We divide 31223400 by 42
Our goal is to divide 31223400 by 42.

Moving on to step 1:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 42

Advancing to step 2:
If we divide 31 by 42, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 42

Step 3:
If we divide 312 by 42, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 294 from 312 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 42

Advancing to step 4:
If we divide 182 by 42, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtract 168 from 182 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 42

On to step 5:
42 can be fit into 143 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 743.0
If we subtract 126 from 143, we get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 42

Step 6:
42 can be fit into 174 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 7434.0
If we subtract 168 from 174, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 42

On to step 7:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 74341.0
Subtract 42 from 60 to get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 42

Advancing to step 8:
When dividing 180 by 42, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 743414.0
Subtracting 168 from 180 leaves us 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.

Let's proceed to step 9:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 743414.2
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 743414.28
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 11:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 743414.285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
300 divided by 42 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 743414.2857
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.

Let's proceed to step 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 743414.28571
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.

Going ahead to step 14:
42 goes into 180 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 743414.285714
Subtracting 168 from 180 leaves us 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.

Step 15:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 743414.2857142
Subtract 84 from 120 to 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.

Step 16:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 743414.28571428
If we subtract 336 from 360, we 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.

The quotient of the division is 743414.28571428, and the remainder is 2.4e-08.
