90856 divided by 42 
The aim is to understand the frequency of 42 in 90856.

Step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 42

Advancing to step 2:
42 goes into 90 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 84 from 90 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 42

Let's proceed to step 3:
When dividing 68 by 42, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 42 from 68, we get 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 42

Let's proceed to step 4:
The number 42 fits into 265 6 times, leaving a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtracting 252 from 265 leaves us with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 42

Let's proceed to step 5:
If we divide 136 by 42, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 2163.0
If we take 126 away from 136, we end up 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.

Moving on to step 6:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2163.2
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.

Let's proceed to step 7:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 2163.23
Subtract 126 from 160 to 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.

Going ahead to step 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 2163.238
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 9:
40 divided by 42 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2163.238
If we take 0 away from 40, we end up 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.

Going ahead to step 10:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 2163.23809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
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: 2163.238095
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.

On to step 12:
When dividing 100 by 42, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2163.2380952
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.

Let's proceed to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 2163.23809523
Deduct 126 from 160 and we're left 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.

Our division results in 2163.23809523 with a remaining 3.4e-08.
