15980821 divided by 304 
Our goal is to divide 15980821 by 304.

Advancing to step 1:
The number 304 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 304

Moving on to step 2:
15 divided by 304 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 304

Going ahead to step 3:
If we divide 159 by 304, we get 0 and a remainder of 159.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Fetch the next digit (8) from the dividend, attach it to 159 and continue: 1598 / 304

Going ahead to step 4:
304 goes into 1598 5 times with a remainder of 78.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1520 away from 1598, we end up with 78.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 304

Moving on to step 5:
The number 304 fits into 780 2 times, leaving a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we take 608 away from 780, we end up with 172.
Include the next digit (8) from the dividend after 172, then repeat: 1728 / 304

Going ahead to step 6:
If we divide 1728 by 304, we get 5 and a remainder of 208.
The next digit of our result is 5. 
Result so far: 525.0
The remainder is 208 after subtracting 1520 from 1728.
Append the next digit (2) from the dividend to 208 and continue with: 2082 / 304

On to step 7:
304 goes into 2082 6 times with a remainder of 258.
Use 6 as the next digit of our solution. 
Result so far: 5256.0
If we subtract 1824 from 2082, we get 258.
Bring next digit (1) of the dividend behind the 258 and repeat the process: 2581 / 304

Step 8:
304 can be fit into 2581 8 times, resulting in a remainder of 149.
Write down 8 as next digit of the result. 
Result so far: 52568.0
Subtract 2432 from 2581 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 9:
When dividing 1490 by 304, we get 4 with a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 52568.4
Subtract 1216 from 1490 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 10:
304 goes into 2740 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 52568.49
If we take 2736 away from 2740, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
40 divided by 304 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 52568.49
Subtract 0 from 40 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.

On to step 12:
304 can be fit into 400 1 times, resulting in a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 52568.4901
If we subtract 304 from 400, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
304 goes into 960 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 52568.49013
The remainder is 48 after subtracting 912 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
If we divide 480 by 304, we get 1 and a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 52568.490131
If we take 304 away from 480, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 15:
1760 divided by 304 is 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 52568.4901315
The remainder is 240 after subtracting 1520 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
If we divide 2400 by 304, we get 7 and a remainder of 272.
Put 7 as the next digit of the answer. 
Result so far: 52568.49013157
If we subtract 2128 from 2400, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final outcome is 52568.49013157, with a leftover of 2.72e-07.
