18620306 divided by 121 
Our goal is to divide 18620306 by 121.

On to step 1:
If we divide 1 by 121, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 121

Moving on to step 2:
121 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 121

Step 3:
The number 121 fits into 186 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 121 from 186 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 121

On to step 4:
121 goes into 652 5 times with a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 605 from 652, we get 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 121

Step 5:
121 goes into 470 3 times with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
Subtract 363 from 470 to get 107.
Take the next digit (3) from the dividend and append it to 107, then repeat: 1073 / 121

Let's proceed to step 6:
121 goes into 1073 8 times with a remainder of 105.
Use 8 as the next digit of our solution. 
Result so far: 1538.0
Subtracting 968 from 1073 leaves us with 105.
Grab the next digit (0) from the dividend, add it to 105, then carry on: 1050 / 121

Step 7:
1050 divided by 121 is 8 with a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 15388.0
Subtract 968 from 1050 to get 82.
Grab the next digit (6) from the dividend, add it to 82, then carry on: 826 / 121

On to step 8:
121 goes into 826 6 times with a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 153886.0
Subtract 726 from 826 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
If we divide 1000 by 121, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 153886.8
If we subtract 968 from 1000, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
121 can be fit into 320 2 times, resulting in a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 153886.82
If we subtract 242 from 320, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
If we divide 780 by 121, we get 6 and a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 153886.826
If we subtract 726 from 780, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
If we divide 540 by 121, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 153886.8264
If we subtract 484 from 540, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
560 divided by 121 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 153886.82644
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.

In conclusion, the division gives 153886.82644 with a balance of 7.6e-05.
