We divide 128374 by 42
Let's see how many times 42 fits into 128374.

Going ahead to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 42

Advancing to step 2:
If we divide 12 by 42, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 42

Advancing to step 3:
When dividing 128 by 42, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 126 from 128 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

Moving on to step 4:
If we divide 23 by 42, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 42

Advancing to step 5:
237 divided by 42 is 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 305.0
Subtracting 210 from 237 leaves us with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 42

Step 6:
If we divide 274 by 42, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 3056.0
Subtract 252 from 274 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
42 goes into 220 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3056.5
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 3056.52
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
42 goes into 160 3 times with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3056.523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 3056.5238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3056.5238
Subtract 0 from 40 to 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:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 3056.523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3056.5238095
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3056.52380952
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3056.52380952 with a remainder of 1.6e-08.
