We look at the division of 512025 by 70 
Let's see how many times 70 fits into 512025.

Step 1:
70 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 70

On to step 2:
51 divided by 70 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 70

Moving on to step 3:
70 can be fit into 512 7 times, resulting in a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 490 from 512 to get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 70

Let's proceed to step 4:
70 goes into 220 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
Subtracting 210 from 220 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 70

Advancing to step 5:
When dividing 102 by 70, we get 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
If we subtract 70 from 102, we get 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 70

Let's proceed to step 6:
70 goes into 325 4 times with a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 7314.0
Subtracting 280 from 325 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
450 divided by 70 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 7314.6
If we take 420 away from 450, we end up 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.

Let's proceed to step 8:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 7314.64
Subtract 280 from 300 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.

Let's proceed to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 7314.642
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.

Moving on to step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 7314.6428
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 11:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 7314.64285
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.

Going ahead to step 12:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 7314.642857
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.

Going ahead to step 13:
When dividing 100 by 70, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 7314.6428571
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.

On to step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 7314.64285714
Subtract 280 from 300 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.

After the division, we end up with 7314.64285714 and a remainder of 2e-08.
