86247722 ÷ 287 
Our goal is to divide 86247722 by 287.

On to step 1:
287 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 287

Advancing to step 2:
When dividing 86 by 287, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 287

Let's proceed to step 3:
287 goes into 862 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 861 from 862 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 287

Step 4:
When dividing 14 by 287, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 14, we get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 287

On to step 5:
147 divided by 287 is 0 with a remainder of 147.
The next digit of our result is 0. 
Result so far: 300.0
Subtracting 0 from 147 leaves us with 147.
Fetch the next digit (7) from the dividend, attach it to 147 and continue: 1477 / 287

Advancing to step 6:
1477 divided by 287 is 5 with a remainder of 42.
Record the quotient 5 as the next digit in the result. 
Result so far: 3005.0
If we take 1435 away from 1477, we end up with 42.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 287

Moving on to step 7:
The number 287 fits into 422 1 times, leaving a remainder of 135.
The next digit of our result is 1. 
Result so far: 30051.0
Deduct 287 from 422 and we're left with 135.
Include the next digit (2) from the dividend after 135, then repeat: 1352 / 287

Step 8:
1352 divided by 287 is 4 with a remainder of 204.
Put 4 as the next digit of the answer. 
Result so far: 300514.0
If we subtract 1148 from 1352, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 9:
287 goes into 2040 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 300514.7
Subtracting 2009 from 2040 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 10:
287 can be fit into 310 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 300514.71
Subtract 287 from 310 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
The number 287 fits into 230 0 times, leaving a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 300514.71
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
287 can be fit into 2300 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 300514.7108
If we subtract 2296 from 2300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
287 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 300514.7108
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
If we divide 400 by 287, we get 1 and a remainder of 113.
The next digit of our result is 1. 
Result so far: 300514.710801
Deduct 287 from 400 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Going ahead to step 15:
The number 287 fits into 1130 3 times, leaving a remainder of 269.
Put 3 as the next digit of the answer. 
Result so far: 300514.7108013
If we take 861 away from 1130, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 16:
If we divide 2690 by 287, we get 9 and a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 300514.71080139
If we take 2583 away from 2690, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

In conclusion, the division gives 300514.71080139 with a balance of 1.07e-07.
