We're dividing 39345783 by 304 
Our goal is to divide 39345783 by 304.

Advancing to step 1:
304 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 304

Step 2:
The number 304 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 304

Step 3:
304 goes into 393 1 times with a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 304 away from 393, we end up with 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 304

On to step 4:
If we divide 894 by 304, we get 2 and a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 608 from 894 and we're left with 286.
Append the next digit (5) from the dividend to 286 and continue with: 2865 / 304

Step 5:
2865 divided by 304 is 9 with a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 2736 from 2865 to get 129.
Include the next digit (7) from the dividend after 129, then repeat: 1297 / 304

Going ahead to step 6:
304 can be fit into 1297 4 times, resulting in a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
The remainder is 81 after subtracting 1216 from 1297.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 304

Moving on to step 7:
The number 304 fits into 818 2 times, leaving a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 12942.0
Subtract 608 from 818 to get 210.
Bring next digit (3) of the dividend behind the 210 and repeat the process: 2103 / 304

Let's proceed to step 8:
When dividing 2103 by 304, we get 6 with a remainder of 279.
The number 6 becomes the next digit in our result. 
Result so far: 129426.0
The remainder is 279 after subtracting 1824 from 2103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 9:
The number 304 fits into 2790 9 times, leaving a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 129426.9
The remainder is 54 after subtracting 2736 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
540 divided by 304 is 1 with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 129426.91
If we take 304 away from 540, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 11:
When dividing 2360 by 304, we get 7 with a remainder of 232.
The next digit of our result is 7. 
Result so far: 129426.917
Subtracting 2128 from 2360 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 12:
The number 304 fits into 2320 7 times, leaving a remainder of 192.
Write down 7 as next digit of the result. 
Result so far: 129426.9177
Deduct 2128 from 2320 and we're left 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.

The final result is 129426.9177 with a remainder of 0.00192.
