We look at the division of 279257 by 70 
Our goal is to divide 279257 by 70.

Advancing to step 1:
2 divided by 70 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 70

Advancing to step 2:
If we divide 27 by 70, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 70

Advancing to step 3:
70 can be fit into 279 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 210 from 279 leaves us with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 70

Step 4:
70 goes into 692 9 times with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we take 630 away from 692, we end up with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 70

Step 5:
70 can be fit into 625 8 times, resulting in a remainder of 65.
The next digit of our result is 8. 
Result so far: 398.0
Subtract 560 from 625 to get 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 70

Advancing to step 6:
The number 70 fits into 657 9 times, leaving a remainder of 27.
The next digit of our result is 9. 
Result so far: 3989.0
The remainder is 27 after subtracting 630 from 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
70 can be fit into 270 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3989.3
Subtracting 210 from 270 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 70 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3989.38
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
When dividing 400 by 70, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3989.385
If we take 350 away from 400, we end up 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.

Let's proceed to step 10:
When dividing 500 by 70, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3989.3857
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 3989.38571
If we subtract 70 from 100, we 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.

Advancing to step 12:
If we divide 300 by 70, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3989.385714
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.

Let's proceed to step 13:
70 goes into 200 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 3989.3857142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
70 goes into 600 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3989.38571428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 3989.38571428 with a remainder of 4e-08.
