We're dividing 405973 by 27 
We're looking to find how many times 27 goes into 405973.

Step 1:
The number 27 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 27

On to step 2:
The number 27 fits into 40 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 27 from 40.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 27

Step 3:
When dividing 135 by 27, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 135 from 135 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 27

Moving on to step 4:
27 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 150.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 27

Moving on to step 5:
27 goes into 97 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 1503.0
Deduct 81 from 97 and we're left with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 27

Let's proceed to step 6:
The number 27 fits into 163 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 15036.0
Subtracting 162 from 163 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 27 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15036.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 27 fits into 100 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 15036.03
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
When dividing 190 by 27, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 15036.037
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
27 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 15036.037
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
27 goes into 100 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 15036.03703
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
When dividing 190 by 27, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 15036.037037
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
If we divide 10 by 27, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15036.037037
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 27, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 15036.03703703
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 15036.03703703, with a leftover of 1.9e-08.
