757658 ÷ 45 
We're looking to find how many times 45 goes into 757658.

On to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 45

Let's proceed to step 2:
The number 45 fits into 75 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 30 after subtracting 45 from 75.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 45

Step 3:
The number 45 fits into 307 6 times, leaving a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 37 after subtracting 270 from 307.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 45

Going ahead to step 4:
If we divide 376 by 45, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 168.0
Subtract 360 from 376 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 45

Advancing to step 5:
When dividing 165 by 45, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 1683.0
Deduct 135 from 165 and we're left with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 45

On to step 6:
If we divide 308 by 45, we get 6 and a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 16836.0
Subtract 270 from 308 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 45, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 16836.8
Subtracting 360 from 380 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 16836.84
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 45 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 16836.844
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 16836.844 and a remainder of 0.002.
