We look at the division of 20655594 by 687 
Let's see how many times 687 fits into 20655594.

Advancing to step 1:
The number 687 fits into 2 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 687

Going ahead to step 2:
687 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 687

Going ahead to step 3:
687 goes into 206 0 times with a remainder of 206.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 206, we get 206.
Grab the next digit (5) from the dividend, add it to 206, then carry on: 2065 / 687

Step 4:
687 can be fit into 2065 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2061 from 2065, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 687

Going ahead to step 5:
687 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 687

Let's proceed to step 6:
When dividing 455 by 687, we get 0 with a remainder of 455.
The next digit of our result is 0. 
Result so far: 300.0
If we subtract 0 from 455, we get 455.
Append the next digit (9) from the dividend to 455 and continue with: 4559 / 687

Moving on to step 7:
687 goes into 4559 6 times with a remainder of 437.
The next digit of our result is 6. 
Result so far: 3006.0
Deduct 4122 from 4559 and we're left with 437.
Bring next digit (4) of the dividend behind the 437 and repeat the process: 4374 / 687

Step 8:
When dividing 4374 by 687, we get 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 30066.0
Subtracting 4122 from 4374 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 9:
If we divide 2520 by 687, we get 3 and a remainder of 459.
Put 3 as the next digit of the answer. 
Result so far: 30066.3
Subtracting 2061 from 2520 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 10:
The number 687 fits into 4590 6 times, leaving a remainder of 468.
The next digit of our result is 6. 
Result so far: 30066.36
If we subtract 4122 from 4590, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 11:
4680 divided by 687 is 6 with a remainder of 558.
The next digit of our result is 6. 
Result so far: 30066.366
Subtracting 4122 from 4680 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The final outcome is 30066.366, with a leftover of 0.0558.
