521491 ÷ 67 
We want to divide 521491 by 67.

Step 1:
The number 67 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
If we subtract 0 from 5, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 67

Advancing to step 2:
67 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 67

Advancing to step 3:
67 goes into 521 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 469 from 521 and we're left with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 67

Step 4:
When dividing 524 by 67, we get 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 469 from 524 to get 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 67

Moving on to step 5:
When dividing 559 by 67, we get 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 778.0
Subtracting 536 from 559 leaves us with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 67

Going ahead to step 6:
The number 67 fits into 231 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 7783.0
If we subtract 201 from 231, we get 30.
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 7:
If we divide 300 by 67, we get 4 and a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7783.4
Subtracting 268 from 300 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
If we divide 320 by 67, we get 4 and a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 7783.44
Deduct 268 from 320 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 7783.44 with a remainder of 0.052.
