We look at the division of 81669164 by 287 
Our goal is to divide 81669164 by 287.

Going ahead to step 1:
8 divided by 287 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 287

Step 2:
287 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 287

On to step 3:
287 can be fit into 816 2 times, resulting in a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 574 from 816 leaves us with 242.
Append the next digit (6) from the dividend to 242 and continue with: 2426 / 287

Going ahead to step 4:
2426 divided by 287 is 8 with a remainder of 130.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 2296 away from 2426, we end up with 130.
Fetch the next digit (9) from the dividend, attach it to 130 and continue: 1309 / 287

Going ahead to step 5:
The number 287 fits into 1309 4 times, leaving a remainder of 161.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
If we take 1148 away from 1309, we end up with 161.
Grab the next digit (1) from the dividend, add it to 161, then carry on: 1611 / 287

Let's proceed to step 6:
When dividing 1611 by 287, we get 5 with a remainder of 176.
Record the quotient 5 as the next digit in the result. 
Result so far: 2845.0
Deduct 1435 from 1611 and we're left with 176.
Include the next digit (6) from the dividend after 176, then repeat: 1766 / 287

Advancing to step 7:
287 goes into 1766 6 times with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 28456.0
Subtracting 1722 from 1766 leaves us with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 287

Advancing to step 8:
287 goes into 444 1 times with a remainder of 157.
Write down 1 as next digit of the result. 
Result so far: 284561.0
If we subtract 287 from 444, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
When dividing 1570 by 287, we get 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 284561.5
If we take 1435 away from 1570, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
1350 divided by 287 is 4 with a remainder of 202.
Record the quotient 4 as the next digit in the result. 
Result so far: 284561.54
If we subtract 1148 from 1350, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 11:
2020 divided by 287 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 284561.547
The remainder is 11 after subtracting 2009 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
287 goes into 110 0 times with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 284561.547
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 13:
287 can be fit into 1100 3 times, resulting in a remainder of 239.
Record the quotient 3 as the next digit in the result. 
Result so far: 284561.54703
Subtracting 861 from 1100 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 14:
When dividing 2390 by 287, we get 8 with a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 284561.547038
Subtract 2296 from 2390 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 15:
The number 287 fits into 940 3 times, leaving a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 284561.5470383
Subtracting 861 from 940 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 16:
If we divide 790 by 287, we get 2 and a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 284561.54703832
Deduct 574 from 790 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 284561.54703832 and a remainder of 2.16e-07.
