764521 ÷ 3 
Our goal is to divide 764521 by 3.

Moving on to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Going ahead to step 2:
If we divide 16 by 3, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 15 away from 16, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 3

Moving on to step 3:
3 goes into 14 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 254.0
The remainder is 2 after subtracting 12 from 14.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Going ahead to step 4:
When dividing 25 by 3, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2548.0
If we subtract 24 from 25, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Moving on to step 5:
3 goes into 12 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 25484.0
The remainder is 0 after subtracting 12 from 12.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Advancing to step 6:
1 divided by 3 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 254840.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 254840.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 254840.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 254840.33, with a leftover of 0.001.
