Let's divide 7890843 by 242
The aim is to understand the frequency of 242 in 7890843.

On to step 1:
If we divide 7 by 242, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 242

Going ahead to step 2:
242 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 242

Moving on to step 3:
242 can be fit into 789 3 times, resulting in a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 726 from 789, we get 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 242

On to step 4:
242 goes into 630 2 times with a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 484 away from 630, we end up with 146.
Include the next digit (8) from the dividend after 146, then repeat: 1468 / 242

On to step 5:
242 can be fit into 1468 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 326.0
Subtracting 1452 from 1468 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 242

Let's proceed to step 6:
242 can be fit into 164 0 times, resulting in a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 3260.0
The remainder is 164 after subtracting 0 from 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 242

Advancing to step 7:
242 can be fit into 1643 6 times, resulting in a remainder of 191.
Record the quotient 6 as the next digit in the result. 
Result so far: 32606.0
Deduct 1452 from 1643 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 8:
1910 divided by 242 is 7 with a remainder of 216.
The number 7 becomes the next digit in our result. 
Result so far: 32606.7
Subtract 1694 from 1910 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
If we divide 2160 by 242, we get 8 and a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 32606.78
Subtract 1936 from 2160 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
2240 divided by 242 is 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 32606.789
If we take 2178 away from 2240, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
If we divide 620 by 242, we get 2 and a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 32606.7892
If we take 484 away from 620, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 12:
If we divide 1360 by 242, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 32606.78925
The remainder is 150 after subtracting 1210 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
The number 242 fits into 1500 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 32606.789256
The remainder is 48 after subtracting 1452 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
When dividing 480 by 242, we get 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 32606.7892561
Subtracting 242 from 480 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 15:
When dividing 2380 by 242, we get 9 with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 32606.78925619
If we subtract 2178 from 2380, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final result is 32606.78925619 with a remainder of 2.02e-07.
