We look at the division of 864896 by 74 
The aim is to understand the frequency of 74 in 864896.

Step 1:
If we divide 8 by 74, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 74

On to step 2:
If we divide 86 by 74, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 74 from 86 and we're left with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 74

Going ahead to step 3:
74 can be fit into 124 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 74 from 124 and we're left with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 74

Let's proceed to step 4:
If we divide 508 by 74, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 444 from 508 to get 64.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 74

Going ahead to step 5:
The number 74 fits into 649 8 times, leaving a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 1168.0
Deduct 592 from 649 and we're left with 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 74

Moving on to step 6:
74 can be fit into 576 7 times, resulting in a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 11687.0
Deduct 518 from 576 and we're left 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.

Going ahead to step 7:
74 can be fit into 580 7 times, resulting in a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 11687.7
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.

Advancing to step 8:
620 divided by 74 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 11687.78
Subtracting 592 from 620 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 74, we get 3 and a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 11687.783
If we take 222 away from 280, 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.

Advancing to step 10:
74 can be fit into 580 7 times, resulting in a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 11687.7837
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.

On to step 11:
74 goes into 620 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 11687.78378
Subtracting 592 from 620 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 74 is 3 with a remainder of 58.
Use 3 as the next digit of our solution. 
Result so far: 11687.783783
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.

Step 13:
When dividing 580 by 74, we get 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 11687.7837837
If we take 518 away from 580, we end up 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 14:
620 divided by 74 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 11687.78378378
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.

Our division results in 11687.78378378 with a remaining 2.8e-08.
