Let's divide 123193 by 42
We want to divide 123193 by 42.

Advancing to step 1:
1 divided by 42 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 42

Let's proceed to step 2:
42 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 42

Moving on to step 3:
The number 42 fits into 123 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 84 from 123 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 42

Let's proceed to step 4:
When dividing 391 by 42, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 378 from 391, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 42

Let's proceed to step 5:
The number 42 fits into 139 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 293.0
If we take 126 away from 139, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 42

Moving on to step 6:
If we divide 133 by 42, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 2933.0
Deduct 126 from 133 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
When dividing 70 by 42, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 2933.1
Subtracting 42 from 70 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
42 can be fit into 280 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 2933.16
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
If we divide 280 by 42, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 2933.166
Subtract 252 from 280 to 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.

Our division results in 2933.166 with a remaining 0.0028.
