Let's divide 378871 by 70
We're looking to find how many times 70 goes into 378871.

On to step 1:
70 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 70

Step 2:
37 divided by 70 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 70

Let's proceed to step 3:
70 can be fit into 378 5 times, resulting in a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 28 after subtracting 350 from 378.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 70

Moving on to step 4:
70 can be fit into 288 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 280 from 288 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 70

Let's proceed to step 5:
70 can be fit into 87 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 541.0
Deduct 70 from 87 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 70

Moving on to step 6:
70 can be fit into 171 2 times, resulting in a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 5412.0
Subtracting 140 from 171 leaves us with 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 7:
When dividing 310 by 70, we get 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 5412.4
If we take 280 away from 310, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 5412.44
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 5412.44 with a remaining 0.02.
