45015251 ÷ 480 
We're looking to find how many times 480 goes into 45015251.

Advancing to step 1:
When dividing 4 by 480, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 480

Advancing to step 2:
480 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 480

Let's proceed to step 3:
When dividing 450 by 480, we get 0 with a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 450, we get 450.
Take the next digit (1) from the dividend and append it to 450, then repeat: 4501 / 480

Step 4:
The number 480 fits into 4501 9 times, leaving a remainder of 181.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 4320 away from 4501, we end up with 181.
Bring next digit (5) of the dividend behind the 181 and repeat the process: 1815 / 480

Step 5:
The number 480 fits into 1815 3 times, leaving a remainder of 375.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtract 1440 from 1815 to get 375.
Grab the next digit (2) from the dividend, add it to 375, then carry on: 3752 / 480

Advancing to step 6:
If we divide 3752 by 480, we get 7 and a remainder of 392.
The number 7 becomes the next digit in our result. 
Result so far: 937.0
If we subtract 3360 from 3752, we get 392.
Grab the next digit (5) from the dividend, add it to 392, then carry on: 3925 / 480

Moving on to step 7:
If we divide 3925 by 480, we get 8 and a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 9378.0
Subtract 3840 from 3925 to get 85.
Take the next digit (1) from the dividend and append it to 85, then repeat: 851 / 480

Advancing to step 8:
851 divided by 480 is 1 with a remainder of 371.
Use 1 as the next digit of our solution. 
Result so far: 93781.0
If we subtract 480 from 851, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 9:
480 goes into 3710 7 times with a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 93781.7
If we take 3360 away from 3710, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 10:
3500 divided by 480 is 7 with a remainder of 140.
The number 7 becomes the next digit in our result. 
Result so far: 93781.77
Subtracting 3360 from 3500 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 93781.77 with a remaining 0.14.
