Let's divide 660817 by 42
Let's see how many times 42 fits into 660817.

Going ahead to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 42

On 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
Subtract 42 from 66 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 42

Going ahead to step 3:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 210 from 240 to get 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 42

Going ahead to step 4:
If we divide 308 by 42, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 157.0
If we subtract 294 from 308, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 42

Advancing to step 5:
42 can be fit into 141 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 1573.0
Subtracting 126 from 141 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 42

Step 6:
The number 42 fits into 157 3 times, leaving a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 15733.0
The remainder is 31 after subtracting 126 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
If we divide 310 by 42, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 15733.7
If we subtract 294 from 310, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 15733.73
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 42 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 15733.738
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15733.738
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 15733.73809
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
When dividing 220 by 42, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15733.738095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 15733.7380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 15733.73809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 15733.73809523 with a remaining 3.4e-08.
