Let's divide 644858 by 27
Our goal is to divide 644858 by 27.

Step 1:
27 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 27

Going ahead to step 2:
If we divide 64 by 27, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 54 from 64 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 27

Going ahead to step 3:
When dividing 104 by 27, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 81 from 104 leaves us with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 27

On to step 4:
238 divided by 27 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Deduct 216 from 238 and we're left with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 27

Step 5:
27 goes into 225 8 times with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 2388.0
Subtracting 216 from 225 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 27

Advancing to step 6:
When dividing 98 by 27, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 23883.0
Deduct 81 from 98 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 27, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 23883.6
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.

Going ahead to step 8:
When dividing 80 by 27, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 23883.62
If we subtract 54 from 80, we 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.

Let's proceed to step 9:
When dividing 260 by 27, we get 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 23883.629
Subtracting 243 from 260 leaves us with 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 10:
The number 27 fits into 170 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 23883.6296
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
The number 27 fits into 80 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 23883.62962
Subtracting 54 from 80 leaves us 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.

Advancing to step 12:
260 divided by 27 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 23883.629629
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.

Step 13:
170 divided by 27 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 23883.6296296
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.

Advancing to step 14:
27 goes into 80 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 23883.62962962
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.

In conclusion, the division gives 23883.62962962 with a balance of 2.6e-08.
