We look at the division of 86426596 by 242 
The aim is to understand the frequency of 242 in 86426596.

On to step 1:
The number 242 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 242

Going ahead to step 2:
When dividing 86 by 242, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 242

On to step 3:
864 divided by 242 is 3 with a remainder of 138.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 138 after subtracting 726 from 864.
Bring next digit (2) of the dividend behind the 138 and repeat the process: 1382 / 242

On to step 4:
If we divide 1382 by 242, we get 5 and a remainder of 172.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we subtract 1210 from 1382, we get 172.
Grab the next digit (6) from the dividend, add it to 172, then carry on: 1726 / 242

Going ahead to step 5:
When dividing 1726 by 242, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 357.0
Subtract 1694 from 1726 to get 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 242

Moving on to step 6:
When dividing 325 by 242, we get 1 with a remainder of 83.
The number 1 becomes the next digit in our result. 
Result so far: 3571.0
If we subtract 242 from 325, we get 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 242

Let's proceed to step 7:
The number 242 fits into 839 3 times, leaving a remainder of 113.
Use 3 as the next digit of our solution. 
Result so far: 35713.0
Subtract 726 from 839 to get 113.
Grab the next digit (6) from the dividend, add it to 113, then carry on: 1136 / 242

Moving on to step 8:
The number 242 fits into 1136 4 times, leaving a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 357134.0
If we subtract 968 from 1136, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 9:
242 can be fit into 1680 6 times, resulting in a remainder of 228.
The number 6 becomes the next digit in our result. 
Result so far: 357134.6
If we take 1452 away from 1680, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
242 can be fit into 2280 9 times, resulting in a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 357134.69
Subtract 2178 from 2280 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 11:
242 can be fit into 1020 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 357134.694
Subtract 968 from 1020 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
520 divided by 242 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 357134.6942
Subtracting 484 from 520 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
If we divide 360 by 242, we get 1 and a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 357134.69421
Subtract 242 from 360 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 14:
242 can be fit into 1180 4 times, resulting in a remainder of 212.
Write down 4 as next digit of the result. 
Result so far: 357134.694214
If we subtract 968 from 1180, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
If we divide 2120 by 242, we get 8 and a remainder of 184.
The next digit of our result is 8. 
Result so far: 357134.6942148
Subtracting 1936 from 2120 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 16:
The number 242 fits into 1840 7 times, leaving a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 357134.69421487
Deduct 1694 from 1840 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

After the division, we end up with 357134.69421487 and a remainder of 1.46e-07.
