520304 ÷ 70 
Our goal is to divide 520304 by 70.

Step 1:
The number 70 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 70

Going ahead to step 2:
70 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 70

On to step 3:
When dividing 520 by 70, we get 7 with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 30 after subtracting 490 from 520.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 70

Advancing to step 4:
70 can be fit into 303 4 times, resulting in a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 23 after subtracting 280 from 303.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 70

Going ahead to step 5:
70 goes into 230 3 times with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Deduct 210 from 230 and we're left with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 70

On to step 6:
70 can be fit into 204 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 7432.0
Subtract 140 from 204 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
70 goes into 640 9 times with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 7432.9
If we subtract 630 from 640, 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.

Step 8:
When dividing 100 by 70, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7432.91
The remainder is 30 after subtracting 70 from 100.
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 9:
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: 7432.914
Deduct 280 from 300 and we're left 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.

Advancing to step 10:
If we divide 200 by 70, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 7432.9142
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.

On to step 11:
When dividing 600 by 70, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 7432.91428
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.

On to step 12:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 7432.914285
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 13:
When dividing 500 by 70, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7432.9142857
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.

Going ahead to step 14:
When dividing 100 by 70, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 7432.91428571
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.

After the division, we end up with 7432.91428571 and a remainder of 3e-08.
