400918 divided by 81 
Let's see how many times 81 fits into 400918.

On to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 81

Advancing to step 2:
When dividing 40 by 81, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 81

On to step 3:
81 goes into 400 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 76 after subtracting 324 from 400.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 81

Going ahead to step 4:
When dividing 769 by 81, we get 9 with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 40 after subtracting 729 from 769.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 81

Advancing to step 5:
The number 81 fits into 401 4 times, leaving a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 494.0
If we take 324 away from 401, we end up with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 81

Going ahead to step 6:
The number 81 fits into 778 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 4949.0
Subtracting 729 from 778 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 81 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4949.6
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 81 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4949.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 81, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4949.604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
81 goes into 760 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 4949.6049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 4949.60493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 12:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 4949.604938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
81 can be fit into 220 2 times, resulting in a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4949.6049382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 14:
When dividing 580 by 81, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 4949.60493827
Subtracting 567 from 580 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 4949.60493827, with a leftover of 1.3e-08.
