We're dividing 16152024 by 121 
Let's see how many times 121 fits into 16152024.

On to step 1:
1 divided by 121 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 121

Let's proceed to step 2:
16 divided by 121 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 121

Let's proceed to step 3:
If we divide 161 by 121, we get 1 and a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 40 after subtracting 121 from 161.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 121

Moving on to step 4:
121 can be fit into 405 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 13.0
If we take 363 away from 405, we end up with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 121

Going ahead to step 5:
The number 121 fits into 422 3 times, leaving a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 363 from 422 and we're left with 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 121

Going ahead to step 6:
590 divided by 121 is 4 with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 1334.0
Deduct 484 from 590 and we're left with 106.
Take the next digit (2) from the dividend and append it to 106, then repeat: 1062 / 121

Moving on to step 7:
The number 121 fits into 1062 8 times, leaving a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 13348.0
The remainder is 94 after subtracting 968 from 1062.
Take the next digit (4) from the dividend and append it to 94, then repeat: 944 / 121

On to step 8:
When dividing 944 by 121, we get 7 with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 133487.0
If we subtract 847 from 944, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 9:
When dividing 970 by 121, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 133487.8
Subtracting 968 from 970 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
121 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 133487.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
121 can be fit into 200 1 times, resulting in a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 133487.801
If we take 121 away from 200, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
790 divided by 121 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 133487.8016
Subtract 726 from 790 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
121 can be fit into 640 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 133487.80165
Deduct 605 from 640 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 121, we get 2 with a remainder of 108.
The next digit of our result is 2. 
Result so far: 133487.801652
Subtract 242 from 350 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 15:
1080 divided by 121 is 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 133487.8016528
Subtracting 968 from 1080 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 16:
When dividing 1120 by 121, we get 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 133487.80165289
The remainder is 31 after subtracting 1089 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 133487.80165289, with a leftover of 3.1e-08.
