We look at the division of 578258 by 74 
The aim is to understand the frequency of 74 in 578258.

Moving on to step 1:
5 divided by 74 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 74

Step 2:
If we divide 57 by 74, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 74

On to step 3:
When dividing 578 by 74, we get 7 with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 518 from 578 leaves us with 60.
Bring next digit (2) of the dividend behind the 60 and repeat the process: 602 / 74

Advancing to step 4:
602 divided by 74 is 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 592 from 602, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 74

Let's proceed to step 5:
105 divided by 74 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
Subtract 74 from 105 to get 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 74

Step 6:
74 can be fit into 318 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 7814.0
Subtracting 296 from 318 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 74, we get 2 and a remainder of 72.
The next digit of our result is 2. 
Result so far: 7814.2
The remainder is 72 after subtracting 148 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
74 goes into 720 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 7814.29
The remainder is 54 after subtracting 666 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
If we divide 540 by 74, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7814.297
If we subtract 518 from 540, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
74 goes into 220 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 7814.2972
If we subtract 148 from 220, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
74 can be fit into 720 9 times, resulting in a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 7814.29729
Subtracting 666 from 720 leaves us 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.

Let's proceed to step 12:
If we divide 540 by 74, we get 7 and a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7814.297297
Subtracting 518 from 540 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
74 can be fit into 220 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 7814.2972972
Deduct 148 from 220 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
74 goes into 720 9 times with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 7814.29729729
The remainder is 54 after subtracting 666 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 7814.29729729 with a remaining 5.4e-08.
