We divide 649978 by 81
We want to divide 649978 by 81.

On to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the 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 / 81

Step 2:
If we divide 64 by 81, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 81

On to step 3:
If we divide 649 by 81, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 648 from 649 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 81

On to step 4:
When dividing 19 by 81, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtract 0 from 19 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 81

Advancing to step 5:
197 divided by 81 is 2 with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
Deduct 162 from 197 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 81

Let's proceed to step 6:
The number 81 fits into 358 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 8024.0
Deduct 324 from 358 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 81 fits into 340 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8024.4
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 81, we get 1 and a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 8024.41
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
81 goes into 790 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 8024.419
Deduct 729 from 790 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
610 divided by 81 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 8024.4197
Deduct 567 from 610 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
The number 81 fits into 430 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 8024.41975
The remainder is 25 after subtracting 405 from 430.
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 12:
The number 81 fits into 250 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 8024.419753
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
When dividing 70 by 81, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8024.419753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
81 goes into 700 8 times with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8024.41975308
Deduct 648 from 700 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.

In conclusion, the division gives 8024.41975308 with a balance of 5.2e-08.
