We look at the division of 50466245 by 42 
The aim is to understand the frequency of 42 in 50466245.

Advancing to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 42

Moving on to step 2:
When dividing 50 by 42, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 50 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 42

Step 3:
42 can be fit into 84 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 84 from 84 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 42

Going ahead to step 4:
When dividing 6 by 42, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 42

Going ahead to step 5:
When dividing 66 by 42, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1201.0
Subtract 42 from 66 to get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 42

Advancing to step 6:
42 can be fit into 242 5 times, resulting in a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 12015.0
Subtracting 210 from 242 leaves us with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 42

Let's proceed to step 7:
42 goes into 324 7 times with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 120157.0
Subtract 294 from 324 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 42

Advancing to step 8:
When dividing 305 by 42, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1201577.0
Deduct 294 from 305 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
When dividing 110 by 42, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1201577.2
Subtracting 84 from 110 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
260 divided by 42 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1201577.26
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1201577.261
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
380 divided by 42 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1201577.2619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1201577.2619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
When dividing 200 by 42, we get 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 1201577.261904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 1201577.2619047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 16:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1201577.26190476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 1201577.26190476 and a remainder of 8e-09.
