We're dividing 12930753 by 304 
We want to divide 12930753 by 304.

On to step 1:
1 divided by 304 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 304

Advancing to step 2:
If we divide 12 by 304, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 304

Let's proceed to step 3:
304 goes into 129 0 times with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 129, we end up with 129.
Take the next digit (3) from the dividend and append it to 129, then repeat: 1293 / 304

Step 4:
304 can be fit into 1293 4 times, resulting in a remainder of 77.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1216 from 1293 leaves us with 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 304

Moving on to step 5:
If we divide 770 by 304, we get 2 and a remainder of 162.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 608 from 770 and we're left with 162.
Bring next digit (7) of the dividend behind the 162 and repeat the process: 1627 / 304

Advancing to step 6:
304 goes into 1627 5 times with a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 425.0
If we subtract 1520 from 1627, we get 107.
Append the next digit (5) from the dividend to 107 and continue with: 1075 / 304

On to step 7:
304 can be fit into 1075 3 times, resulting in a remainder of 163.
Write down 3 as next digit of the result. 
Result so far: 4253.0
Subtracting 912 from 1075 leaves us with 163.
Fetch the next digit (3) from the dividend, attach it to 163 and continue: 1633 / 304

Let's proceed to step 8:
If we divide 1633 by 304, we get 5 and a remainder of 113.
The number 5 becomes the next digit in our result. 
Result so far: 42535.0
If we subtract 1520 from 1633, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
304 goes into 1130 3 times with a remainder of 218.
The next digit of our result is 3. 
Result so far: 42535.3
If we take 912 away from 1130, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
If we divide 2180 by 304, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 42535.37
Subtract 2128 from 2180 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
The number 304 fits into 520 1 times, leaving a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 42535.371
Deduct 304 from 520 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
If we divide 2160 by 304, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 42535.3717
If we take 2128 away from 2160, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
304 can be fit into 320 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 42535.37171
Subtracting 304 from 320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
304 goes into 160 0 times with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 42535.37171
Deduct 0 from 160 and we're left 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.

Advancing to step 15:
If we divide 1600 by 304, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 42535.3717105
The remainder is 80 after subtracting 1520 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
The number 304 fits into 800 2 times, leaving a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 42535.37171052
If we take 608 away from 800, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 42535.37171052 and a remainder of 1.92e-07.
