We look at the division of 41660776 by 42 
The aim is to understand the frequency of 42 in 41660776.

Going ahead to step 1:
42 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 42

Let's proceed to step 2:
The number 42 fits into 41 0 times, leaving a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 42

Advancing to step 3:
416 divided by 42 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 378 from 416, we get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 42

Let's proceed to step 4:
42 goes into 386 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 378 from 386 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 42

Going ahead to step 5:
42 goes into 80 1 times with a remainder of 38.
The next digit of our result is 1. 
Result so far: 991.0
Subtracting 42 from 80 leaves us with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 42

Let's proceed to step 6:
42 can be fit into 387 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9919.0
Deduct 378 from 387 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 42

Advancing to step 7:
If we divide 97 by 42, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 99192.0
If we take 84 away from 97, we end up with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 42

Let's proceed to step 8:
42 goes into 136 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 991923.0
If we subtract 126 from 136, we 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.

Advancing to step 9:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 991923.2
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 10:
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: 991923.23
Subtracting 126 from 160 leaves us 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.

Step 11:
42 goes into 340 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 991923.238
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.

Step 12:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 991923.238
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.

Advancing to step 13:
When dividing 400 by 42, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 991923.23809
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 14:
42 goes into 220 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 991923.238095
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.

On to step 15:
42 goes into 100 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 991923.2380952
Deduct 84 from 100 and we're left 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.

Going ahead to step 16:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 991923.23809523
The remainder is 34 after subtracting 126 from 160.
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 991923.23809523, and the remainder is 3.4e-08.
