We look at the division of 507049 by 70 
We want to figure out the number of times 507049 can be divided by 70.

Going ahead to step 1:
If we divide 5 by 70, we get 0 and 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.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 70

Advancing to step 2:
When dividing 50 by 70, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 70

Going ahead to step 3:
507 divided by 70 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 490 away from 507, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 70

Advancing to step 4:
170 divided by 70 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 140 from 170, we get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 70

Moving on to step 5:
70 can be fit into 304 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 724.0
If we take 280 away from 304, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 70

Moving on to step 6:
If we divide 249 by 70, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 7243.0
Subtract 210 from 249 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
If we divide 390 by 70, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 7243.5
Subtract 350 from 390 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.

Going ahead to step 8:
If we divide 400 by 70, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7243.55
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.

The final result is 7243.55 with a remainder of 0.05.
