145943 divided by 78 
The aim is to understand the frequency of 78 in 145943.

Moving on to step 1:
If we divide 1 by 78, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 78

On to step 2:
If we divide 14 by 78, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 78

Moving on to step 3:
145 divided by 78 is 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 67 after subtracting 78 from 145.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 78

Moving on to step 4:
679 divided by 78 is 8 with a remainder of 55.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 624 away from 679, we end up with 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 78

Step 5:
78 can be fit into 554 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtract 546 from 554 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 78

Let's proceed to step 6:
The number 78 fits into 83 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1871.0
If we take 78 away from 83, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
78 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1871.0
If we subtract 0 from 50, we 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.

Advancing to step 8:
500 divided by 78 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1871.06
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
320 divided by 78 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1871.064
Subtracting 312 from 320 leaves us 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.

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: 1871.0641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1871.0641
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
The number 78 fits into 200 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1871.064102
If we subtract 156 from 200, we 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.

On to step 13:
78 goes into 440 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1871.0641025
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.

Moving on to step 14:
78 goes into 500 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1871.06410256
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 1871.06410256 with a balance of 3.2e-08.
