27486557 divided by 20 
We want to divide 27486557 by 20.

Step 1:
20 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 20

Moving on to step 2:
The number 20 fits into 27 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 20 from 27 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

Going ahead to step 3:
When dividing 74 by 20, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 60 from 74, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 20

Advancing to step 4:
20 goes into 148 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 140 from 148 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

Step 5:
The number 20 fits into 86 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
Deduct 80 from 86 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 20

Let's proceed to step 6:
The number 20 fits into 65 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 13743.0
Subtract 60 from 65 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 20

Let's proceed to step 7:
When dividing 55 by 20, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 137432.0
If we subtract 40 from 55, we get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 20

On to step 8:
When dividing 157 by 20, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 1374327.0
If we subtract 140 from 157, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 1374327.8
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1374327.85
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1374327.85
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1374327.85
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1374327.85 with a balance of 0.0.
