50742633 ÷ 866 
The aim is to understand the frequency of 866 in 50742633.

Moving on to step 1:
866 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 866

Going ahead to step 2:
When dividing 50 by 866, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 866

Advancing to step 3:
The number 866 fits into 507 0 times, leaving a remainder of 507.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 507 and we're left with 507.
Fetch the next digit (4) from the dividend, attach it to 507 and continue: 5074 / 866

Moving on to step 4:
5074 divided by 866 is 5 with a remainder of 744.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 744 after subtracting 4330 from 5074.
Take the next digit (2) from the dividend and append it to 744, then repeat: 7442 / 866

On to step 5:
7442 divided by 866 is 8 with a remainder of 514.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 514 after subtracting 6928 from 7442.
Include the next digit (6) from the dividend after 514, then repeat: 5146 / 866

Step 6:
5146 divided by 866 is 5 with a remainder of 816.
Record the quotient 5 as the next digit in the result. 
Result so far: 585.0
The remainder is 816 after subtracting 4330 from 5146.
Append the next digit (3) from the dividend to 816 and continue with: 8163 / 866

Moving on to step 7:
If we divide 8163 by 866, we get 9 and a remainder of 369.
Use 9 as the next digit of our solution. 
Result so far: 5859.0
The remainder is 369 after subtracting 7794 from 8163.
Include the next digit (3) from the dividend after 369, then repeat: 3693 / 866

Step 8:
866 goes into 3693 4 times with a remainder of 229.
The number 4 becomes the next digit in our result. 
Result so far: 58594.0
The remainder is 229 after subtracting 3464 from 3693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 9:
2290 divided by 866 is 2 with a remainder of 558.
The number 2 becomes the next digit in our result. 
Result so far: 58594.2
If we take 1732 away from 2290, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 10:
866 goes into 5580 6 times with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 58594.26
If we take 5196 away from 5580, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 11:
3840 divided by 866 is 4 with a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 58594.264
If we take 3464 away from 3840, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 12:
866 goes into 3760 4 times with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 58594.2644
Subtracting 3464 from 3760 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Our division results in 58594.2644 with a remaining 0.00296.
