78999777 divided by 205 
The aim is to understand the frequency of 205 in 78999777.

Let's proceed to step 1:
205 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 205

On to step 2:
78 divided by 205 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 205

Advancing to step 3:
When dividing 789 by 205, we get 3 with a remainder of 174.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 615 from 789 leaves us with 174.
Include the next digit (9) from the dividend after 174, then repeat: 1749 / 205

Going ahead to step 4:
If we divide 1749 by 205, we get 8 and a remainder of 109.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtracting 1640 from 1749 leaves us with 109.
Bring next digit (9) of the dividend behind the 109 and repeat the process: 1099 / 205

Advancing to step 5:
The number 205 fits into 1099 5 times, leaving a remainder of 74.
Put 5 as the next digit of the answer. 
Result so far: 385.0
Subtracting 1025 from 1099 leaves us with 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 205

Moving on to step 6:
205 goes into 747 3 times with a remainder of 132.
Put 3 as the next digit of the answer. 
Result so far: 3853.0
If we subtract 615 from 747, we get 132.
Append the next digit (7) from the dividend to 132 and continue with: 1327 / 205

Going ahead to step 7:
If we divide 1327 by 205, we get 6 and a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 38536.0
Subtract 1230 from 1327 to get 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 205

Advancing to step 8:
205 can be fit into 977 4 times, resulting in a remainder of 157.
Record the quotient 4 as the next digit in the result. 
Result so far: 385364.0
If we take 820 away from 977, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Advancing to step 9:
When dividing 1570 by 205, we get 7 with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 385364.7
Subtracting 1435 from 1570 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
205 goes into 1350 6 times with a remainder of 120.
The next digit of our result is 6. 
Result so far: 385364.76
If we subtract 1230 from 1350, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
205 can be fit into 1200 5 times, resulting in a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 385364.765
Subtract 1025 from 1200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 12:
The number 205 fits into 1750 8 times, leaving a remainder of 110.
The number 8 becomes the next digit in our result. 
Result so far: 385364.7658
Subtracting 1640 from 1750 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 13:
When dividing 1100 by 205, we get 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 385364.76585
The remainder is 75 after subtracting 1025 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
205 goes into 750 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 385364.765853
If we take 615 away from 750, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 15:
If we divide 1350 by 205, we get 6 and a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 385364.7658536
Subtracting 1230 from 1350 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
When dividing 1200 by 205, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 385364.76585365
Subtract 1025 from 1200 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

After the division, we end up with 385364.76585365 and a remainder of 1.75e-07.
