746812 ÷ 45 
We're looking to find how many times 45 goes into 746812.

Let's proceed to step 1:
7 divided by 45 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 45

On to step 2:
74 divided by 45 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 74, we get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 45

Step 3:
The number 45 fits into 296 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 26 after subtracting 270 from 296.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 45

Step 4:
When dividing 268 by 45, we get 5 with a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 225 from 268 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 45

On to step 5:
431 divided by 45 is 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 1659.0
Deduct 405 from 431 and we're left with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 45

Advancing to step 6:
45 goes into 262 5 times with a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 16595.0
If we subtract 225 from 262, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
45 goes into 370 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 16595.8
Deduct 360 from 370 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 16595.82
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 16595.822
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 16595.822 with a remainder of 0.001.
