We look at the division of 871243 by 74 
We want to divide 871243 by 74.

Moving on to step 1:
The number 74 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 74

Step 2:
74 goes into 87 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 74 from 87 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 74

Let's proceed to step 3:
74 goes into 131 1 times with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 74 from 131 to get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 74

On to step 4:
When dividing 572 by 74, we get 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 117.0
If we take 518 away from 572, we end up with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 74

Step 5:
544 divided by 74 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 1177.0
If we subtract 518 from 544, we get 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 74

Let's proceed to step 6:
74 goes into 263 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 11773.0
Subtracting 222 from 263 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
The number 74 fits into 410 5 times, leaving a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 11773.5
If we take 370 away from 410, we end up 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.

Step 8:
74 goes into 400 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11773.55
The remainder is 30 after subtracting 370 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 11773.55, with a leftover of 0.03.
