746410 ÷ 45 
We want to figure out the number of times 746410 can be divided by 45.

Advancing to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 45

Going ahead to step 2:
45 can be fit into 74 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 74, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 45

Step 3:
45 goes into 296 6 times with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 270 away from 296, we end up with 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 45

On to step 4:
45 can be fit into 264 5 times, resulting in a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtract 225 from 264 to get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 45

Advancing to step 5:
When dividing 391 by 45, we get 8 with a remainder of 31.
The next digit of our result is 8. 
Result so far: 1658.0
The remainder is 31 after subtracting 360 from 391.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 45

Advancing to step 6:
If we divide 310 by 45, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 16586.0
If we take 270 away from 310, 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.

Let's proceed to step 7:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 16586.8
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.

Let's proceed to step 8:
45 goes into 400 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 16586.88
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.

The final outcome is 16586.88, with a leftover of 0.04.
