640481 ÷ 84 
Let's see how many times 84 fits into 640481.

Moving on to step 1:
When dividing 6 by 84, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 84

Let's proceed to step 2:
When dividing 64 by 84, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 84

Step 3:
640 divided by 84 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 588 from 640 leaves us with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 84

Advancing to step 4:
The number 84 fits into 524 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtracting 504 from 524 leaves us with 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 84

Let's proceed to step 5:
When dividing 208 by 84, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 762.0
If we subtract 168 from 208, we get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 84

On to step 6:
401 divided by 84 is 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 7624.0
Subtract 336 from 401 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
84 can be fit into 650 7 times, resulting in a remainder of 62.
The next digit of our result is 7. 
Result so far: 7624.7
Deduct 588 from 650 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
If we divide 620 by 84, we get 7 and a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7624.77
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 7624.77 with a balance of 0.032.
