We look at the division of 599611 by 78 
The aim is to understand the frequency of 78 in 599611.

Going ahead to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 78

Step 2:
When dividing 59 by 78, we get 0 with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 78

Going ahead to step 3:
When dividing 599 by 78, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 53 after subtracting 546 from 599.
Include the next digit (6) from the dividend after 53, then repeat: 536 / 78

Advancing to step 4:
78 goes into 536 6 times with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 468 from 536, we get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 78

Let's proceed to step 5:
If we divide 681 by 78, we get 8 and a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 768.0
The remainder is 57 after subtracting 624 from 681.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 78

Step 6:
78 can be fit into 571 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 7687.0
If we take 546 away from 571, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
The number 78 fits into 250 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 7687.3
If we take 234 away from 250, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 7687.32
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7687.32
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
78 can be fit into 400 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7687.3205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 7687.32051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 7687.320512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
640 divided by 78 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 7687.3205128
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 78, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7687.32051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 7687.32051282 with a balance of 4e-09.
