6859625 ÷ 526 
The aim is to understand the frequency of 526 in 6859625.

Moving on to step 1:
If we divide 6 by 526, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 526

Moving on to step 2:
526 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 526

Moving on to step 3:
If we divide 685 by 526, we get 1 and a remainder of 159.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 159 after subtracting 526 from 685.
Take the next digit (9) from the dividend and append it to 159, then repeat: 1599 / 526

On to step 4:
When dividing 1599 by 526, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 21 after subtracting 1578 from 1599.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 526

Step 5:
216 divided by 526 is 0 with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 130.0
Deduct 0 from 216 and we're left with 216.
Take the next digit (2) from the dividend and append it to 216, then repeat: 2162 / 526

Let's proceed to step 6:
The number 526 fits into 2162 4 times, leaving a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 1304.0
The remainder is 58 after subtracting 2104 from 2162.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 526

On to step 7:
If we divide 585 by 526, we get 1 and a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 13041.0
If we take 526 away from 585, we end up 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.

Let's proceed to step 8:
526 can be fit into 590 1 times, resulting in a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 13041.1
Deduct 526 from 590 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
When dividing 640 by 526, we get 1 with a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 13041.11
The remainder is 114 after subtracting 526 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final outcome is 13041.11, with a leftover of 0.114.
