520261 ÷ 75 
We want to figure out the number of times 520261 can be divided by 75.

Moving on to step 1:
75 can be fit into 5 0 times, resulting in 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 75

Let's proceed to step 2:
If we divide 52 by 75, we get 0 and a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 75

Going ahead to step 3:
If we divide 520 by 75, we get 6 and a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 450 away from 520, we end up with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 75

On to step 4:
When dividing 702 by 75, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 675 from 702 to get 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 75

Let's proceed to step 5:
The number 75 fits into 276 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 693.0
Subtracting 225 from 276 leaves us with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 75

On to step 6:
When dividing 511 by 75, we get 6 with a remainder of 61.
Write down 6 as next digit of the result. 
Result so far: 6936.0
If we subtract 450 from 511, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
75 goes into 610 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 6936.8
If we subtract 600 from 610, 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.

Let's proceed to step 8:
The number 75 fits into 100 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 6936.81
If we subtract 75 from 100, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 75 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 6936.813
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
250 divided by 75 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 6936.8133
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 6936.8133 with a remaining 0.00025.
