We're dividing 18213342 by 121 
Our goal is to divide 18213342 by 121.

Step 1:
When dividing 1 by 121, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 121

Moving on to step 2:
18 divided by 121 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 121

Let's proceed to step 3:
If we divide 182 by 121, we get 1 and a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 121 from 182, we get 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 121

Moving on to step 4:
611 divided by 121 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 605 away from 611, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 121

On to step 5:
121 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 121

Going ahead to step 6:
When dividing 633 by 121, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 1505.0
The remainder is 28 after subtracting 605 from 633.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 121

Advancing to step 7:
284 divided by 121 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 15052.0
If we subtract 242 from 284, we get 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 121

Step 8:
121 can be fit into 422 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 150523.0
If we take 363 away from 422, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
When dividing 590 by 121, we get 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 150523.4
Deduct 484 from 590 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 10:
1060 divided by 121 is 8 with a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 150523.48
Subtract 968 from 1060 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
121 can be fit into 920 7 times, resulting in a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 150523.487
Subtract 847 from 920 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
If we divide 730 by 121, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 150523.4876
If we take 726 away from 730, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
121 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 150523.4876
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
121 can be fit into 400 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 150523.487603
The remainder is 37 after subtracting 363 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 15:
121 goes into 370 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 150523.4876033
Deduct 363 from 370 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 150523.4876033 and a remainder of 7e-08.
