We're dividing 638273 by 27 
We want to figure out the number of times 638273 can be divided by 27.

Moving on to step 1:
If we divide 6 by 27, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 27

Advancing to step 2:
If we divide 63 by 27, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 54 from 63 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 27

Moving on to step 3:
If we divide 98 by 27, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 81 from 98 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 27

Moving on to step 4:
27 can be fit into 172 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 236.0
If we take 162 away from 172, we end up with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 27

Moving on to step 5:
27 goes into 107 3 times with a remainder of 26.
The next digit of our result is 3. 
Result so far: 2363.0
The remainder is 26 after subtracting 81 from 107.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 27

Advancing to step 6:
The number 27 fits into 263 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 23639.0
The remainder is 20 after subtracting 243 from 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 27, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 23639.7
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
27 goes into 110 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 23639.74
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 27 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 23639.74
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
27 goes into 200 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 23639.7407
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 27, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 23639.74074
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
27 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 23639.74074
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
200 divided by 27 is 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 23639.7407407
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
110 divided by 27 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 23639.74074074
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 23639.74074074 with a balance of 2e-09.
