74397896 divided by 354 
The aim is to understand the frequency of 354 in 74397896.

Let's proceed to step 1:
7 divided by 354 is 0 with 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.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 354

Advancing to step 2:
The number 354 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 354

Advancing to step 3:
When dividing 743 by 354, we get 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 708 from 743 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 354

Advancing to step 4:
The number 354 fits into 359 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 354 from 359 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 354

Let's proceed to step 5:
354 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 210.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 354

Let's proceed to step 6:
578 divided by 354 is 1 with a remainder of 224.
The number 1 becomes the next digit in our result. 
Result so far: 2101.0
The remainder is 224 after subtracting 354 from 578.
Bring next digit (9) of the dividend behind the 224 and repeat the process: 2249 / 354

On to step 7:
354 can be fit into 2249 6 times, resulting in a remainder of 125.
The number 6 becomes the next digit in our result. 
Result so far: 21016.0
Subtract 2124 from 2249 to get 125.
Take the next digit (6) from the dividend and append it to 125, then repeat: 1256 / 354

Step 8:
If we divide 1256 by 354, we get 3 and a remainder of 194.
Record the quotient 3 as the next digit in the result. 
Result so far: 210163.0
If we subtract 1062 from 1256, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 9:
When dividing 1940 by 354, we get 5 with a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 210163.5
Deduct 1770 from 1940 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
354 can be fit into 1700 4 times, resulting in a remainder of 284.
The next digit of our result is 4. 
Result so far: 210163.54
Subtract 1416 from 1700 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 11:
When dividing 2840 by 354, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 210163.548
If we subtract 2832 from 2840, we get 8.
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:
If we divide 80 by 354, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 210163.548
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
When dividing 800 by 354, we get 2 with a remainder of 92.
The next digit of our result is 2. 
Result so far: 210163.54802
Subtract 708 from 800 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 14:
354 goes into 920 2 times with a remainder of 212.
The next digit of our result is 2. 
Result so far: 210163.548022
The remainder is 212 after subtracting 708 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

After the division, we end up with 210163.548022 and a remainder of 2.12e-05.
