We look at the division of 50067937 by 253 
The aim is to understand the frequency of 253 in 50067937.

On to step 1:
If we divide 5 by 253, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 253

On to step 2:
253 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 253

Let's proceed to step 3:
If we divide 500 by 253, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 253 from 500 to get 247.
Take the next digit (6) from the dividend and append it to 247, then repeat: 2476 / 253

On to step 4:
253 can be fit into 2476 9 times, resulting in a remainder of 199.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 2277 from 2476 leaves us with 199.
Grab the next digit (7) from the dividend, add it to 199, then carry on: 1997 / 253

On to step 5:
253 goes into 1997 7 times with a remainder of 226.
The next digit of our result is 7. 
Result so far: 197.0
Subtract 1771 from 1997 to get 226.
Fetch the next digit (9) from the dividend, attach it to 226 and continue: 2269 / 253

Moving on to step 6:
When dividing 2269 by 253, we get 8 with a remainder of 245.
Put 8 as the next digit of the answer. 
Result so far: 1978.0
Subtract 2024 from 2269 to get 245.
Include the next digit (3) from the dividend after 245, then repeat: 2453 / 253

Going ahead to step 7:
2453 divided by 253 is 9 with a remainder of 176.
The next digit of our result is 9. 
Result so far: 19789.0
If we subtract 2277 from 2453, we get 176.
Include the next digit (7) from the dividend after 176, then repeat: 1767 / 253

Moving on to step 8:
When dividing 1767 by 253, we get 6 with a remainder of 249.
Use 6 as the next digit of our solution. 
Result so far: 197896.0
Subtract 1518 from 1767 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
2490 divided by 253 is 9 with a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 197896.9
Subtract 2277 from 2490 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 10:
253 can be fit into 2130 8 times, resulting in a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 197896.98
Subtract 2024 from 2130 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
1060 divided by 253 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 197896.984
The remainder is 48 after subtracting 1012 from 1060.
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 12:
480 divided by 253 is 1 with a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 197896.9841
Subtract 253 from 480 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 13:
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: 197896.98418
If we take 2024 away from 2270, we end up 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.

On to step 14:
253 can be fit into 2460 9 times, resulting in a remainder of 183.
The next digit of our result is 9. 
Result so far: 197896.984189
Subtract 2277 from 2460 to 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.

Step 15:
253 can be fit into 1830 7 times, resulting in a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 197896.9841897
Subtracting 1771 from 1830 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 16:
The number 253 fits into 590 2 times, leaving a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 197896.98418972
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.

The quotient of the division is 197896.98418972, and the remainder is 8.4e-08.
