We look at the division of 243599 by 74 
The aim is to understand the frequency of 74 in 243599.

On to step 1:
2 divided by 74 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 74

On to step 2:
24 divided by 74 is 0 with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 74

Let's proceed to step 3:
74 goes into 243 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 222 from 243 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 74

Advancing to step 4:
If we divide 215 by 74, we get 2 and a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 148 away from 215, we end up with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 74

Advancing to step 5:
74 goes into 679 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 329.0
If we take 666 away from 679, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 74

Going ahead to step 6:
When dividing 139 by 74, we get 1 with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 3291.0
The remainder is 65 after subtracting 74 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
The number 74 fits into 650 8 times, leaving a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 3291.8
If we take 592 away from 650, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 3291.87
If we subtract 518 from 580, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
When dividing 620 by 74, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 3291.878
Subtract 592 from 620 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
When dividing 280 by 74, we get 3 with a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 3291.8783
The remainder is 58 after subtracting 222 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
The number 74 fits into 580 7 times, leaving a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 3291.87837
Deduct 518 from 580 and we're left 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.

Step 12:
When dividing 620 by 74, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 3291.878378
The remainder is 28 after subtracting 592 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
When dividing 280 by 74, we get 3 with a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 3291.8783783
Subtract 222 from 280 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
74 goes into 580 7 times with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 3291.87837837
The remainder is 62 after subtracting 518 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 3291.87837837 with a balance of 6.2e-08.
