30789481 divided by 312 
Let's see how many times 312 fits into 30789481.

Moving on to step 1:
When dividing 3 by 312, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 312

Moving on to step 2:
The number 312 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 312

Let's proceed to step 3:
If we divide 307 by 312, we get 0 and a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 307, we end up with 307.
Bring next digit (8) of the dividend behind the 307 and repeat the process: 3078 / 312

Let's proceed to step 4:
When dividing 3078 by 312, we get 9 with a remainder of 270.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 2808 from 3078 to get 270.
Grab the next digit (9) from the dividend, add it to 270, then carry on: 2709 / 312

Moving on to step 5:
The number 312 fits into 2709 8 times, leaving a remainder of 213.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we subtract 2496 from 2709, we get 213.
Fetch the next digit (4) from the dividend, attach it to 213 and continue: 2134 / 312

On to step 6:
2134 divided by 312 is 6 with a remainder of 262.
The next digit of our result is 6. 
Result so far: 986.0
Deduct 1872 from 2134 and we're left with 262.
Grab the next digit (8) from the dividend, add it to 262, then carry on: 2628 / 312

Step 7:
312 goes into 2628 8 times with a remainder of 132.
The next digit of our result is 8. 
Result so far: 9868.0
Subtracting 2496 from 2628 leaves us with 132.
Take the next digit (1) from the dividend and append it to 132, then repeat: 1321 / 312

Step 8:
The number 312 fits into 1321 4 times, leaving a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 98684.0
Subtract 1248 from 1321 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
If we divide 730 by 312, we get 2 and a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 98684.2
Subtract 624 from 730 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 10:
312 can be fit into 1060 3 times, resulting in a remainder of 124.
Record the quotient 3 as the next digit in the result. 
Result so far: 98684.23
Subtract 936 from 1060 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 11:
1240 divided by 312 is 3 with a remainder of 304.
Write down 3 as next digit of the result. 
Result so far: 98684.233
Deduct 936 from 1240 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The quotient of the division is 98684.233, and the remainder is 0.0304.
