We're dividing 515114 by 78 
The aim is to understand the frequency of 78 in 515114.

Going ahead to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 78

Moving on to step 2:
The number 78 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 78

Let's proceed to step 3:
78 can be fit into 515 6 times, resulting in a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 468 from 515, we get 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 78

Step 4:
If we divide 471 by 78, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Deduct 468 from 471 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

Advancing to step 5:
31 divided by 78 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 660.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 78

Step 6:
314 divided by 78 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 6604.0
The remainder is 2 after subtracting 312 from 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6604.0
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.

Moving on to step 8:
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: 6604.02
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.

Advancing to step 9:
78 goes into 440 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6604.025
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.

Moving on to step 10:
When dividing 500 by 78, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 6604.0256
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.

Going ahead to step 11:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 6604.02564
If we subtract 312 from 320, we 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.

Advancing to step 12:
78 can be fit into 80 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 6604.025641
Subtract 78 from 80 to 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.

Going ahead to step 13:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 6604.025641
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 14:
If we divide 200 by 78, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 6604.02564102
Deduct 156 from 200 and we're left 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.

After the division, we end up with 6604.02564102 and a remainder of 4.4e-08.
