We divide 39511 by 42
The aim is to understand the frequency of 42 in 39511.

Advancing to step 1:
42 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 42

Step 2:
When dividing 39 by 42, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 42

Step 3:
42 goes into 395 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 378 from 395 to get 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 42

Let's proceed to step 4:
171 divided by 42 is 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 168 from 171 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 42

Going ahead to step 5:
31 divided by 42 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 940.0
Subtracting 0 from 31 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 6:
If we divide 310 by 42, we get 7 and a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 940.7
Subtract 294 from 310 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 940.73
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 940.738
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 940.738
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.

On to step 10:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 940.73809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
42 goes into 220 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 940.738095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 940.7380952
Deduct 84 from 100 and we're left 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.

Advancing to step 13:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 940.73809523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 940.73809523 with a remainder of 3.4e-08.
