121800 divided by 55 
Let's see how many times 55 fits into 121800.

Advancing to step 1:
If we divide 1 by 55, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 55

Let's proceed to step 2:
55 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 55

Let's proceed to step 3:
55 goes into 121 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 110 from 121, we get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 55

Moving on to step 4:
55 goes into 118 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 110 from 118 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 55

Moving on to step 5:
The number 55 fits into 80 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 221.0
The remainder is 25 after subtracting 55 from 80.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 55

Let's proceed to step 6:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 2214.0
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
300 divided by 55 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2214.5
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
The number 55 fits into 250 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 2214.54
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 55 fits into 300 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2214.545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
The number 55 fits into 250 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 2214.5454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 55, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2214.54545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
55 goes into 250 4 times with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 2214.545454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
55 goes into 300 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2214.5454545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 2214.54545454
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2214.54545454, and the remainder is 3e-08.
