We're dividing 644251 by 27 
We want to figure out the number of times 644251 can be divided by 27.

Advancing to step 1:
27 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 27

Step 2:
The number 27 fits into 64 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 54 from 64 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 27

Moving on to step 3:
If we divide 104 by 27, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 81 away from 104, we end up with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 27

On to step 4:
When dividing 232 by 27, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 238.0
Subtracting 216 from 232 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 27

Advancing to step 5:
If we divide 165 by 27, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 2386.0
If we take 162 away from 165, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 27

On to step 6:
27 goes into 31 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 23861.0
If we take 27 away from 31, we end up 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.

Advancing to step 7:
40 divided by 27 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 23861.1
The remainder is 13 after subtracting 27 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
When dividing 130 by 27, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 23861.14
Subtract 108 from 130 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 27, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 23861.148
Subtract 216 from 220 to 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.

Let's proceed to step 10:
When dividing 40 by 27, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 23861.1481
If we take 27 away from 40, we end up 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 11:
The number 27 fits into 130 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 23861.14814
Subtract 108 from 130 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 27, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 23861.148148
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 13:
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: 23861.1481481
If we take 27 away from 40, we end up 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.

Let's proceed to step 14:
27 can be fit into 130 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 23861.14814814
If we subtract 108 from 130, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 23861.14814814 and a remainder of 2.2e-08.
