Let's divide 31830321 by 480
We're looking to find how many times 480 goes into 31830321.

Going ahead to step 1:
The number 480 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 480

Advancing to step 2:
31 divided by 480 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 480

Advancing to step 3:
If we divide 318 by 480, we get 0 and a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 318 and we're left with 318.
Include the next digit (3) from the dividend after 318, then repeat: 3183 / 480

Moving on to step 4:
480 goes into 3183 6 times with a remainder of 303.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2880 from 3183 to get 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 480

Advancing to step 5:
If we divide 3030 by 480, we get 6 and a remainder of 150.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtracting 2880 from 3030 leaves us with 150.
Take the next digit (3) from the dividend and append it to 150, then repeat: 1503 / 480

On to step 6:
480 can be fit into 1503 3 times, resulting in a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 663.0
Subtract 1440 from 1503 to get 63.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 480

Step 7:
The number 480 fits into 632 1 times, leaving a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 6631.0
If we subtract 480 from 632, we get 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 480

Going ahead to step 8:
1521 divided by 480 is 3 with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 66313.0
Subtract 1440 from 1521 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
The number 480 fits into 810 1 times, leaving a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 66313.1
Subtracting 480 from 810 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 10:
480 can be fit into 3300 6 times, resulting in a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 66313.16
If we subtract 2880 from 3300, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 11:
If we divide 4200 by 480, we get 8 and a remainder of 360.
The next digit of our result is 8. 
Result so far: 66313.168
If we take 3840 away from 4200, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
480 can be fit into 3600 7 times, resulting in a remainder of 240.
Record the quotient 7 as the next digit in the result. 
Result so far: 66313.1687
Deduct 3360 from 3600 and we're left 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.

Step 13:
480 goes into 2400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 66313.16875
Subtract 2400 from 2400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
When dividing 0 by 480, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66313.16875
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.

Advancing 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: 66313.16875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 66313.16875 with a remaining 0.0.
