Let's divide 80169414 by 647
We want to figure out the number of times 80169414 can be divided by 647.

Moving on to step 1:
The number 647 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 647

On to step 2:
647 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 647

On to step 3:
When dividing 801 by 647, we get 1 with a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 647 away from 801, we end up with 154.
Bring next digit (6) of the dividend behind the 154 and repeat the process: 1546 / 647

Let's proceed to step 4:
When dividing 1546 by 647, we get 2 with a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1294 from 1546, we get 252.
Bring next digit (9) of the dividend behind the 252 and repeat the process: 2529 / 647

Going ahead to step 5:
647 goes into 2529 3 times with a remainder of 588.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 1941 from 2529 and we're left with 588.
Grab the next digit (4) from the dividend, add it to 588, then carry on: 5884 / 647

Going ahead to step 6:
If we divide 5884 by 647, we get 9 and a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 1239.0
If we subtract 5823 from 5884, we get 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 647

Going ahead to step 7:
647 can be fit into 611 0 times, resulting in a remainder of 611.
Write down 0 as next digit of the result. 
Result so far: 12390.0
If we take 0 away from 611, we end up with 611.
Fetch the next digit (4) from the dividend, attach it to 611 and continue: 6114 / 647

Step 8:
6114 divided by 647 is 9 with a remainder of 291.
The next digit of our result is 9. 
Result so far: 123909.0
The remainder is 291 after subtracting 5823 from 6114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 9:
When dividing 2910 by 647, we get 4 with a remainder of 322.
The number 4 becomes the next digit in our result. 
Result so far: 123909.4
The remainder is 322 after subtracting 2588 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 10:
3220 divided by 647 is 4 with a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 123909.44
Subtracting 2588 from 3220 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The final outcome is 123909.44, with a leftover of 0.632.
