We look at the division of 17974739 by 240 
The aim is to understand the frequency of 240 in 17974739.

Step 1:
1 divided by 240 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 240

Step 2:
If we divide 17 by 240, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 240

Step 3:
240 can be fit into 179 0 times, resulting in a remainder of 179.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 179 to get 179.
Include the next digit (7) from the dividend after 179, then repeat: 1797 / 240

Let's proceed to step 4:
When dividing 1797 by 240, we get 7 with a remainder of 117.
The next digit of our result is 7. 
Result so far: 7.0
If we take 1680 away from 1797, we end up with 117.
Fetch the next digit (4) from the dividend, attach it to 117 and continue: 1174 / 240

Step 5:
If we divide 1174 by 240, we get 4 and a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 960 from 1174 leaves us with 214.
Append the next digit (7) from the dividend to 214 and continue with: 2147 / 240

Let's proceed to step 6:
240 can be fit into 2147 8 times, resulting in a remainder of 227.
The next digit of our result is 8. 
Result so far: 748.0
If we subtract 1920 from 2147, we get 227.
Fetch the next digit (3) from the dividend, attach it to 227 and continue: 2273 / 240

Going ahead to step 7:
240 can be fit into 2273 9 times, resulting in a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 7489.0
If we subtract 2160 from 2273, we get 113.
Append the next digit (9) from the dividend to 113 and continue with: 1139 / 240

Step 8:
240 can be fit into 1139 4 times, resulting in a remainder of 179.
Put 4 as the next digit of the answer. 
Result so far: 74894.0
Subtracting 960 from 1139 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
When dividing 1790 by 240, we get 7 with a remainder of 110.
The next digit of our result is 7. 
Result so far: 74894.7
Subtract 1680 from 1790 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
When dividing 1100 by 240, we get 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 74894.74
If we subtract 960 from 1100, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
1400 divided by 240 is 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 74894.745
Subtract 1200 from 1400 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
240 can be fit into 2000 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 74894.7458
Subtract 1920 from 2000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 240, we get 3 and a remainder of 80.
The next digit of our result is 3. 
Result so far: 74894.74583
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
The number 240 fits into 800 3 times, leaving a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 74894.745833
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 74894.745833 and a remainder of 8e-06.
