We're dividing 259408 by 70 
We want to divide 259408 by 70.

Step 1:
70 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 70

Advancing to step 2:
The number 70 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 70

Going ahead to step 3:
70 can be fit into 259 3 times, resulting in a remainder of 49.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 210 from 259, we get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 70

Moving on to step 4:
494 divided by 70 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 490 from 494 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 70

Step 5:
The number 70 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 370.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 70

Step 6:
70 goes into 408 5 times with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 3705.0
Subtracting 350 from 408 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 7:
When dividing 580 by 70, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3705.8
Subtract 560 from 580 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.

Moving on to step 8:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 3705.82
Subtracting 140 from 200 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.

Going ahead to step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 3705.828
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.

Moving on to step 10:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 3705.8285
The remainder is 50 after subtracting 350 from 400.
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 11:
70 goes into 500 7 times with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 3705.82857
Subtracting 490 from 500 leaves us 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.

On to step 12:
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: 3705.828571
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.

Step 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 3705.8285714
If we subtract 280 from 300, we 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.

Going ahead to step 14:
200 divided by 70 is 2 with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 3705.82857142
Deduct 140 from 200 and we're left 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.

In conclusion, the division gives 3705.82857142 with a balance of 6e-08.
