307984 divided by 70 
Our goal is to divide 307984 by 70.

Step 1:
If we divide 3 by 70, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 70

Advancing to step 2:
If we divide 30 by 70, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 70

Going ahead to step 3:
70 can be fit into 307 4 times, resulting in a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 280 from 307 and we're left with 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 70

Advancing to step 4:
70 goes into 279 3 times with a remainder of 69.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 210 from 279 to get 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 70

Advancing to step 5:
70 goes into 698 9 times with a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 439.0
Subtracting 630 from 698 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 70

Let's proceed to step 6:
684 divided by 70 is 9 with a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 4399.0
If we take 630 away from 684, we end up 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.

Advancing to step 7:
70 goes into 540 7 times with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 4399.7
If we subtract 490 from 540, we 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.

Going ahead to step 8:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 4399.77
Subtract 490 from 500 to 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.

After the division, we end up with 4399.77 and a remainder of 0.01.
