70286391 ÷ 480 
We're looking to find how many times 480 goes into 70286391.

Moving on to step 1:
The number 480 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 480

Moving on to step 2:
480 can be fit into 70 0 times, resulting in a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 480

Moving on to step 3:
480 can be fit into 702 1 times, resulting in a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 480 away from 702, we end up with 222.
Include the next digit (8) from the dividend after 222, then repeat: 2228 / 480

Moving on to step 4:
480 goes into 2228 4 times with a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 1920 from 2228, we get 308.
Bring next digit (6) of the dividend behind the 308 and repeat the process: 3086 / 480

Step 5:
3086 divided by 480 is 6 with a remainder of 206.
Write down 6 as next digit of the result. 
Result so far: 146.0
The remainder is 206 after subtracting 2880 from 3086.
Bring next digit (3) of the dividend behind the 206 and repeat the process: 2063 / 480

Step 6:
The number 480 fits into 2063 4 times, leaving a remainder of 143.
Use 4 as the next digit of our solution. 
Result so far: 1464.0
If we subtract 1920 from 2063, we get 143.
Include the next digit (9) from the dividend after 143, then repeat: 1439 / 480

On to step 7:
480 goes into 1439 2 times with a remainder of 479.
Use 2 as the next digit of our solution. 
Result so far: 14642.0
Subtract 960 from 1439 to get 479.
Bring next digit (1) of the dividend behind the 479 and repeat the process: 4791 / 480

Moving on to step 8:
The number 480 fits into 4791 9 times, leaving a remainder of 471.
Write down 9 as next digit of the result. 
Result so far: 146429.0
Subtract 4320 from 4791 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 9:
4710 divided by 480 is 9 with a remainder of 390.
The number 9 becomes the next digit in our result. 
Result so far: 146429.9
If we take 4320 away from 4710, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
480 can be fit into 3900 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 146429.98
The remainder is 60 after subtracting 3840 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
The number 480 fits into 600 1 times, leaving a remainder of 120.
The next digit of our result is 1. 
Result so far: 146429.981
If we take 480 away from 600, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
The number 480 fits into 1200 2 times, leaving a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 146429.9812
Subtracting 960 from 1200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
When dividing 2400 by 480, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 146429.98125
The remainder is 0 after subtracting 2400 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
The number 480 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 146429.98125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
480 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 146429.98125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 146429.98125 with a remainder of 0.0.
