Let's divide 89251 by 42
The aim is to understand the frequency of 42 in 89251.

Going ahead to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 42

On to step 2:
42 goes into 89 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 89 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 42

Advancing to step 3:
42 can be fit into 52 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 10 after subtracting 42 from 52.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 42

Advancing to step 4:
The number 42 fits into 105 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 212.0
If we subtract 84 from 105, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 42

Going ahead to step 5:
42 goes into 211 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2125.0
Subtract 210 from 211 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
10 divided by 42 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2125.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 42, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 2125.02
If we subtract 84 from 100, we 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.

Let's proceed to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 2125.023
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.

Step 9:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2125.0238
If we take 336 away from 340, we end up 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.

Let's proceed to step 10:
When dividing 40 by 42, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2125.0238
Subtract 0 from 40 to 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 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 2125.023809
Subtracting 378 from 400 leaves us 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 12:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 2125.0238095
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 13:
100 divided by 42 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2125.02380952
Subtract 84 from 100 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.

Our division results in 2125.02380952 with a remaining 1.6e-08.
