391643 divided by 27 
We're looking to find how many times 27 goes into 391643.

Moving on to step 1:
27 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 27

Going ahead to step 2:
27 goes into 39 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 27 from 39 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 27

Moving on to step 3:
When dividing 121 by 27, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 108 from 121 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 27

Let's proceed to step 4:
27 goes into 136 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Deduct 135 from 136 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 27

Let's proceed to step 5:
The number 27 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 1450.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 27

Advancing to step 6:
If we divide 143 by 27, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 14505.0
The remainder is 8 after subtracting 135 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 27 is 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 14505.2
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
The number 27 fits into 260 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 14505.29
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 27, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 14505.296
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
27 can be fit into 80 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 14505.2962
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
27 can be fit into 260 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 14505.29629
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
If we divide 170 by 27, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 14505.296296
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
27 can be fit into 80 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 14505.2962962
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
27 can be fit into 260 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 14505.29629629
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 14505.29629629 with a remainder of 1.7e-08.
