Let's divide 121781 by 55
Our goal is to divide 121781 by 55.

Going ahead to step 1:
55 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 55

Moving on to step 2:
55 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 55

Advancing to step 3:
55 can be fit into 121 2 times, resulting in a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 11 after subtracting 110 from 121.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 55

Step 4:
If we divide 117 by 55, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 110 from 117 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 55

On to step 5:
55 goes into 78 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 221.0
The remainder is 23 after subtracting 55 from 78.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 55

Let's proceed to step 6:
If we divide 231 by 55, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 2214.0
Subtract 220 from 231 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 55, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2214.2
Subtracting 110 from 110 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
55 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2214.2
Subtracting 0 from 0 leaves us with 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 9:
The number 55 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2214.2
Subtracting 0 from 0 leaves us with 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 2214.2, with a leftover of 0.0.
