121540 ÷ 55 
Let's see how many times 55 fits into 121540.

Let's proceed to step 1:
55 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 55

On to step 2:
The number 55 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 55

Moving on to step 3:
If we divide 121 by 55, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we take 110 away from 121, we end up with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 55

Advancing to step 4:
The number 55 fits into 115 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 110 from 115 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 55

Going ahead to step 5:
When dividing 54 by 55, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
Subtract 0 from 54 to get 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 55

Let's proceed to step 6:
When dividing 540 by 55, we get 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 2209.0
If we subtract 495 from 540, 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.

Step 7:
When dividing 450 by 55, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 2209.8
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 8:
The number 55 fits into 100 1 times, leaving a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 2209.81
Subtracting 55 from 100 leaves us 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.

Step 9:
55 goes into 450 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 2209.818
The remainder is 10 after subtracting 440 from 450.
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:
100 divided by 55 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 2209.8181
Subtract 55 from 100 to 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.

On to step 11:
If we divide 450 by 55, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 2209.81818
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.

Moving on to step 12:
100 divided by 55 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 2209.818181
Subtracting 55 from 100 leaves us 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.

On to step 13:
When dividing 450 by 55, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 2209.8181818
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 14:
When dividing 100 by 55, we get 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 2209.81818181
Subtracting 55 from 100 leaves us 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 final result is 2209.81818181 with a remainder of 4.5e-08.
