666605 divided by 42 
We're looking to find how many times 42 goes into 666605.

Advancing to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 42

Going ahead to step 2:
If we divide 66 by 42, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 66 to get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 42

Going ahead to step 3:
The number 42 fits into 246 5 times, leaving a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 210 from 246 to get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 42

Step 4:
366 divided by 42 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we take 336 away from 366, we end up with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 42

Step 5:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1587.0
Subtract 294 from 300 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 42

Let's proceed to step 6:
If we divide 65 by 42, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 15871.0
If we subtract 42 from 65, 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.

Going ahead to step 7:
If we divide 230 by 42, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15871.5
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.

Let's proceed to step 8:
200 divided by 42 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 15871.54
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.

Let's proceed to step 9:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 15871.547
Subtract 294 from 320 to 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.

Advancing to step 10:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 15871.5476
Subtracting 252 from 260 leaves us 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.

Step 11:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 15871.54761
If we subtract 42 from 80, we 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.

Let's proceed to step 12:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 15871.547619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 15871.547619
If we take 0 away from 20, 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.

On to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 15871.54761904
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.

Our division results in 15871.54761904 with a remaining 3.2e-08.
