Let's divide 667403 by 42
We're looking to find how many times 42 goes into 667403.

Moving on to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 42

Advancing to step 2:
42 can be fit into 66 1 times, resulting in a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 24 after subtracting 42 from 66.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 42

Going ahead to step 3:
If we divide 247 by 42, we get 5 and a remainder of 37.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 210 from 247 to get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 42

Let's proceed to step 4:
374 divided by 42 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 158.0
The remainder is 38 after subtracting 336 from 374.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 42

On to step 5:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1589.0
The remainder is 2 after subtracting 378 from 380.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 42

Moving on to step 6:
42 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 15890.0
If we subtract 0 from 23, we 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.

On to step 7:
42 can be fit into 230 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 15890.5
If we take 210 away from 230, we end up 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.

Going ahead to step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 15890.54
If we take 168 away from 200, we end up 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.

Advancing to step 9:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 15890.547
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
42 goes into 260 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 15890.5476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The next digit of our result is 1. 
Result so far: 15890.54761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 15890.547619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15890.547619
Deduct 0 from 20 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.

Advancing to step 14:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 15890.54761904
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.

Our division results in 15890.54761904 with a remaining 3.2e-08.
