19646254 divided by 254 
The aim is to understand the frequency of 254 in 19646254.

Advancing to step 1:
254 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 254

On to step 2:
254 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 254

Going ahead to step 3:
254 goes into 196 0 times with a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 196 after subtracting 0 from 196.
Grab the next digit (4) from the dividend, add it to 196, then carry on: 1964 / 254

Moving on to step 4:
1964 divided by 254 is 7 with a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 1778 from 1964 to get 186.
Bring next digit (6) of the dividend behind the 186 and repeat the process: 1866 / 254

Let's proceed to step 5:
The number 254 fits into 1866 7 times, leaving a remainder of 88.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Deduct 1778 from 1866 and we're left with 88.
Grab the next digit (2) from the dividend, add it to 88, then carry on: 882 / 254

Advancing to step 6:
882 divided by 254 is 3 with a remainder of 120.
Write down 3 as next digit of the result. 
Result so far: 773.0
Subtracting 762 from 882 leaves us with 120.
Take the next digit (5) from the dividend and append it to 120, then repeat: 1205 / 254

Step 7:
When dividing 1205 by 254, we get 4 with a remainder of 189.
Record the quotient 4 as the next digit in the result. 
Result so far: 7734.0
Deduct 1016 from 1205 and we're left with 189.
Bring next digit (4) of the dividend behind the 189 and repeat the process: 1894 / 254

On to step 8:
254 goes into 1894 7 times with a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 77347.0
Deduct 1778 from 1894 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
254 goes into 1160 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 77347.4
Deduct 1016 from 1160 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 10:
When dividing 1440 by 254, we get 5 with a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 77347.45
If we take 1270 away from 1440, we end up 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.

Advancing to step 11:
1700 divided by 254 is 6 with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 77347.456
Deduct 1524 from 1700 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
If we divide 1760 by 254, we get 6 and a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 77347.4566
The remainder is 236 after subtracting 1524 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 77347.4566 with a remaining 0.00236.
