Let's divide 87881 by 70
We want to divide 87881 by 70.

Advancing to step 1:
70 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 70

Going ahead to step 2:
If we divide 87 by 70, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 70 from 87 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 70

Step 3:
70 goes into 178 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 140 away from 178, we end up with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 70

On to step 4:
70 goes into 388 5 times with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 350 from 388, we get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 70

Moving on to step 5:
381 divided by 70 is 5 with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we subtract 350 from 381, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 6:
If we divide 310 by 70, we get 4 and a remainder of 30.
The next digit of our result is 4. 
Result so far: 1255.4
Subtract 280 from 310 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1255.44
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1255.44, and the remainder is 0.02.
