We look at the division of 238657 by 42 
Let's see how many times 42 fits into 238657.

Step 1:
42 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

On to step 2:
When dividing 23 by 42, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 42

On to step 3:
The number 42 fits into 238 5 times, leaving a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 210 from 238 to get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 42

Moving on to step 4:
When dividing 286 by 42, we get 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 56.0
The remainder is 34 after subtracting 252 from 286.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 42

Advancing to step 5:
If we divide 345 by 42, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 568.0
If we subtract 336 from 345, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 42

Step 6:
97 divided by 42 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 5682.0
Subtracting 84 from 97 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
42 can be fit into 130 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 5682.3
If we take 126 away from 130, we end up with 4.
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 8:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5682.3
Subtracting 0 from 40 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.

Let's proceed to step 9:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 5682.309
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.

Step 10:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5682.3095
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.

Advancing to step 11:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 5682.30952
Subtracting 84 from 100 leaves us 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 12:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 5682.309523
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.

On to step 13:
When dividing 340 by 42, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 5682.3095238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5682.3095238
If we take 0 away from 40, we end up 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.

The final outcome is 5682.3095238, with a leftover of 4e-08.
