We're dividing 738629 by 42 
The aim is to understand the frequency of 42 in 738629.

Going ahead to step 1:
7 divided by 42 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 42

Advancing to step 2:
42 can be fit into 73 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 73 leaves us with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 42

Advancing to step 3:
42 can be fit into 318 7 times, resulting in a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 24 after subtracting 294 from 318.
Append the next digit (6) from the dividend to 24 and continue with: 246 / 42

Let's proceed to step 4:
42 goes into 246 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 175.0
The remainder is 36 after subtracting 210 from 246.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 42

Step 5:
362 divided by 42 is 8 with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 1758.0
If we take 336 away from 362, we end up with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 42

Let's proceed to step 6:
42 goes into 269 6 times with a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 17586.0
The remainder is 17 after subtracting 252 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 42, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 17586.4
If we take 168 away from 170, 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 8:
20 divided by 42 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17586.4
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 9:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 17586.404
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.

Advancing to step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 17586.4047
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.

Advancing to step 11:
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: 17586.40476
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.

Moving on to step 12:
42 can be fit into 80 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 17586.404761
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:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 17586.4047619
Deduct 378 from 380 and we're left 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.

On to step 14:
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: 17586.4047619
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 17586.4047619, with a leftover of 2e-08.
