We look at the division of 755398 by 74 
The aim is to understand the frequency of 74 in 755398.

On to step 1:
The number 74 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 74

Moving on to step 2:
If we divide 75 by 74, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 74 from 75 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 74

Going ahead to step 3:
The number 74 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 74

Moving on to step 4:
74 goes into 153 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 102.0
If we subtract 148 from 153, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 74

Advancing to step 5:
When dividing 59 by 74, we get 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
Subtract 0 from 59 to get 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 74

Advancing to step 6:
If we divide 598 by 74, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10208.0
If we take 592 away from 598, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 74 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10208.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
74 goes into 600 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 10208.08
If we take 592 away from 600, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 74, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 10208.081
Subtracting 74 from 80 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
If we divide 60 by 74, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10208.081
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
74 can be fit into 600 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10208.08108
The remainder is 8 after subtracting 592 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
When dividing 80 by 74, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 10208.081081
If we take 74 away from 80, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 74 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10208.081081
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
If we divide 600 by 74, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 10208.08108108
If we take 592 away from 600, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10208.08108108 and a remainder of 8e-09.
