We're dividing 72887774 by 779 
The aim is to understand the frequency of 779 in 72887774.

Advancing to step 1:
The number 779 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 779

Advancing to step 2:
779 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 779

Going ahead to step 3:
If we divide 728 by 779, we get 0 and a remainder of 728.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 728, we get 728.
Append the next digit (8) from the dividend to 728 and continue with: 7288 / 779

Moving on to step 4:
779 goes into 7288 9 times with a remainder of 277.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7011 from 7288, we get 277.
Take the next digit (7) from the dividend and append it to 277, then repeat: 2777 / 779

Step 5:
The number 779 fits into 2777 3 times, leaving a remainder of 440.
The next digit of our result is 3. 
Result so far: 93.0
If we take 2337 away from 2777, we end up with 440.
Fetch the next digit (7) from the dividend, attach it to 440 and continue: 4407 / 779

Advancing to step 6:
When dividing 4407 by 779, we get 5 with a remainder of 512.
Write down 5 as next digit of the result. 
Result so far: 935.0
If we subtract 3895 from 4407, we get 512.
Grab the next digit (7) from the dividend, add it to 512, then carry on: 5127 / 779

Going ahead to step 7:
When dividing 5127 by 779, we get 6 with a remainder of 453.
Use 6 as the next digit of our solution. 
Result so far: 9356.0
If we take 4674 away from 5127, we end up with 453.
Fetch the next digit (4) from the dividend, attach it to 453 and continue: 4534 / 779

On to step 8:
4534 divided by 779 is 5 with a remainder of 639.
Write down 5 as next digit of the result. 
Result so far: 93565.0
If we subtract 3895 from 4534, we get 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 9:
6390 divided by 779 is 8 with a remainder of 158.
Put 8 as the next digit of the answer. 
Result so far: 93565.8
Subtracting 6232 from 6390 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 10:
779 goes into 1580 2 times with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 93565.82
The remainder is 22 after subtracting 1558 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
When dividing 220 by 779, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 93565.82
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
779 can be fit into 2200 2 times, resulting in a remainder of 642.
Record the quotient 2 as the next digit in the result. 
Result so far: 93565.8202
Subtracting 1558 from 2200 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 13:
The number 779 fits into 6420 8 times, leaving a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 93565.82028
Subtract 6232 from 6420 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 14:
When dividing 1880 by 779, we get 2 with a remainder of 322.
The next digit of our result is 2. 
Result so far: 93565.820282
If we take 1558 away from 1880, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 15:
If we divide 3220 by 779, we get 4 and a remainder of 104.
The next digit of our result is 4. 
Result so far: 93565.8202824
Deduct 3116 from 3220 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
The number 779 fits into 1040 1 times, leaving a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 93565.82028241
Deduct 779 from 1040 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

After the division, we end up with 93565.82028241 and a remainder of 2.61e-07.
