We divide 11391 by 42
The aim is to understand the frequency of 42 in 11391.

Advancing to step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 42

Let's proceed to step 2:
The number 42 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 42

On to step 3:
42 can be fit into 113 2 times, resulting in a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 84 from 113 to get 29.
Fetch the next digit (9) from the dividend, attach it to 29 and continue: 299 / 42

Advancing to step 4:
The number 42 fits into 299 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 5 after subtracting 294 from 299.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 42

Advancing to step 5:
42 can be fit into 51 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.0
Deduct 42 from 51 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
90 divided by 42 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 271.2
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 42, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 271.21
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 271.214
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 271.2142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
42 goes into 360 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 271.21428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 271.214285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 271.2142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 271.21428571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 271.21428571, and the remainder is 1.8e-08.
