We look at the division of 23971828 by 120 
We want to divide 23971828 by 120.

Going ahead to step 1:
When dividing 2 by 120, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 120

On to step 2:
23 divided by 120 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 120

On to step 3:
When dividing 239 by 120, we get 1 with a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 120 away from 239, we end up with 119.
Append the next digit (7) from the dividend to 119 and continue with: 1197 / 120

Let's proceed to step 4:
The number 120 fits into 1197 9 times, leaving a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 117 after subtracting 1080 from 1197.
Take the next digit (1) from the dividend and append it to 117, then repeat: 1171 / 120

Going ahead to step 5:
120 can be fit into 1171 9 times, resulting in a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 199.0
If we subtract 1080 from 1171, we get 91.
Append the next digit (8) from the dividend to 91 and continue with: 918 / 120

Let's proceed to step 6:
120 goes into 918 7 times with a remainder of 78.
The next digit of our result is 7. 
Result so far: 1997.0
Subtract 840 from 918 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 120

Step 7:
The number 120 fits into 782 6 times, leaving a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 19976.0
Subtracting 720 from 782 leaves us with 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 120

Moving on to step 8:
When dividing 628 by 120, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 199765.0
If we subtract 600 from 628, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 120, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 199765.2
Subtracting 240 from 280 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
120 can be fit into 400 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 199765.23
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 120, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 199765.233
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 199765.233 with a remainder of 0.004.
