Let's divide 386423 by 42
We want to figure out the number of times 386423 can be divided by 42.

Moving on to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 42

Advancing to step 2:
38 divided by 42 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 42

Moving on to step 3:
42 can be fit into 386 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 378 from 386 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 42

Moving on to step 4:
42 can be fit into 84 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 84 from 84 and we're left with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 42

Let's proceed to step 5:
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: 920.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

Going ahead to step 6:
42 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 9200.0
Subtract 0 from 23 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
42 goes into 230 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 9200.5
Deduct 210 from 230 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 9200.54
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
42 goes into 320 7 times with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 9200.547
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 42, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 9200.5476
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 9200.54761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 9200.547619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9200.547619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 42, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 9200.54761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 9200.54761904 and a remainder of 3.2e-08.
