431401 ÷ 27 
We want to divide 431401 by 27.

Let's proceed to step 1:
If we divide 4 by 27, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 27

Going ahead to step 2:
The number 27 fits into 43 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 27 from 43 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 27

Going ahead to step 3:
27 can be fit into 161 5 times, resulting in a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 26 after subtracting 135 from 161.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 27

On to step 4:
27 can be fit into 264 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we subtract 243 from 264, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 27

Going ahead to step 5:
When dividing 210 by 27, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 1597.0
Subtract 189 from 210 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 27

Moving on to step 6:
If we divide 211 by 27, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 15977.0
Subtracting 189 from 211 leaves us 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.

Step 7:
The number 27 fits into 220 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 15977.8
If we subtract 216 from 220, we 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.

Advancing to step 8:
27 goes into 40 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 15977.81
Deduct 27 from 40 and we're left 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.

Advancing to step 9:
If we divide 130 by 27, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 15977.814
Deduct 108 from 130 and we're left 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.

Step 10:
220 divided by 27 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15977.8148
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
When dividing 40 by 27, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 15977.81481
Deduct 27 from 40 and we're left 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.

Moving on to step 12:
27 can be fit into 130 4 times, resulting in a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 15977.814814
If we take 108 away from 130, 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.

Step 13:
27 goes into 220 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 15977.8148148
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 27 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 15977.81481481
Subtracting 27 from 40 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 result is 15977.81481481 with a remainder of 1.3e-08.
