We look at the division of 256999 by 42 
We want to figure out the number of times 256999 can be divided by 42.

Moving on to step 1:
42 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 42

Advancing to step 2:
42 goes into 25 0 times with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 42

Going ahead to step 3:
When dividing 256 by 42, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 252 from 256 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 42

Advancing to step 4:
42 goes into 49 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 42 from 49, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 42

Advancing to step 5:
The number 42 fits into 79 1 times, leaving a remainder of 37.
The next digit of our result is 1. 
Result so far: 611.0
Deduct 42 from 79 and we're left with 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 42

Step 6:
If we divide 379 by 42, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 6119.0
If we subtract 378 from 379, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 42 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6119.0
The remainder is 10 after subtracting 0 from 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 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 6119.02
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.

Step 9:
42 goes into 160 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 6119.023
If we take 126 away from 160, we end up 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.

Going ahead to step 10:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6119.0238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6119.0238
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.

Let's proceed to step 12:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 6119.023809
If we take 378 away from 400, we end up 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.

Advancing to step 13:
If we divide 220 by 42, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 6119.0238095
Subtracting 210 from 220 leaves us 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.

On to step 14:
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: 6119.02380952
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.

The final result is 6119.02380952 with a remainder of 1.6e-08.
