659964 ÷ 42 
We want to figure out the number of times 659964 can be divided by 42.

Going ahead to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 42

Advancing to step 2:
If we divide 65 by 42, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 23 after subtracting 42 from 65.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 42

Going ahead to step 3:
If we divide 239 by 42, we get 5 and a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 29 after subtracting 210 from 239.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 42

Going ahead to step 4:
If we divide 299 by 42, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we take 294 away from 299, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 42

On to step 5:
42 can be fit into 56 1 times, resulting in a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1571.0
Subtracting 42 from 56 leaves us with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 42

Step 6:
If we divide 144 by 42, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 15713.0
If we take 126 away from 144, 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.

Advancing to step 7:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 15713.4
Deduct 168 from 180 and we're left 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.

Advancing to step 8:
42 goes into 120 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15713.42
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 15713.428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
If we divide 240 by 42, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 15713.4285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 15713.42857
Deduct 294 from 300 and we're left 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.

Advancing to step 12:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 15713.428571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 15713.4285714
If we take 168 away from 180, we end up 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 14:
120 divided by 42 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 15713.42857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 15713.42857142, and the remainder is 3.6e-08.
