We look at the division of 21820710 by 121 
Let's see how many times 121 fits into 21820710.

Step 1:
121 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 121

On to step 2:
If we divide 21 by 121, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 121

Moving on to step 3:
121 can be fit into 218 1 times, resulting in a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 121 from 218 leaves us with 97.
Take the next digit (2) from the dividend and append it to 97, then repeat: 972 / 121

Advancing to step 4:
When dividing 972 by 121, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 4 after subtracting 968 from 972.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 121

Moving on to step 5:
121 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we take 0 away from 40, we end up with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 121

Step 6:
The number 121 fits into 407 3 times, leaving a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 1803.0
The remainder is 44 after subtracting 363 from 407.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 121

Let's proceed to step 7:
441 divided by 121 is 3 with a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 18033.0
The remainder is 78 after subtracting 363 from 441.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 121

On to step 8:
121 can be fit into 780 6 times, resulting in a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 180336.0
If we take 726 away from 780, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
The number 121 fits into 540 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 180336.4
Subtracting 484 from 540 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
121 can be fit into 560 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 180336.44
Subtracting 484 from 560 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 180336.44, and the remainder is 0.076.
