257133 divided by 42 
The aim is to understand the frequency of 42 in 257133.

Step 1:
42 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
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

On to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 42

Step 3:
257 divided by 42 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 5 after subtracting 252 from 257.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 42

Going ahead to step 4:
42 goes into 51 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we subtract 42 from 51, we get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 42

Going ahead to step 5:
If we divide 93 by 42, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 612.0
Subtracting 84 from 93 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 42

Moving on to step 6:
The number 42 fits into 93 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 6122.0
Subtracting 84 from 93 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 42, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6122.2
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
42 goes into 60 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 6122.21
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
If we divide 180 by 42, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 6122.214
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 6122.2142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 6122.21428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6122.214285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 6122.2142857
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 6122.21428571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6122.21428571, and the remainder is 1.8e-08.
