277640 divided by 20 
We're looking to find how many times 20 goes into 277640.

Moving on to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 20

Step 2:
27 divided by 20 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 20 from 27 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 20

Advancing to step 3:
20 can be fit into 77 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 60 from 77 leaves us with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 20

Going ahead to step 4:
If we divide 176 by 20, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 138.0
Deduct 160 from 176 and we're left with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 20

Step 5:
20 goes into 164 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1388.0
The remainder is 4 after subtracting 160 from 164.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Let's proceed to step 6:
20 can be fit into 40 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 13882.0
Subtract 40 from 40 to 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.

On to step 7:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13882.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13882.0
Subtract 0 from 0 to 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.

The final outcome is 13882.0, with a leftover of 0.0.
