80631447 ÷ 204 
We want to divide 80631447 by 204.

Moving on to step 1:
204 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 204

Advancing to step 2:
204 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (6) of the dividend behind the 80 and repeat the process: 806 / 204

Let's proceed to step 3:
The number 204 fits into 806 3 times, leaving a remainder of 194.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 194 after subtracting 612 from 806.
Fetch the next digit (3) from the dividend, attach it to 194 and continue: 1943 / 204

Going ahead to step 4:
1943 divided by 204 is 9 with a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 107 after subtracting 1836 from 1943.
Include the next digit (1) from the dividend after 107, then repeat: 1071 / 204

Let's proceed to step 5:
If we divide 1071 by 204, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 395.0
The remainder is 51 after subtracting 1020 from 1071.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 204

Moving on to step 6:
204 goes into 514 2 times with a remainder of 106.
The next digit of our result is 2. 
Result so far: 3952.0
Subtract 408 from 514 to get 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 204

Advancing to step 7:
204 goes into 1064 5 times with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 39525.0
Deduct 1020 from 1064 and we're left with 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 204

Let's proceed to step 8:
When dividing 447 by 204, we get 2 with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 395252.0
Subtracting 408 from 447 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
204 goes into 390 1 times with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 395252.1
Subtracting 204 from 390 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
204 can be fit into 1860 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 395252.19
The remainder is 24 after subtracting 1836 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
204 goes into 240 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 395252.191
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 204 is 1 with a remainder of 156.
Record the quotient 1 as the next digit in the result. 
Result so far: 395252.1911
If we subtract 204 from 360, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final outcome is 395252.1911, with a leftover of 0.00156.
