We divide 25190444 by 556
The aim is to understand the frequency of 556 in 25190444.

Step 1:
If we divide 2 by 556, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 556

Let's proceed to step 2:
When dividing 25 by 556, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 556

On to step 3:
When dividing 251 by 556, we get 0 with a remainder of 251.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 251, we end up with 251.
Fetch the next digit (9) from the dividend, attach it to 251 and continue: 2519 / 556

Step 4:
When dividing 2519 by 556, we get 4 with a remainder of 295.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 2224 from 2519 and we're left with 295.
Bring next digit (0) of the dividend behind the 295 and repeat the process: 2950 / 556

Going ahead to step 5:
2950 divided by 556 is 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 2780 from 2950, we get 170.
Append the next digit (4) from the dividend to 170 and continue with: 1704 / 556

Moving on to step 6:
556 can be fit into 1704 3 times, resulting in a remainder of 36.
The next digit of our result is 3. 
Result so far: 453.0
Subtracting 1668 from 1704 leaves us with 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 556

On to step 7:
When dividing 364 by 556, we get 0 with a remainder of 364.
Put 0 as the next digit of the answer. 
Result so far: 4530.0
If we subtract 0 from 364, we get 364.
Include the next digit (4) from the dividend after 364, then repeat: 3644 / 556

Advancing to step 8:
556 goes into 3644 6 times with a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 45306.0
Subtract 3336 from 3644 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 9:
When dividing 3080 by 556, we get 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 45306.5
Deduct 2780 from 3080 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
556 goes into 3000 5 times with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 45306.55
Subtract 2780 from 3000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 45306.55, with a leftover of 0.22.
