We're dividing 870150 by 71 
Let's see how many times 71 fits into 870150.

Going ahead to step 1:
8 divided by 71 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 71

Step 2:
When dividing 87 by 71, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 71 from 87 leaves us with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 71

Let's proceed to step 3:
When dividing 160 by 71, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 142 from 160 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 71

Let's proceed to step 4:
If we divide 181 by 71, we get 2 and a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 142 from 181, we get 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 71

Step 5:
When dividing 395 by 71, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 1225.0
If we take 355 away from 395, we end up with 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 71

Moving on to step 6:
The number 71 fits into 400 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 12255.0
If we subtract 355 from 400, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
If we divide 450 by 71, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 12255.6
The remainder is 24 after subtracting 426 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
If we divide 240 by 71, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 12255.63
If we take 213 away from 240, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
71 goes into 270 3 times with a remainder of 57.
The next digit of our result is 3. 
Result so far: 12255.633
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final result is 12255.633 with a remainder of 0.0057.
