We look at the division of 280681 by 74 
The aim is to understand the frequency of 74 in 280681.

On to step 1:
The number 74 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 74

Let's proceed to step 2:
74 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 74

On to step 3:
The number 74 fits into 280 3 times, leaving a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 222 from 280, we get 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 74

Let's proceed to step 4:
When dividing 586 by 74, we get 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 518 from 586 and we're left with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 74

On to step 5:
If we divide 688 by 74, we get 9 and a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 379.0
If we take 666 away from 688, we end up with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 74

Moving on to step 6:
If we divide 221 by 74, we get 2 and a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 3792.0
Subtracting 148 from 221 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 7:
When dividing 730 by 74, we get 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 3792.9
Deduct 666 from 730 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
The number 74 fits into 640 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3792.98
If we subtract 592 from 640, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
If we divide 480 by 74, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 3792.986
Subtract 444 from 480 to get 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 10:
If we divide 360 by 74, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 3792.9864
Subtract 296 from 360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
74 goes into 640 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3792.98648
Deduct 592 from 640 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
480 divided by 74 is 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 3792.986486
The remainder is 36 after subtracting 444 from 480.
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:
74 goes into 360 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 3792.9864864
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
640 divided by 74 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3792.98648648
If we take 592 away from 640, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 3792.98648648 with a remaining 4.8e-08.
