42571065 ÷ 839 
Let's see how many times 839 fits into 42571065.

Going ahead to step 1:
839 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 839

Advancing to step 2:
839 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 839

Advancing to step 3:
If we divide 425 by 839, we get 0 and a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 425, we get 425.
Bring next digit (7) of the dividend behind the 425 and repeat the process: 4257 / 839

Step 4:
839 goes into 4257 5 times with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 4195 from 4257 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 839

Going ahead to step 5:
839 goes into 621 0 times with a remainder of 621.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 621 leaves us with 621.
Grab the next digit (0) from the dividend, add it to 621, then carry on: 6210 / 839

Going ahead to step 6:
6210 divided by 839 is 7 with a remainder of 337.
Use 7 as the next digit of our solution. 
Result so far: 507.0
If we take 5873 away from 6210, we end up with 337.
Append the next digit (6) from the dividend to 337 and continue with: 3376 / 839

Let's proceed to step 7:
3376 divided by 839 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 5074.0
If we take 3356 away from 3376, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 839

Going ahead to step 8:
205 divided by 839 is 0 with a remainder of 205.
The number 0 becomes the next digit in our result. 
Result so far: 50740.0
The remainder is 205 after subtracting 0 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 9:
839 can be fit into 2050 2 times, resulting in a remainder of 372.
The number 2 becomes the next digit in our result. 
Result so far: 50740.2
Subtracting 1678 from 2050 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
When dividing 3720 by 839, we get 4 with a remainder of 364.
The next digit of our result is 4. 
Result so far: 50740.24
Deduct 3356 from 3720 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
839 goes into 3640 4 times with a remainder of 284.
The number 4 becomes the next digit in our result. 
Result so far: 50740.244
Subtracting 3356 from 3640 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 50740.244 with a remaining 0.0284.
