233923 ÷ 42 
We want to divide 233923 by 42.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 42

Advancing to step 2:
42 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 42

Let's proceed to step 3:
The number 42 fits into 233 5 times, leaving a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 210 away from 233, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 42

On to step 4:
42 goes into 239 5 times with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
The remainder is 29 after subtracting 210 from 239.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 42

Let's proceed to step 5:
42 can be fit into 292 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
Subtracting 252 from 292 leaves us with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 42

Moving on to step 6:
42 goes into 403 9 times with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 5569.0
Subtracting 378 from 403 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
42 goes into 250 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 5569.5
If we take 210 away from 250, we end up 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 8:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 5569.59
Subtracting 378 from 400 leaves us 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.

Advancing to step 9:
220 divided by 42 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5569.595
If we take 210 away from 220, we end up 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 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 5569.5952
Subtracting 84 from 100 leaves us 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.

Advancing to step 11:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 5569.59523
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.

On to step 12:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 5569.595238
Deduct 336 from 340 and we're left with 4.
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 13:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5569.595238
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.

Let's proceed to step 14:
400 divided by 42 is 9 with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 5569.59523809
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.

The final outcome is 5569.59523809, with a leftover of 2.2e-08.
