51667455 ÷ 253 
The aim is to understand the frequency of 253 in 51667455.

On to step 1:
When dividing 5 by 253, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 253

Going ahead to step 2:
253 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 253

Advancing to step 3:
When dividing 516 by 253, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 506 from 516 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 253

On to step 4:
When dividing 106 by 253, we get 0 with a remainder of 106.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 106, we end up with 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 253

Moving on to step 5:
The number 253 fits into 1067 4 times, leaving a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtract 1012 from 1067 to get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 253

Step 6:
The number 253 fits into 554 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 2042.0
The remainder is 48 after subtracting 506 from 554.
Take the next digit (5) from the dividend and append it to 48, then repeat: 485 / 253

Let's proceed to step 7:
When dividing 485 by 253, we get 1 with a remainder of 232.
Put 1 as the next digit of the answer. 
Result so far: 20421.0
The remainder is 232 after subtracting 253 from 485.
Append the next digit (5) from the dividend to 232 and continue with: 2325 / 253

Going ahead to step 8:
253 goes into 2325 9 times with a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 204219.0
Subtract 2277 from 2325 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 253, we get 1 with a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 204219.1
Subtracting 253 from 480 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 10:
If we divide 2270 by 253, we get 8 and a remainder of 246.
The next digit of our result is 8. 
Result so far: 204219.18
Deduct 2024 from 2270 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 11:
If we divide 2460 by 253, we get 9 and a remainder of 183.
The next digit of our result is 9. 
Result so far: 204219.189
If we subtract 2277 from 2460, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 12:
The number 253 fits into 1830 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 204219.1897
The remainder is 59 after subtracting 1771 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 13:
253 can be fit into 590 2 times, resulting in a remainder of 84.
The next digit of our result is 2. 
Result so far: 204219.18972
Deduct 506 from 590 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
If we divide 840 by 253, we get 3 and a remainder of 81.
Record the quotient 3 as the next digit in the result. 
Result so far: 204219.189723
Subtract 759 from 840 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 15:
253 goes into 810 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 204219.1897233
Deduct 759 from 810 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 204219.1897233 with a remainder of 5.1e-07.
