We look at the division of 42634238 by 526 
The aim is to understand the frequency of 526 in 42634238.

Advancing to step 1:
4 divided by 526 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 526

Advancing to step 2:
If we divide 42 by 526, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 526

Step 3:
The number 526 fits into 426 0 times, leaving a remainder of 426.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 426 and we're left with 426.
Take the next digit (3) from the dividend and append it to 426, then repeat: 4263 / 526

Let's proceed to step 4:
The number 526 fits into 4263 8 times, leaving a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 4208 from 4263, we get 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 526

Step 5:
554 divided by 526 is 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 526 from 554, we get 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 526

Step 6:
526 goes into 282 0 times with a remainder of 282.
The next digit of our result is 0. 
Result so far: 810.0
The remainder is 282 after subtracting 0 from 282.
Include the next digit (3) from the dividend after 282, then repeat: 2823 / 526

Step 7:
When dividing 2823 by 526, we get 5 with a remainder of 193.
The number 5 becomes the next digit in our result. 
Result so far: 8105.0
Subtracting 2630 from 2823 leaves us with 193.
Include the next digit (8) from the dividend after 193, then repeat: 1938 / 526

Step 8:
If we divide 1938 by 526, we get 3 and a remainder of 360.
The number 3 becomes the next digit in our result. 
Result so far: 81053.0
Subtracting 1578 from 1938 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
3600 divided by 526 is 6 with a remainder of 444.
The next digit of our result is 6. 
Result so far: 81053.6
Deduct 3156 from 3600 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 10:
4440 divided by 526 is 8 with a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 81053.68
The remainder is 232 after subtracting 4208 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
When dividing 2320 by 526, we get 4 with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 81053.684
If we take 2104 away from 2320, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 12:
If we divide 2160 by 526, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 81053.6844
If we take 2104 away from 2160, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 81053.6844, with a leftover of 0.00056.
