80564389 divided by 305 
Our goal is to divide 80564389 by 305.

Advancing to step 1:
The number 305 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 305

Advancing to step 2:
When dividing 80 by 305, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 305

On to step 3:
305 can be fit into 805 2 times, resulting in a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 610 away from 805, we end up with 195.
Grab the next digit (6) from the dividend, add it to 195, then carry on: 1956 / 305

Moving on to step 4:
When dividing 1956 by 305, we get 6 with a remainder of 126.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 126 after subtracting 1830 from 1956.
Fetch the next digit (4) from the dividend, attach it to 126 and continue: 1264 / 305

Let's proceed to step 5:
The number 305 fits into 1264 4 times, leaving a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 264.0
If we take 1220 away from 1264, we end up with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 305

Moving on to step 6:
305 goes into 443 1 times with a remainder of 138.
The next digit of our result is 1. 
Result so far: 2641.0
The remainder is 138 after subtracting 305 from 443.
Bring next digit (8) of the dividend behind the 138 and repeat the process: 1388 / 305

Going ahead to step 7:
The number 305 fits into 1388 4 times, leaving a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 26414.0
If we take 1220 away from 1388, we end up with 168.
Fetch the next digit (9) from the dividend, attach it to 168 and continue: 1689 / 305

Advancing to step 8:
When dividing 1689 by 305, we get 5 with a remainder of 164.
The number 5 becomes the next digit in our result. 
Result so far: 264145.0
Subtract 1525 from 1689 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 9:
305 goes into 1640 5 times with a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 264145.5
Subtracting 1525 from 1640 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 10:
The number 305 fits into 1150 3 times, leaving a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 264145.53
If we take 915 away from 1150, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 11:
If we divide 2350 by 305, we get 7 and a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 264145.537
Subtracting 2135 from 2350 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 12:
2150 divided by 305 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 264145.5377
Subtract 2135 from 2150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 264145.5377 with a remainder of 0.00015.
