We're dividing 12642916 by 253 
The aim is to understand the frequency of 253 in 12642916.

On to step 1:
253 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 253

Advancing to step 2:
253 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 253

Going ahead to step 3:
The number 253 fits into 126 0 times, leaving a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 126, we end up with 126.
Bring next digit (4) of the dividend behind the 126 and repeat the process: 1264 / 253

Let's proceed to step 4:
253 can be fit into 1264 4 times, resulting in a remainder of 252.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1012 from 1264 and we're left with 252.
Grab the next digit (2) from the dividend, add it to 252, then carry on: 2522 / 253

Going ahead to step 5:
253 can be fit into 2522 9 times, resulting in a remainder of 245.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 2277 away from 2522, we end up with 245.
Include the next digit (9) from the dividend after 245, then repeat: 2459 / 253

On to step 6:
If we divide 2459 by 253, we get 9 and a remainder of 182.
Write down 9 as next digit of the result. 
Result so far: 499.0
Subtracting 2277 from 2459 leaves us with 182.
Include the next digit (1) from the dividend after 182, then repeat: 1821 / 253

Advancing to step 7:
If we divide 1821 by 253, we get 7 and a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 4997.0
If we take 1771 away from 1821, we end up with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 253

Step 8:
506 divided by 253 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 49972.0
If we take 506 away from 506, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
253 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 49972.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 253 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49972.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 49972.0 with a remaining 0.0.
