We're dividing 8527861 by 559 
The aim is to understand the frequency of 559 in 8527861.

Moving on to step 1:
If we divide 8 by 559, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 559

Step 2:
559 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (2) from the dividend after 85, then repeat: 852 / 559

Let's proceed to step 3:
559 can be fit into 852 1 times, resulting in a remainder of 293.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 293 after subtracting 559 from 852.
Bring next digit (7) of the dividend behind the 293 and repeat the process: 2937 / 559

Moving on to step 4:
559 can be fit into 2937 5 times, resulting in a remainder of 142.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2795 from 2937, we get 142.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 559

Going ahead to step 5:
559 goes into 1428 2 times with a remainder of 310.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we take 1118 away from 1428, we end up with 310.
Take the next digit (6) from the dividend and append it to 310, then repeat: 3106 / 559

Step 6:
If we divide 3106 by 559, we get 5 and a remainder of 311.
Write down 5 as next digit of the result. 
Result so far: 1525.0
If we take 2795 away from 3106, we end up with 311.
Fetch the next digit (1) from the dividend, attach it to 311 and continue: 3111 / 559

Advancing to step 7:
If we divide 3111 by 559, we get 5 and a remainder of 316.
The next digit of our result is 5. 
Result so far: 15255.0
Subtract 2795 from 3111 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 8:
559 goes into 3160 5 times with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 15255.5
If we subtract 2795 from 3160, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
When dividing 3650 by 559, we get 6 with a remainder of 296.
The next digit of our result is 6. 
Result so far: 15255.56
The remainder is 296 after subtracting 3354 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 10:
If we divide 2960 by 559, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 15255.565
If we take 2795 away from 2960, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 11:
If we divide 1650 by 559, we get 2 and a remainder of 532.
The next digit of our result is 2. 
Result so far: 15255.5652
The remainder is 532 after subtracting 1118 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 12:
If we divide 5320 by 559, we get 9 and a remainder of 289.
The next digit of our result is 9. 
Result so far: 15255.56529
Deduct 5031 from 5320 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 13:
559 goes into 2890 5 times with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 15255.565295
Subtract 2795 from 2890 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 14:
If we divide 950 by 559, we get 1 and a remainder of 391.
Write down 1 as next digit of the result. 
Result so far: 15255.5652951
Subtract 559 from 950 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 15:
3910 divided by 559 is 6 with a remainder of 556.
The next digit of our result is 6. 
Result so far: 15255.56529516
Deduct 3354 from 3910 and we're left with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

The final result is 15255.56529516 with a remainder of 5.56e-07.
