Let's divide 193239 by 42
Our goal is to divide 193239 by 42.

Step 1:
If we divide 1 by 42, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 42

Let's proceed to step 2:
42 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 42

Step 3:
42 can be fit into 193 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 25 after subtracting 168 from 193.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 42

Let's proceed to step 4:
42 can be fit into 252 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 46.0
If we take 252 away from 252, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 42

Let's proceed to step 5:
When dividing 3 by 42, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 42

Advancing to step 6:
39 divided by 42 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 4600.0
If we subtract 0 from 39, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 42, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 4600.9
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 4600.92
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
42 goes into 360 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4600.928
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 4600.9285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4600.92857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 4600.928571
If we take 42 away from 60, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 4600.9285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 4600.92857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 4600.92857142 with a remaining 3.6e-08.
