Let's divide 25458946 by 42
The aim is to understand the frequency of 42 in 25458946.

Moving on to step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 42

On to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 42

Advancing to step 3:
254 divided by 42 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 2 after subtracting 252 from 254.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

Advancing to step 4:
When dividing 25 by 42, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 60.0
Subtract 0 from 25 to get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 42

Let's proceed to step 5:
258 divided by 42 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 606.0
If we subtract 252 from 258, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 42

Step 6:
69 divided by 42 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 6061.0
Subtract 42 from 69 to get 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 42

Advancing to step 7:
42 goes into 274 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 60616.0
If we subtract 252 from 274, we get 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 42

Advancing to step 8:
The number 42 fits into 226 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 606165.0
If we take 210 away from 226, 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.

On to step 9:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 606165.3
Deduct 126 from 160 and we're left 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.

Let's proceed to step 10:
340 divided by 42 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 606165.38
If we take 336 away from 340, 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.

On to step 11:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 606165.38
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.

Step 12:
If we divide 400 by 42, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 606165.3809
Subtract 378 from 400 to get 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:
The number 42 fits into 220 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 606165.38095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 606165.380952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 606165.3809523
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.

Going ahead to step 16:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 606165.38095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 606165.38095238, and the remainder is 4e-09.
