Let's divide 20811517 by 55
We want to figure out the number of times 20811517 can be divided by 55.

Moving on to step 1:
When dividing 2 by 55, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 55

Moving on to step 2:
55 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 55

Let's proceed to step 3:
55 can be fit into 208 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 165 from 208 and we're left with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 55

Moving on to step 4:
55 goes into 431 7 times with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 385 from 431, we get 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 55

Moving on to step 5:
When dividing 461 by 55, we get 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 378.0
Deduct 440 from 461 and we're left with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 55

Advancing to step 6:
When dividing 215 by 55, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 3783.0
If we subtract 165 from 215, we get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 55

Step 7:
The number 55 fits into 501 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 37839.0
Subtract 495 from 501 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 55

Step 8:
When dividing 67 by 55, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 378391.0
If we subtract 55 from 67, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 55 fits into 120 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 378391.2
Deduct 110 from 120 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 378391.21
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
55 goes into 450 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 378391.218
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 378391.2181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
55 can be fit into 450 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 378391.21818
Deduct 440 from 450 and we're left with 10.
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 14:
When dividing 100 by 55, we get 1 with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 378391.218181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
450 divided by 55 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 378391.2181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 16:
100 divided by 55 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 378391.21818181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 378391.21818181, and the remainder is 4.5e-08.
