Let's divide 660658 by 42
We want to figure out the number of times 660658 can be divided by 42.

Let's proceed to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 42

Advancing to step 2:
42 goes into 66 1 times with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 42 from 66 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 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
Deduct 210 from 240 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 42

Going ahead to step 4:
42 can be fit into 306 7 times, resulting in a remainder of 12.
The next digit of our result is 7. 
Result so far: 157.0
If we subtract 294 from 306, we get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 42

Let's proceed to step 5:
125 divided by 42 is 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 1572.0
Deduct 84 from 125 and we're left with 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 42

Step 6:
42 can be fit into 418 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 15729.0
Subtracting 378 from 418 leaves us with 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 7:
42 goes into 400 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 15729.9
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15729.95
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15729.952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 15729.9523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
42 goes into 340 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 15729.95238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15729.95238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 15729.9523809
Deduct 378 from 400 and we're left with 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 14:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15729.95238095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 15729.95238095 with a remaining 1e-08.
