870341 divided by 70 
We want to divide 870341 by 70.

Going ahead to step 1:
70 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 70

Step 2:
The number 70 fits into 87 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 70 from 87 to get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 70

On to step 3:
The number 70 fits into 170 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 140 away from 170, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 70

Let's proceed to step 4:
70 goes into 303 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 280 from 303 leaves us with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 70

Going ahead to step 5:
If we divide 234 by 70, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 1243.0
Subtract 210 from 234 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 70

Moving on to step 6:
When dividing 241 by 70, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 12433.0
The remainder is 31 after subtracting 210 from 241.
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:
If we divide 310 by 70, we get 4 and a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 12433.4
Subtracting 280 from 310 leaves us 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.

Step 8:
When dividing 300 by 70, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 12433.44
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 12433.44 with a balance of 0.02.
