We're dividing 36851572 by 242 
The aim is to understand the frequency of 242 in 36851572.

Advancing to step 1:
242 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 242

Step 2:
The number 242 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 242

Going ahead to step 3:
The number 242 fits into 368 1 times, leaving a remainder of 126.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 242 from 368 leaves us with 126.
Grab the next digit (5) from the dividend, add it to 126, then carry on: 1265 / 242

Moving on to step 4:
If we divide 1265 by 242, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1210 from 1265 to get 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 242

Advancing to step 5:
The number 242 fits into 551 2 times, leaving a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 152.0
Subtract 484 from 551 to get 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 242

Step 6:
675 divided by 242 is 2 with a remainder of 191.
The next digit of our result is 2. 
Result so far: 1522.0
If we subtract 484 from 675, we get 191.
Fetch the next digit (7) from the dividend, attach it to 191 and continue: 1917 / 242

Step 7:
If we divide 1917 by 242, we get 7 and a remainder of 223.
Record the quotient 7 as the next digit in the result. 
Result so far: 15227.0
The remainder is 223 after subtracting 1694 from 1917.
Append the next digit (2) from the dividend to 223 and continue with: 2232 / 242

Going ahead to step 8:
242 goes into 2232 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 152279.0
Deduct 2178 from 2232 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
242 goes into 540 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 152279.2
If we take 484 away from 540, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
560 divided by 242 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 152279.22
Subtracting 484 from 560 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 152279.22 and a remainder of 0.076.
