We look at the division of 401178 by 81 
We want to figure out the number of times 401178 can be divided by 81.

Going ahead to step 1:
When dividing 4 by 81, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 81

On 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.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 81

Advancing to step 3:
401 divided by 81 is 4 with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 77 after subtracting 324 from 401.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 81

Advancing to step 4:
The number 81 fits into 771 9 times, leaving a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 729 from 771 to get 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 81

On to step 5:
When dividing 427 by 81, we get 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
If we subtract 405 from 427, we get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 81

Going ahead to step 6:
228 divided by 81 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 4952.0
Subtracting 162 from 228 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
If we divide 660 by 81, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 4952.8
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 81, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 4952.81
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
81 can be fit into 390 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 4952.814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 10:
660 divided by 81 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4952.8148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 4952.81481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
When dividing 390 by 81, we get 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 4952.814814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
81 goes into 660 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 4952.8148148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
When dividing 120 by 81, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 4952.81481481
Deduct 81 from 120 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 4952.81481481 and a remainder of 3.9e-08.
