We look at the division of 27639459 by 393 
We want to figure out the number of times 27639459 can be divided by 393.

Moving on to step 1:
393 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 393

Moving on to step 2:
If we divide 27 by 393, we get 0 and a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 393

Moving on to step 3:
When dividing 276 by 393, we get 0 with a remainder of 276.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 276 and we're left with 276.
Take the next digit (3) from the dividend and append it to 276, then repeat: 2763 / 393

Advancing to step 4:
If we divide 2763 by 393, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 12 after subtracting 2751 from 2763.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 393

Moving on to step 5:
393 can be fit into 129 0 times, resulting in a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 129, we get 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 393

On to step 6:
393 goes into 1294 3 times with a remainder of 115.
Record the quotient 3 as the next digit in the result. 
Result so far: 703.0
Subtract 1179 from 1294 to get 115.
Grab the next digit (5) from the dividend, add it to 115, then carry on: 1155 / 393

Let's proceed to step 7:
1155 divided by 393 is 2 with a remainder of 369.
Use 2 as the next digit of our solution. 
Result so far: 7032.0
If we take 786 away from 1155, we end up with 369.
Grab the next digit (9) from the dividend, add it to 369, then carry on: 3699 / 393

Step 8:
393 can be fit into 3699 9 times, resulting in a remainder of 162.
Put 9 as the next digit of the answer. 
Result so far: 70329.0
If we take 3537 away from 3699, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 9:
393 goes into 1620 4 times with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 70329.4
Subtract 1572 from 1620 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
393 goes into 480 1 times with a remainder of 87.
The next digit of our result is 1. 
Result so far: 70329.41
The remainder is 87 after subtracting 393 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 11:
When dividing 870 by 393, we get 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 70329.412
Subtracting 786 from 870 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
393 can be fit into 840 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 70329.4122
The remainder is 54 after subtracting 786 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 70329.4122 with a remainder of 0.00054.
