Let's divide 401578 by 27
We're looking to find how many times 27 goes into 401578.

Step 1:
27 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 27

On to step 2:
If we divide 40 by 27, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 27 from 40, we get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 27

Moving on to step 3:
27 can be fit into 131 4 times, resulting in a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 108 from 131, we get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 27

Moving on to step 4:
27 goes into 235 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 148.0
Subtracting 216 from 235 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 27

Let's proceed to step 5:
27 goes into 197 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 1487.0
Deduct 189 from 197 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 27

On to step 6:
The number 27 fits into 88 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 14873.0
If we take 81 away from 88, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
When dividing 70 by 27, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 14873.2
Subtract 54 from 70 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.

Going ahead to step 8:
27 can be fit into 160 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14873.25
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
27 goes into 250 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 14873.259
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
70 divided by 27 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 14873.2592
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
When dividing 160 by 27, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14873.25925
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
If we divide 250 by 27, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 14873.259259
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
70 divided by 27 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 14873.2592592
If we subtract 54 from 70, we 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.

Going ahead to step 14:
160 divided by 27 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14873.25925925
If we take 135 away from 160, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 14873.25925925 with a remaining 2.5e-08.
