We look at the division of 25877647 by 534 
The aim is to understand the frequency of 534 in 25877647.

On to step 1:
534 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 534

Advancing to step 2:
534 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 534

Step 3:
If we divide 258 by 534, we get 0 and a remainder of 258.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 258, we get 258.
Grab the next digit (7) from the dividend, add it to 258, then carry on: 2587 / 534

Advancing to step 4:
534 goes into 2587 4 times with a remainder of 451.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2136 from 2587 and we're left with 451.
Append the next digit (7) from the dividend to 451 and continue with: 4517 / 534

Moving on to step 5:
4517 divided by 534 is 8 with a remainder of 245.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 4272 from 4517 and we're left with 245.
Append the next digit (6) from the dividend to 245 and continue with: 2456 / 534

Let's proceed to step 6:
The number 534 fits into 2456 4 times, leaving a remainder of 320.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
If we take 2136 away from 2456, we end up with 320.
Include the next digit (4) from the dividend after 320, then repeat: 3204 / 534

On to step 7:
When dividing 3204 by 534, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 4846.0
If we take 3204 away from 3204, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 534

Step 8:
534 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 48460.0
Subtracting 0 from 7 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
If we divide 70 by 534, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 48460.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 534, we get 1 and a remainder of 166.
Use 1 as the next digit of our solution. 
Result so far: 48460.01
If we subtract 534 from 700, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
The number 534 fits into 1660 3 times, leaving a remainder of 58.
Put 3 as the next digit of the answer. 
Result so far: 48460.013
Deduct 1602 from 1660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
580 divided by 534 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 48460.0131
Deduct 534 from 580 and we're left 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.

Step 13:
534 can be fit into 460 0 times, resulting in a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 48460.0131
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 14:
534 can be fit into 4600 8 times, resulting in a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 48460.013108
The remainder is 328 after subtracting 4272 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 15:
The number 534 fits into 3280 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 48460.0131086
Subtracting 3204 from 3280 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 16:
When dividing 760 by 534, we get 1 with a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 48460.01310861
If we subtract 534 from 760, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 48460.01310861, with a leftover of 2.26e-07.
