84501631 divided by 486 
Let's see how many times 486 fits into 84501631.

On to step 1:
The number 486 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 486

Moving on to step 2:
The number 486 fits into 84 0 times, leaving a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 486

Step 3:
The number 486 fits into 845 1 times, leaving a remainder of 359.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 486 from 845 and we're left with 359.
Append the next digit (0) from the dividend to 359 and continue with: 3590 / 486

Moving on to step 4:
The number 486 fits into 3590 7 times, leaving a remainder of 188.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3402 from 3590 to get 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 486

Moving on to step 5:
The number 486 fits into 1881 3 times, leaving a remainder of 423.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtract 1458 from 1881 to get 423.
Include the next digit (6) from the dividend after 423, then repeat: 4236 / 486

Let's proceed to step 6:
The number 486 fits into 4236 8 times, leaving a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 1738.0
Subtracting 3888 from 4236 leaves us with 348.
Append the next digit (3) from the dividend to 348 and continue with: 3483 / 486

Step 7:
When dividing 3483 by 486, we get 7 with a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 17387.0
Deduct 3402 from 3483 and we're left with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 486

Let's proceed to step 8:
486 goes into 811 1 times with a remainder of 325.
Record the quotient 1 as the next digit in the result. 
Result so far: 173871.0
Subtracting 486 from 811 leaves us with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Going ahead to step 9:
486 can be fit into 3250 6 times, resulting in a remainder of 334.
Record the quotient 6 as the next digit in the result. 
Result so far: 173871.6
Subtracting 2916 from 3250 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
When dividing 3340 by 486, we get 6 with a remainder of 424.
Use 6 as the next digit of our solution. 
Result so far: 173871.66
Subtract 2916 from 3340 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

In conclusion, the division gives 173871.66 with a balance of 0.424.
