We're dividing 27379262 by 643 
Let's see how many times 643 fits into 27379262.

Advancing to step 1:
When dividing 2 by 643, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 643

Step 2:
27 divided by 643 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 643

Moving on to step 3:
When dividing 273 by 643, we get 0 with a remainder of 273.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 273, we end up with 273.
Grab the next digit (7) from the dividend, add it to 273, then carry on: 2737 / 643

Moving on to step 4:
When dividing 2737 by 643, we get 4 with a remainder of 165.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2572 from 2737 leaves us with 165.
Append the next digit (9) from the dividend to 165 and continue with: 1659 / 643

Let's proceed to step 5:
643 can be fit into 1659 2 times, resulting in a remainder of 373.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 1286 from 1659 and we're left with 373.
Append the next digit (2) from the dividend to 373 and continue with: 3732 / 643

On to step 6:
3732 divided by 643 is 5 with a remainder of 517.
The next digit of our result is 5. 
Result so far: 425.0
The remainder is 517 after subtracting 3215 from 3732.
Fetch the next digit (6) from the dividend, attach it to 517 and continue: 5176 / 643

Going ahead to step 7:
If we divide 5176 by 643, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 4258.0
Subtract 5144 from 5176 to get 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 643

Let's proceed to step 8:
The number 643 fits into 322 0 times, leaving a remainder of 322.
Use 0 as the next digit of our solution. 
Result so far: 42580.0
Subtracting 0 from 322 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

On to step 9:
643 goes into 3220 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 42580.5
If we subtract 3215 from 3220, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 643, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 42580.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
643 can be fit into 500 0 times, resulting in a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 42580.5
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 42580.5 with a balance of 0.05.
