We divide 401181 by 81
We want to figure out the number of times 401181 can be divided by 81.

On to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 81

Let's proceed to step 2:
40 divided by 81 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 81

Step 3:
If we divide 401 by 81, we get 4 and a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 324 away from 401, we end up with 77.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 81

Going ahead to step 4:
When dividing 771 by 81, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 729 from 771, we get 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 81

Advancing to step 5:
81 can be fit into 428 5 times, resulting in a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
If we subtract 405 from 428, we get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 81

On to step 6:
81 goes into 231 2 times with a remainder of 69.
The next digit of our result is 2. 
Result so far: 4952.0
If we subtract 162 from 231, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
81 goes into 690 8 times with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 4952.8
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4952.85
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
81 goes into 150 1 times with a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 4952.851
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
If we divide 690 by 81, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 4952.8518
If we subtract 648 from 690, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
81 goes into 420 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4952.85185
If we subtract 405 from 420, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
81 goes into 150 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 4952.851851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
81 can be fit into 690 8 times, resulting in a remainder of 42.
The next digit of our result is 8. 
Result so far: 4952.8518518
Deduct 648 from 690 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 14:
81 goes into 420 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4952.85185185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 4952.85185185 with a remainder of 1.5e-08.
