We're dividing 3505 by 70 
Our goal is to divide 3505 by 70.

Let's proceed to step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 70

Advancing to step 2:
If we divide 35 by 70, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 70

Going ahead to step 3:
350 divided by 70 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 350 from 350, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 70

Going ahead to step 4:
If we divide 5 by 70, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 5, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 5:
The number 70 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 50.0
Subtract 0 from 50 to get 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 6:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 50.07
Deduct 490 from 500 and we're left 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.

Moving on to step 7:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 50.071
Subtracting 70 from 100 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.

Moving on to step 8:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 50.0714
Subtracting 280 from 300 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
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: 50.07142
If we take 140 away from 200, we end up 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.

Let's proceed to step 10:
600 divided by 70 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 50.071428
Subtract 560 from 600 to get 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 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 50.0714285
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.

Moving on to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 50.07142857
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.

The final result is 50.07142857 with a remainder of 1e-08.
