748061 ÷ 45 
We're looking to find how many times 45 goes into 748061.

Moving on to step 1:
When dividing 7 by 45, we get 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.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 45

Advancing to step 2:
The number 45 fits into 74 1 times, leaving 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.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 45

Let's proceed to step 3:
45 goes into 298 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 270 from 298 and we're left with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 45

Let's proceed to step 4:
45 goes into 280 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 270 from 280, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 45

Going ahead to step 5:
The number 45 fits into 106 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1662.0
Deduct 90 from 106 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 45

On to step 6:
45 can be fit into 161 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 16623.0
The remainder is 26 after subtracting 135 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 45, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 16623.5
Deduct 225 from 260 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
The next digit of our result is 7. 
Result so far: 16623.57
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 45 is 7 with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 16623.577
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 16623.577, with a leftover of 0.0035.
