143848 divided by 42 
We want to figure out the number of times 143848 can be divided by 42.

On to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 42

Advancing to step 2:
The number 42 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 42

Moving on to step 3:
42 can be fit into 143 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 126 from 143 leaves us with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 42

Advancing to step 4:
178 divided by 42 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 168 from 178, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 42

Step 5:
42 goes into 104 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 342.0
The remainder is 20 after subtracting 84 from 104.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 42

Moving on to step 6:
208 divided by 42 is 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3424.0
If we subtract 168 from 208, 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.

Let's proceed to step 7:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 3424.9
Subtract 378 from 400 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.

On to step 8:
220 divided by 42 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3424.95
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 3424.952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 3424.9523
If we subtract 126 from 160, we get 34.
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 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3424.95238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 42 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3424.95238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 42 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 3424.9523809
If we subtract 378 from 400, we 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 14:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3424.95238095
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.

The final result is 3424.95238095 with a remainder of 1e-08.
