We're dividing 42168869 by 772 
The aim is to understand the frequency of 772 in 42168869.

Step 1:
4 divided by 772 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 772

Let's proceed to step 2:
If we divide 42 by 772, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 772

On to step 3:
772 goes into 421 0 times with a remainder of 421.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 421 leaves us with 421.
Take the next digit (6) from the dividend and append it to 421, then repeat: 4216 / 772

Step 4:
The number 772 fits into 4216 5 times, leaving a remainder of 356.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 3860 from 4216 leaves us with 356.
Fetch the next digit (8) from the dividend, attach it to 356 and continue: 3568 / 772

On to step 5:
772 goes into 3568 4 times with a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Deduct 3088 from 3568 and we're left with 480.
Append the next digit (8) from the dividend to 480 and continue with: 4808 / 772

Advancing to step 6:
If we divide 4808 by 772, we get 6 and a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 546.0
Deduct 4632 from 4808 and we're left with 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 772

On to step 7:
If we divide 1766 by 772, we get 2 and a remainder of 222.
Record the quotient 2 as the next digit in the result. 
Result so far: 5462.0
If we subtract 1544 from 1766, we get 222.
Append the next digit (9) from the dividend to 222 and continue with: 2229 / 772

Moving on to step 8:
The number 772 fits into 2229 2 times, leaving a remainder of 685.
The next digit of our result is 2. 
Result so far: 54622.0
If we take 1544 away from 2229, we end up with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Step 9:
772 goes into 6850 8 times with a remainder of 674.
Use 8 as the next digit of our solution. 
Result so far: 54622.8
Subtracting 6176 from 6850 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 10:
When dividing 6740 by 772, we get 8 with a remainder of 564.
Use 8 as the next digit of our solution. 
Result so far: 54622.88
If we take 6176 away from 6740, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

After the division, we end up with 54622.88 and a remainder of 0.564.
