We're dividing 742963 by 45 
Let's see how many times 45 fits into 742963.

Step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 45

Let's proceed to step 2:
45 can be fit into 74 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 29 after subtracting 45 from 74.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 45

Step 3:
45 goes into 292 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 270 from 292 and we're left with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 45

On to step 4:
When dividing 229 by 45, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 225 from 229, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 45

Let's proceed to step 5:
45 can be fit into 46 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1651.0
Subtract 45 from 46 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 45

Moving on to step 6:
13 divided by 45 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 16510.0
Deduct 0 from 13 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
45 goes into 130 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 16510.2
Deduct 90 from 130 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
400 divided by 45 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 16510.28
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 16510.288
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 16510.288, with a leftover of 0.004.
