We're dividing 649673 by 42 
The aim is to understand the frequency of 42 in 649673.

On to step 1:
6 divided by 42 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 42

Let's proceed to step 2:
64 divided by 42 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 42 away from 64, we end up with 22.
Append the next digit (9) from the dividend to 22 and continue with: 229 / 42

Advancing to step 3:
42 goes into 229 5 times with a remainder of 19.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 210 from 229 leaves us with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 42

Moving on to step 4:
196 divided by 42 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
Deduct 168 from 196 and we're left with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 42

Advancing to step 5:
The number 42 fits into 287 6 times, leaving a remainder of 35.
The next digit of our result is 6. 
Result so far: 1546.0
If we subtract 252 from 287, we get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 42

Let's proceed to step 6:
If we divide 353 by 42, we get 8 and a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 15468.0
If we take 336 away from 353, 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.

On to step 7:
When dividing 170 by 42, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 15468.4
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.

Let's proceed to step 8:
42 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15468.4
Deduct 0 from 20 and we're left 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.

Going ahead to step 9:
The number 42 fits into 200 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 15468.404
If we take 168 away from 200, we end up with 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:
When dividing 320 by 42, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 15468.4047
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.

Going ahead to step 11:
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: 15468.40476
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.

Step 12:
42 goes into 80 1 times with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 15468.404761
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.

Going ahead to step 13:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 15468.4047619
If we take 378 away from 380, we end up 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:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15468.4047619
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.

In conclusion, the division gives 15468.4047619 with a balance of 2e-08.
