42391307 ÷ 582 
We're looking to find how many times 582 goes into 42391307.

On to step 1:
If we divide 4 by 582, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 582

Moving on to step 2:
The number 582 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 582

Let's proceed to step 3:
If we divide 423 by 582, we get 0 and a remainder of 423.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 423 after subtracting 0 from 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 582

Going ahead to step 4:
582 can be fit into 4239 7 times, resulting in a remainder of 165.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 165 after subtracting 4074 from 4239.
Fetch the next digit (1) from the dividend, attach it to 165 and continue: 1651 / 582

Moving on to step 5:
The number 582 fits into 1651 2 times, leaving a remainder of 487.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 1164 from 1651 to get 487.
Include the next digit (3) from the dividend after 487, then repeat: 4873 / 582

Let's proceed to step 6:
When dividing 4873 by 582, we get 8 with a remainder of 217.
Use 8 as the next digit of our solution. 
Result so far: 728.0
Deduct 4656 from 4873 and we're left with 217.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 582

Let's proceed to step 7:
582 can be fit into 2170 3 times, resulting in a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 7283.0
Subtract 1746 from 2170 to get 424.
Append the next digit (7) from the dividend to 424 and continue with: 4247 / 582

Let's proceed to step 8:
4247 divided by 582 is 7 with a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 72837.0
The remainder is 173 after subtracting 4074 from 4247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 9:
582 can be fit into 1730 2 times, resulting in a remainder of 566.
Use 2 as the next digit of our solution. 
Result so far: 72837.2
Deduct 1164 from 1730 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 10:
The number 582 fits into 5660 9 times, leaving a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 72837.29
Subtracting 5238 from 5660 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 11:
582 can be fit into 4220 7 times, resulting in a remainder of 146.
The next digit of our result is 7. 
Result so far: 72837.297
Subtract 4074 from 4220 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 12:
582 can be fit into 1460 2 times, resulting in a remainder of 296.
Write down 2 as next digit of the result. 
Result so far: 72837.2972
If we take 1164 away from 1460, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 13:
When dividing 2960 by 582, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 72837.29725
If we take 2910 away from 2960, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 582, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 72837.29725
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 15:
If we divide 5000 by 582, we get 8 and a remainder of 344.
The next digit of our result is 8. 
Result so far: 72837.2972508
Subtract 4656 from 5000 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 16:
582 can be fit into 3440 5 times, resulting in a remainder of 530.
The number 5 becomes the next digit in our result. 
Result so far: 72837.29725085
Deduct 2910 from 3440 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Our division results in 72837.29725085 with a remaining 5.3e-07.
