We're dividing 31439029 by 480 
We want to figure out the number of times 31439029 can be divided by 480.

Advancing to step 1:
The number 480 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 480

Moving on to step 2:
The number 480 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 480

Moving on to step 3:
480 goes into 314 0 times with a remainder of 314.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 314, we end up with 314.
Take the next digit (3) from the dividend and append it to 314, then repeat: 3143 / 480

Going ahead to step 4:
The number 480 fits into 3143 6 times, leaving a remainder of 263.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2880 from 3143 to get 263.
Grab the next digit (9) from the dividend, add it to 263, then carry on: 2639 / 480

Let's proceed to step 5:
480 goes into 2639 5 times with a remainder of 239.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 2400 from 2639 leaves us with 239.
Include the next digit (0) from the dividend after 239, then repeat: 2390 / 480

Advancing to step 6:
When dividing 2390 by 480, we get 4 with a remainder of 470.
Put 4 as the next digit of the answer. 
Result so far: 654.0
Subtract 1920 from 2390 to get 470.
Fetch the next digit (2) from the dividend, attach it to 470 and continue: 4702 / 480

Going ahead to step 7:
480 can be fit into 4702 9 times, resulting in a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 6549.0
If we take 4320 away from 4702, we end up with 382.
Take the next digit (9) from the dividend and append it to 382, then repeat: 3829 / 480

Advancing to step 8:
The number 480 fits into 3829 7 times, leaving a remainder of 469.
The number 7 becomes the next digit in our result. 
Result so far: 65497.0
The remainder is 469 after subtracting 3360 from 3829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

On to step 9:
480 can be fit into 4690 9 times, resulting in a remainder of 370.
The next digit of our result is 9. 
Result so far: 65497.9
The remainder is 370 after subtracting 4320 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 10:
If we divide 3700 by 480, we get 7 and a remainder of 340.
Put 7 as the next digit of the answer. 
Result so far: 65497.97
Subtracting 3360 from 3700 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 11:
The number 480 fits into 3400 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 65497.977
Subtract 3360 from 3400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 65497.977, and the remainder is 0.004.
