We look at the division of 769835 by 42 
The aim is to understand the frequency of 42 in 769835.

On to step 1:
If we divide 7 by 42, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 42

Advancing to step 2:
42 goes into 76 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 76 and we're left with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 42

On to step 3:
When dividing 349 by 42, we get 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 336 away from 349, we end up with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 42

Going ahead to step 4:
138 divided by 42 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 183.0
If we take 126 away from 138, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 42

Advancing to step 5:
The number 42 fits into 123 2 times, leaving a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 1832.0
Subtract 84 from 123 to get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 42

Moving on to step 6:
If we divide 395 by 42, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 18329.0
If we take 378 away from 395, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
42 can be fit into 170 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 18329.4
Subtracting 168 from 170 leaves us with 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 8:
When dividing 20 by 42, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18329.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 18329.404
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 18329.4047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 18329.40476
Subtract 252 from 260 to 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 12:
The number 42 fits into 80 1 times, leaving a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 18329.404761
Deduct 42 from 80 and we're left 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.

Step 13:
When dividing 380 by 42, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 18329.4047619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18329.4047619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 18329.4047619 with a balance of 2e-08.
