We look at the division of 75750228 by 281 
The aim is to understand the frequency of 281 in 75750228.

Step 1:
If we divide 7 by 281, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 281

Advancing to step 2:
When dividing 75 by 281, we get 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 281

Moving on to step 3:
281 can be fit into 757 2 times, resulting in a remainder of 195.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 562 from 757 to get 195.
Bring next digit (5) of the dividend behind the 195 and repeat the process: 1955 / 281

Let's proceed to step 4:
When dividing 1955 by 281, we get 6 with a remainder of 269.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 1686 away from 1955, we end up with 269.
Take the next digit (0) from the dividend and append it to 269, then repeat: 2690 / 281

Step 5:
If we divide 2690 by 281, we get 9 and a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
The remainder is 161 after subtracting 2529 from 2690.
Bring next digit (2) of the dividend behind the 161 and repeat the process: 1612 / 281

Advancing to step 6:
The number 281 fits into 1612 5 times, leaving a remainder of 207.
The next digit of our result is 5. 
Result so far: 2695.0
The remainder is 207 after subtracting 1405 from 1612.
Bring next digit (2) of the dividend behind the 207 and repeat the process: 2072 / 281

Advancing to step 7:
2072 divided by 281 is 7 with a remainder of 105.
Put 7 as the next digit of the answer. 
Result so far: 26957.0
Deduct 1967 from 2072 and we're left with 105.
Append the next digit (8) from the dividend to 105 and continue with: 1058 / 281

Moving on to step 8:
1058 divided by 281 is 3 with a remainder of 215.
Use 3 as the next digit of our solution. 
Result so far: 269573.0
Subtracting 843 from 1058 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 9:
2150 divided by 281 is 7 with a remainder of 183.
The next digit of our result is 7. 
Result so far: 269573.7
The remainder is 183 after subtracting 1967 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 10:
281 goes into 1830 6 times with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 269573.76
Subtract 1686 from 1830 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
281 goes into 1440 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 269573.765
If we subtract 1405 from 1440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
281 goes into 350 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 269573.7651
Deduct 281 from 350 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
690 divided by 281 is 2 with a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 269573.76512
The remainder is 128 after subtracting 562 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 14:
281 goes into 1280 4 times with a remainder of 156.
The next digit of our result is 4. 
Result so far: 269573.765124
Subtract 1124 from 1280 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 15:
281 can be fit into 1560 5 times, resulting in a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 269573.7651245
Subtract 1405 from 1560 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 16:
When dividing 1550 by 281, we get 5 with a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 269573.76512455
The remainder is 145 after subtracting 1405 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

The final result is 269573.76512455 with a remainder of 1.45e-07.
