40086268 ÷ 582 
Our goal is to divide 40086268 by 582.

Let's proceed to step 1:
582 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 582

Advancing to step 2:
40 divided by 582 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 582

On to step 3:
582 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 400 leaves us with 400.
Grab the next digit (8) from the dividend, add it to 400, then carry on: 4008 / 582

Going ahead to step 4:
The number 582 fits into 4008 6 times, leaving a remainder of 516.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 3492 from 4008, we get 516.
Append the next digit (6) from the dividend to 516 and continue with: 5166 / 582

On to step 5:
If we divide 5166 by 582, we get 8 and a remainder of 510.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 4656 from 5166 leaves us with 510.
Bring next digit (2) of the dividend behind the 510 and repeat the process: 5102 / 582

Let's proceed to step 6:
582 can be fit into 5102 8 times, resulting in a remainder of 446.
The number 8 becomes the next digit in our result. 
Result so far: 688.0
Subtract 4656 from 5102 to get 446.
Include the next digit (6) from the dividend after 446, then repeat: 4466 / 582

Step 7:
582 can be fit into 4466 7 times, resulting in a remainder of 392.
The next digit of our result is 7. 
Result so far: 6887.0
If we take 4074 away from 4466, we end up with 392.
Fetch the next digit (8) from the dividend, attach it to 392 and continue: 3928 / 582

Advancing to step 8:
3928 divided by 582 is 6 with a remainder of 436.
Use 6 as the next digit of our solution. 
Result so far: 68876.0
If we take 3492 away from 3928, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
4360 divided by 582 is 7 with a remainder of 286.
The number 7 becomes the next digit in our result. 
Result so far: 68876.7
If we subtract 4074 from 4360, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 10:
If we divide 2860 by 582, we get 4 and a remainder of 532.
Put 4 as the next digit of the answer. 
Result so far: 68876.74
The remainder is 532 after subtracting 2328 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 11:
582 can be fit into 5320 9 times, resulting in a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 68876.749
Subtract 5238 from 5320 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 12:
When dividing 820 by 582, we get 1 with a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 68876.7491
If we subtract 582 from 820, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 13:
If we divide 2380 by 582, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 68876.74914
Deduct 2328 from 2380 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
When dividing 520 by 582, we get 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 68876.74914
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 15:
582 goes into 5200 8 times with a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 68876.7491408
If we subtract 4656 from 5200, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 16:
If we divide 5440 by 582, we get 9 and a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 68876.74914089
If we subtract 5238 from 5440, 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.

After the division, we end up with 68876.74914089 and a remainder of 2.02e-07.
