659491 divided by 42 
We want to divide 659491 by 42.

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
If we take 0 away from 6, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 42

Going ahead to step 2:
When dividing 65 by 42, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 65 and we're left with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 42

On to step 3:
239 divided by 42 is 5 with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 210 from 239 and we're left with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 42

Advancing to step 4:
42 can be fit into 294 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Deduct 294 from 294 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 42

Moving on to step 5:
9 divided by 42 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 1570.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 42

Step 6:
If we divide 91 by 42, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 15702.0
Deduct 84 from 91 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 42 fits into 70 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 15702.1
If we subtract 42 from 70, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
280 divided by 42 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 15702.16
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
42 goes into 280 6 times with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 15702.166
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 15702.166, with a leftover of 0.0028.
