Let's divide 256349 by 42
We want to figure out the number of times 256349 can be divided by 42.

On to step 1:
42 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

Step 2:
42 goes into 25 0 times with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 42

Step 3:
The number 42 fits into 256 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 252 away from 256, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 42

Advancing to step 4:
The number 42 fits into 43 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
The remainder is 1 after subtracting 42 from 43.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 42

Let's proceed to step 5:
42 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 610.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 42

Step 6:
42 can be fit into 149 3 times, resulting in a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 6103.0
Subtract 126 from 149 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
The number 42 fits into 230 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 6103.5
The remainder is 20 after subtracting 210 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 6103.54
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 42, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 6103.547
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 6103.5476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
42 can be fit into 80 1 times, resulting in a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 6103.54761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 6103.547619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6103.547619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 6103.54761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 6103.54761904 and a remainder of 3.2e-08.
