We're dividing 75341 by 78 
The aim is to understand the frequency of 78 in 75341.

On to step 1:
78 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 78

On to step 2:
78 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 78

Step 3:
78 can be fit into 753 9 times, resulting in a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 51 after subtracting 702 from 753.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 78

On to step 4:
78 can be fit into 514 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we take 468 away from 514, we end up with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 78

Advancing to step 5:
The number 78 fits into 461 5 times, leaving a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 965.0
If we subtract 390 from 461, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 6:
710 divided by 78 is 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 965.9
Subtract 702 from 710 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 965.91
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 8:
If we divide 20 by 78, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 965.91
Subtract 0 from 20 to 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.

Step 9:
When dividing 200 by 78, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 965.9102
Subtracting 156 from 200 leaves us with 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 10:
440 divided by 78 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 965.91025
If we subtract 390 from 440, 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.

Going ahead to step 11:
When dividing 500 by 78, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 965.910256
Subtracting 468 from 500 leaves us 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.

Advancing to step 12:
When dividing 320 by 78, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 965.9102564
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.

Advancing to step 13:
When dividing 80 by 78, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 965.91025641
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.

The final result is 965.91025641 with a remainder of 2e-09.
