We're dividing 42339539 by 871 
Let's see how many times 871 fits into 42339539.

Moving on to step 1:
871 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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 871

Advancing to step 2:
871 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 871

Going ahead to step 3:
871 can be fit into 423 0 times, resulting in a remainder of 423.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 423, we end up with 423.
Bring next digit (3) of the dividend behind the 423 and repeat the process: 4233 / 871

Going ahead to step 4:
871 goes into 4233 4 times with a remainder of 749.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 749 after subtracting 3484 from 4233.
Bring next digit (9) of the dividend behind the 749 and repeat the process: 7499 / 871

Let's proceed to step 5:
871 can be fit into 7499 8 times, resulting in a remainder of 531.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we take 6968 away from 7499, we end up with 531.
Grab the next digit (5) from the dividend, add it to 531, then carry on: 5315 / 871

Going ahead to step 6:
871 goes into 5315 6 times with a remainder of 89.
Use 6 as the next digit of our solution. 
Result so far: 486.0
If we subtract 5226 from 5315, we get 89.
Include the next digit (3) from the dividend after 89, then repeat: 893 / 871

Let's proceed to step 7:
893 divided by 871 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 4861.0
If we take 871 away from 893, we end up with 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 871

Advancing to step 8:
If we divide 229 by 871, we get 0 and a remainder of 229.
Put 0 as the next digit of the answer. 
Result so far: 48610.0
Subtract 0 from 229 to get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Step 9:
When dividing 2290 by 871, we get 2 with a remainder of 548.
The number 2 becomes the next digit in our result. 
Result so far: 48610.2
If we subtract 1742 from 2290, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 10:
871 goes into 5480 6 times with a remainder of 254.
Write down 6 as next digit of the result. 
Result so far: 48610.26
If we subtract 5226 from 5480, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 11:
871 can be fit into 2540 2 times, resulting in a remainder of 798.
Use 2 as the next digit of our solution. 
Result so far: 48610.262
Subtracting 1742 from 2540 leaves us with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Going ahead to step 12:
When dividing 7980 by 871, we get 9 with a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 48610.2629
Subtract 7839 from 7980 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 13:
The number 871 fits into 1410 1 times, leaving a remainder of 539.
Use 1 as the next digit of our solution. 
Result so far: 48610.26291
Subtract 871 from 1410 to get 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Advancing to step 14:
The number 871 fits into 5390 6 times, leaving a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 48610.262916
Deduct 5226 from 5390 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 15:
The number 871 fits into 1640 1 times, leaving a remainder of 769.
Write down 1 as next digit of the result. 
Result so far: 48610.2629161
Subtracting 871 from 1640 leaves us with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Moving on to step 16:
If we divide 7690 by 871, we get 8 and a remainder of 722.
Use 8 as the next digit of our solution. 
Result so far: 48610.26291618
Subtracting 6968 from 7690 leaves us with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

After the division, we end up with 48610.26291618 and a remainder of 7.22e-07.
