923397 divided by 42 
Our goal is to divide 923397 by 42.

Step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 42

Advancing to step 2:
When dividing 92 by 42, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 84 from 92, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 42

Let's proceed to step 3:
If we divide 83 by 42, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 42 from 83 and we're left with 41.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 42

Moving on to step 4:
When dividing 413 by 42, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 219.0
Subtracting 378 from 413 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 42

Let's proceed to step 5:
If we divide 359 by 42, we get 8 and a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 2198.0
Deduct 336 from 359 and we're left with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 42

Going ahead to step 6:
If we divide 237 by 42, we get 5 and a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 21985.0
If we take 210 away from 237, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
270 divided by 42 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 21985.6
Subtracting 252 from 270 leaves us 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.

Going ahead to step 8:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 21985.64
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
42 goes into 120 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 21985.642
Subtracting 84 from 120 leaves us 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.

Advancing to step 10:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 21985.6428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 21985.64285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 21985.642857
If we take 294 away from 300, we end up with 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 13:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 21985.6428571
Subtracting 42 from 60 leaves us 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.

Advancing to step 14:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 21985.64285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 21985.64285714, and the remainder is 1.2e-08.
