We divide 42038110 by 120
We want to divide 42038110 by 120.

Step 1:
If we divide 4 by 120, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 120

Step 2:
If we divide 42 by 120, we get 0 and a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 120

Step 3:
If we divide 420 by 120, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 360 from 420 to get 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 120

Step 4:
When dividing 603 by 120, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 600 from 603, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 120

Advancing to step 5:
If we divide 38 by 120, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 350.0
If we subtract 0 from 38, we get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 120

Moving on to step 6:
The number 120 fits into 381 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3503.0
Subtracting 360 from 381 leaves us with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 120

Moving on to step 7:
120 goes into 211 1 times with a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 35031.0
If we subtract 120 from 211, we get 91.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 120

Advancing to step 8:
120 can be fit into 910 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 350317.0
Subtract 840 from 910 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
When dividing 700 by 120, we get 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 350317.5
Subtracting 600 from 700 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
If we divide 1000 by 120, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 350317.58
Deduct 960 from 1000 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.

Moving on to step 11:
120 goes into 400 3 times with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 350317.583
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
120 can be fit into 400 3 times, resulting in a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 350317.5833
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 350317.5833 and a remainder of 0.0004.
