317699 ÷ 78 
The aim is to understand the frequency of 78 in 317699.

Let's proceed to step 1:
When dividing 3 by 78, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 78

Advancing to step 2:
The number 78 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 78

Advancing to step 3:
78 can be fit into 317 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 312 away from 317, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 78

Going ahead to step 4:
If we divide 56 by 78, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 56 and we're left with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 78

Let's proceed to step 5:
If we divide 569 by 78, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Deduct 546 from 569 and we're left with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 78

On to step 6:
78 can be fit into 239 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 4073.0
The remainder is 5 after subtracting 234 from 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 78 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4073.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4073.06
If we subtract 468 from 500, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4073.064
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 78, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 4073.0641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
When dividing 20 by 78, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4073.0641
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 78, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 4073.064102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 4073.0641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 78, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 4073.06410256
Subtract 468 from 500 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 4073.06410256 with a balance of 3.2e-08.
