We look at the division of 51547882 by 281 
The aim is to understand the frequency of 281 in 51547882.

Going ahead to step 1:
281 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 281

Let's proceed to step 2:
281 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 281

Moving on to step 3:
When dividing 515 by 281, we get 1 with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 281 from 515 to get 234.
Fetch the next digit (4) from the dividend, attach it to 234 and continue: 2344 / 281

Moving on to step 4:
If we divide 2344 by 281, we get 8 and a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 2248 away from 2344, we end up with 96.
Fetch the next digit (7) from the dividend, attach it to 96 and continue: 967 / 281

Let's proceed to step 5:
281 can be fit into 967 3 times, resulting in a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 183.0
Subtracting 843 from 967 leaves us with 124.
Fetch the next digit (8) from the dividend, attach it to 124 and continue: 1248 / 281

Step 6:
1248 divided by 281 is 4 with a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 1834.0
Subtract 1124 from 1248 to get 124.
Take the next digit (8) from the dividend and append it to 124, then repeat: 1248 / 281

On to step 7:
When dividing 1248 by 281, we get 4 with a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 18344.0
If we subtract 1124 from 1248, we get 124.
Grab the next digit (2) from the dividend, add it to 124, then carry on: 1242 / 281

Moving on to step 8:
When dividing 1242 by 281, we get 4 with a remainder of 118.
Write down 4 as next digit of the result. 
Result so far: 183444.0
If we take 1124 away from 1242, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 9:
1180 divided by 281 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 183444.4
Subtract 1124 from 1180 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
281 goes into 560 1 times with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 183444.41
If we take 281 away from 560, we end up with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Let's proceed to step 11:
When dividing 2790 by 281, we get 9 with a remainder of 261.
Record the quotient 9 as the next digit in the result. 
Result so far: 183444.419
The remainder is 261 after subtracting 2529 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 12:
When dividing 2610 by 281, we get 9 with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 183444.4199
If we take 2529 away from 2610, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final result is 183444.4199 with a remainder of 0.00081.
