We look at the division of 16558176 by 121 
Let's see how many times 121 fits into 16558176.

Moving on to step 1:
121 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 121

Advancing to step 2:
121 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 121

Let's proceed to step 3:
When dividing 165 by 121, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 121 away from 165, we end up with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 121

Moving on to step 4:
If we divide 445 by 121, we get 3 and a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 363 from 445, we get 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 121

Step 5:
The number 121 fits into 828 6 times, leaving a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we take 726 away from 828, we end up with 102.
Grab the next digit (1) from the dividend, add it to 102, then carry on: 1021 / 121

Moving on to step 6:
When dividing 1021 by 121, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 1368.0
Subtract 968 from 1021 to get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 121

Moving on to step 7:
The number 121 fits into 537 4 times, leaving a remainder of 53.
The next digit of our result is 4. 
Result so far: 13684.0
Deduct 484 from 537 and we're left with 53.
Grab the next digit (6) from the dividend, add it to 53, then carry on: 536 / 121

Going ahead to step 8:
When dividing 536 by 121, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 136844.0
If we subtract 484 from 536, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 121 fits into 520 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 136844.4
The remainder is 36 after subtracting 484 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 121 fits into 360 2 times, leaving a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 136844.42
Subtract 242 from 360 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 11:
The number 121 fits into 1180 9 times, leaving a remainder of 91.
Write down 9 as next digit of the result. 
Result so far: 136844.429
If we take 1089 away from 1180, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 12:
The number 121 fits into 910 7 times, leaving a remainder of 63.
The next digit of our result is 7. 
Result so far: 136844.4297
If we subtract 847 from 910, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 13:
The number 121 fits into 630 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 136844.42975
Subtracting 605 from 630 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
When dividing 250 by 121, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 136844.429752
The remainder is 8 after subtracting 242 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
When dividing 80 by 121, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 136844.429752
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
The number 121 fits into 800 6 times, leaving a remainder of 74.
The next digit of our result is 6. 
Result so far: 136844.42975206
Subtracting 726 from 800 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 136844.42975206, with a leftover of 7.4e-08.
