We divide 315883 by 42
The aim is to understand the frequency of 42 in 315883.

Moving on to step 1:
42 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 42

Let's proceed to step 2:
42 goes into 31 0 times with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 42

On to step 3:
42 goes into 315 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 294 away from 315, we end up with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 42

Moving on to step 4:
42 can be fit into 218 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 210 from 218, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 42

Let's proceed to step 5:
If we divide 88 by 42, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 752.0
Subtract 84 from 88 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 42

Advancing to step 6:
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: 7521.0
If we subtract 42 from 43, 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:
The number 42 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7521.0
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.

On to step 8:
When dividing 100 by 42, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 7521.02
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.

Advancing to step 9:
160 divided by 42 is 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 7521.023
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.

Advancing to step 10:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7521.0238
If we subtract 336 from 340, we 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.

Let's proceed to step 11:
When dividing 40 by 42, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7521.0238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The next digit of our result is 9. 
Result so far: 7521.023809
If we subtract 378 from 400, we 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.

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: 7521.0238095
Deduct 210 from 220 and we're left 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 14:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 7521.02380952
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.

The final result is 7521.02380952 with a remainder of 1.6e-08.
