Let's divide 507240 by 70
We want to figure out the number of times 507240 can be divided by 70.

Going ahead to step 1:
The number 70 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 70

Going ahead to step 2:
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: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 70

Step 3:
70 can be fit into 507 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 490 from 507 leaves us with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 70

Going ahead to step 4:
70 can be fit into 172 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 140 from 172 and we're left with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 70

Advancing to step 5:
70 can be fit into 324 4 times, resulting in a remainder of 44.
The next digit of our result is 4. 
Result so far: 724.0
Subtract 280 from 324 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 70

Advancing to step 6:
70 goes into 440 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7246.0
If we take 420 away from 440, we end up 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 7:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 7246.2
Subtract 140 from 200 to get 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 8:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 7246.28
Deduct 560 from 600 and we're left 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.

Step 9:
70 can be fit into 400 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7246.285
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 10:
500 divided by 70 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 7246.2857
If we subtract 490 from 500, 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.

Going ahead to step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 7246.28571
If we take 70 away from 100, 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.

Going ahead to step 12:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 7246.285714
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.

Step 13:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 7246.2857142
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 14:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 7246.28571428
Subtracting 560 from 600 leaves us 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.

The final outcome is 7246.28571428, with a leftover of 4e-08.
