80297145 divided by 285 
We want to divide 80297145 by 285.

Going ahead to step 1:
The number 285 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 285

Let's proceed to step 2:
80 divided by 285 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 285

Let's proceed to step 3:
285 goes into 802 2 times with a remainder of 232.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 570 from 802 and we're left with 232.
Bring next digit (9) of the dividend behind the 232 and repeat the process: 2329 / 285

Advancing to step 4:
When dividing 2329 by 285, we get 8 with a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 2280 from 2329, we get 49.
Include the next digit (7) from the dividend after 49, then repeat: 497 / 285

Going ahead to step 5:
285 can be fit into 497 1 times, resulting in a remainder of 212.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
If we subtract 285 from 497, we get 212.
Take the next digit (1) from the dividend and append it to 212, then repeat: 2121 / 285

Let's proceed to step 6:
The number 285 fits into 2121 7 times, leaving a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 2817.0
Deduct 1995 from 2121 and we're left with 126.
Fetch the next digit (4) from the dividend, attach it to 126 and continue: 1264 / 285

Going ahead to step 7:
285 goes into 1264 4 times with a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 28174.0
Subtract 1140 from 1264 to get 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 285

Going ahead to step 8:
285 can be fit into 1245 4 times, resulting in a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 281744.0
If we take 1140 away from 1245, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 9:
285 goes into 1050 3 times with a remainder of 195.
Write down 3 as next digit of the result. 
Result so far: 281744.3
Subtracting 855 from 1050 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 10:
1950 divided by 285 is 6 with a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 281744.36
If we take 1710 away from 1950, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
The number 285 fits into 2400 8 times, leaving a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 281744.368
Deduct 2280 from 2400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 285 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 281744.3684
Subtracting 1140 from 1200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 285 fits into 600 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 281744.36842
Subtract 570 from 600 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
When dividing 300 by 285, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 281744.368421
Subtract 285 from 300 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.

Step 15:
285 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 281744.368421
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
1500 divided by 285 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 281744.36842105
If we subtract 1425 from 1500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 281744.36842105, with a leftover of 7.5e-08.
