We're dividing 19481966 by 253 
The aim is to understand the frequency of 253 in 19481966.

Let's proceed to step 1:
When dividing 1 by 253, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 253

Going ahead to step 2:
253 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 253

On to step 3:
When dividing 194 by 253, we get 0 with a remainder of 194.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 194 leaves us with 194.
Bring next digit (8) of the dividend behind the 194 and repeat the process: 1948 / 253

Advancing to step 4:
The number 253 fits into 1948 7 times, leaving a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1771 from 1948 and we're left with 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 253

Advancing to step 5:
253 can be fit into 1771 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 1771 from 1771, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 253

Going ahead to step 6:
The number 253 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 770.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 253

Going ahead to step 7:
The number 253 fits into 96 0 times, leaving a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 7700.0
Deduct 0 from 96 and we're left with 96.
Fetch the next digit (6) from the dividend, attach it to 96 and continue: 966 / 253

Let's proceed to step 8:
The number 253 fits into 966 3 times, leaving a remainder of 207.
Use 3 as the next digit of our solution. 
Result so far: 77003.0
If we take 759 away from 966, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Advancing to step 9:
2070 divided by 253 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 77003.8
The remainder is 46 after subtracting 2024 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
When dividing 460 by 253, we get 1 with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 77003.81
If we take 253 away from 460, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 11:
The number 253 fits into 2070 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 77003.818
The remainder is 46 after subtracting 2024 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
253 goes into 460 1 times with a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 77003.8181
The remainder is 207 after subtracting 253 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 13:
253 goes into 2070 8 times with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 77003.81818
If we subtract 2024 from 2070, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
If we divide 460 by 253, we get 1 and a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 77003.818181
The remainder is 207 after subtracting 253 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 15:
The number 253 fits into 2070 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 77003.8181818
If we take 2024 away from 2070, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 16:
If we divide 460 by 253, we get 1 and a remainder of 207.
Put 1 as the next digit of the answer. 
Result so far: 77003.81818181
If we subtract 253 from 460, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

After the division, we end up with 77003.81818181 and a remainder of 2.07e-07.
