We look at the division of 25564003 by 354 
The aim is to understand the frequency of 354 in 25564003.

Moving on to step 1:
The number 354 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 354

Step 2:
25 divided by 354 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 354

Going ahead to step 3:
The number 354 fits into 255 0 times, leaving a remainder of 255.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 255 to get 255.
Fetch the next digit (6) from the dividend, attach it to 255 and continue: 2556 / 354

Step 4:
2556 divided by 354 is 7 with a remainder of 78.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 2478 from 2556 leaves us with 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 354

Step 5:
784 divided by 354 is 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 708 from 784 to get 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 354

Step 6:
The number 354 fits into 760 2 times, leaving a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 722.0
Deduct 708 from 760 and we're left with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 354

Going ahead to step 7:
520 divided by 354 is 1 with a remainder of 166.
Write down 1 as next digit of the result. 
Result so far: 7221.0
Subtract 354 from 520 to get 166.
Bring next digit (3) of the dividend behind the 166 and repeat the process: 1663 / 354

Let's proceed to step 8:
When dividing 1663 by 354, we get 4 with a remainder of 247.
Record the quotient 4 as the next digit in the result. 
Result so far: 72214.0
If we subtract 1416 from 1663, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 9:
354 can be fit into 2470 6 times, resulting in a remainder of 346.
The number 6 becomes the next digit in our result. 
Result so far: 72214.6
Deduct 2124 from 2470 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 10:
The number 354 fits into 3460 9 times, leaving a remainder of 274.
Put 9 as the next digit of the answer. 
Result so far: 72214.69
The remainder is 274 after subtracting 3186 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
354 goes into 2740 7 times with a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 72214.697
Subtract 2478 from 2740 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 12:
2620 divided by 354 is 7 with a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 72214.6977
Subtract 2478 from 2620 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The quotient of the division is 72214.6977, and the remainder is 0.00142.
