We look at the division of 869944 by 70 
We're looking to find how many times 70 goes into 869944.

Step 1:
When dividing 8 by 70, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 70

Step 2:
70 can be fit into 86 1 times, resulting in a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 70 from 86.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 70

On to step 3:
169 divided by 70 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 140 from 169, we get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 70

Step 4:
70 goes into 299 4 times with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 280 from 299 and we're left with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 70

Going ahead to step 5:
70 goes into 194 2 times with a remainder of 54.
The next digit of our result is 2. 
Result so far: 1242.0
The remainder is 54 after subtracting 140 from 194.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 70

Going ahead to step 6:
70 can be fit into 544 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 12427.0
Deduct 490 from 544 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
70 goes into 540 7 times with a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 12427.7
Deduct 490 from 540 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 12427.77
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 12427.77 with a remainder of 0.01.
