We divide 621487 by 42
The aim is to understand the frequency of 42 in 621487.

Let's proceed to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 42

Step 2:
If we divide 62 by 42, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 20 after subtracting 42 from 62.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 42

On to step 3:
If we divide 201 by 42, we get 4 and a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 168 from 201 to get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 42

Advancing to step 4:
If we divide 334 by 42, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Deduct 294 from 334 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 42

Let's proceed to step 5:
408 divided by 42 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 1479.0
If we take 378 away from 408, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 42

On to step 6:
42 goes into 307 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 14797.0
If we take 294 away from 307, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 42 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 14797.3
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 14797.3
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 14797.309
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 42, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 14797.3095
Deduct 210 from 220 and we're left 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.

Let's proceed to step 11:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 14797.30952
Subtracting 84 from 100 leaves us 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.

Step 12:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 14797.309523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 14797.3095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 14797.3095238
Deduct 0 from 40 and we're left 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.

In conclusion, the division gives 14797.3095238 with a balance of 4e-08.
