We divide 87097609 by 480
We want to figure out the number of times 87097609 can be divided by 480.

On to step 1:
The number 480 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 480

On to step 2:
87 divided by 480 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 480

On to step 3:
When dividing 870 by 480, we get 1 with a remainder of 390.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 480 from 870 to get 390.
Bring next digit (9) of the dividend behind the 390 and repeat the process: 3909 / 480

On to step 4:
480 can be fit into 3909 8 times, resulting in a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 3840 from 3909, we get 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 480

Advancing to step 5:
480 goes into 697 1 times with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtract 480 from 697 to get 217.
Include the next digit (6) from the dividend after 217, then repeat: 2176 / 480

On to step 6:
480 can be fit into 2176 4 times, resulting in a remainder of 256.
The next digit of our result is 4. 
Result so far: 1814.0
Subtract 1920 from 2176 to get 256.
Fetch the next digit (0) from the dividend, attach it to 256 and continue: 2560 / 480

Step 7:
2560 divided by 480 is 5 with a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 18145.0
Subtract 2400 from 2560 to get 160.
Fetch the next digit (9) from the dividend, attach it to 160 and continue: 1609 / 480

Going ahead to step 8:
When dividing 1609 by 480, we get 3 with a remainder of 169.
The next digit of our result is 3. 
Result so far: 181453.0
Subtracting 1440 from 1609 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 9:
480 goes into 1690 3 times with a remainder of 250.
The next digit of our result is 3. 
Result so far: 181453.3
If we take 1440 away from 1690, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
If we divide 2500 by 480, we get 5 and a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 181453.35
If we take 2400 away from 2500, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 480 fits into 1000 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 181453.352
The remainder is 40 after subtracting 960 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 480, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 181453.352
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 13:
480 goes into 4000 8 times with a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 181453.35208
If we take 3840 away from 4000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
480 goes into 1600 3 times with a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 181453.352083
The remainder is 160 after subtracting 1440 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
If we divide 1600 by 480, we get 3 and a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 181453.3520833
If we take 1440 away from 1600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 181453.3520833 with a remainder of 1.6e-06.
