Let's divide 18866129 by 120
We want to figure out the number of times 18866129 can be divided by 120.

Advancing to step 1:
When dividing 1 by 120, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 120

Going ahead to step 2:
120 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 120

Advancing to step 3:
120 can be fit into 188 1 times, resulting in a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 120 from 188 to get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 120

Moving on to step 4:
686 divided by 120 is 5 with a remainder of 86.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 600 from 686, we get 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 120

Going ahead to step 5:
When dividing 866 by 120, we get 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
The remainder is 26 after subtracting 840 from 866.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 120

Moving on to step 6:
If we divide 261 by 120, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 1572.0
If we take 240 away from 261, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 120

Step 7:
The number 120 fits into 212 1 times, leaving a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 15721.0
If we take 120 away from 212, we end up with 92.
Take the next digit (9) from the dividend and append it to 92, then repeat: 929 / 120

Step 8:
If we divide 929 by 120, we get 7 and a remainder of 89.
The number 7 becomes the next digit in our result. 
Result so far: 157217.0
Deduct 840 from 929 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
120 can be fit into 890 7 times, resulting in a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 157217.7
Deduct 840 from 890 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
500 divided by 120 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 157217.74
Deduct 480 from 500 and we're left 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.

Advancing to step 11:
The number 120 fits into 200 1 times, leaving a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 157217.741
If we subtract 120 from 200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
When dividing 800 by 120, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 157217.7416
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
120 can be fit into 800 6 times, resulting in a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 157217.74166
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 157217.74166, and the remainder is 8e-05.
