ahead to step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 45

Advancing to step 2:
45 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 45

On to step 3:
The number 45 fits into 399 8 times, leaving a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 360 away from 399, we end up with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 45

Going ahead to step 4:
399 divided by 45 is 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 39 after subtracting 360 from 399.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 45

Moving on to step 5:
If we divide 393 by 45, we get 8 and a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 888.0
If we take 360 away from 393, we end up with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 45

Going ahead to step 6:
When dividing 333 by 45, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 8887.0
Subtract 315 from 333 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 45, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 8887.4
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 45, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8887.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8887.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 8887.4, with a leftover of 0.0.
