Let's divide 837952 by 42
The aim is to understand the frequency of 42 in 837952.

Going ahead to step 1:
If we divide 8 by 42, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 42

Step 2:
If we divide 83 by 42, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 83 leaves us with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 42

Going ahead to step 3:
417 divided by 42 is 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 378 away from 417, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 42

Advancing to step 4:
42 goes into 399 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
If we subtract 378 from 399, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 42

Going ahead to step 5:
42 can be fit into 215 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1995.0
Deduct 210 from 215 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 42

Step 6:
42 goes into 52 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 19951.0
Subtract 42 from 52 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 19951.2
If we subtract 84 from 100, we 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 8:
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: 19951.23
Subtract 126 from 160 to 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 9:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 19951.238
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.

Let's proceed to step 10:
When dividing 40 by 42, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 19951.238
Subtract 0 from 40 to get 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 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 19951.23809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19951.238095
If we take 210 away from 220, we end up 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.

Step 13:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 19951.2380952
If we subtract 84 from 100, we 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.

Going ahead to step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 19951.23809523
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.

The quotient of the division is 19951.23809523, and the remainder is 3.4e-08.
