We look at the division of 886673 by 78 
The aim is to understand the frequency of 78 in 886673.

Let's proceed to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 78

Let's proceed to step 2:
The number 78 fits into 88 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 78 from 88 and we're left with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 78

Moving on to step 3:
The number 78 fits into 106 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 28 after subtracting 78 from 106.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 78

Going ahead to step 4:
When dividing 286 by 78, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 234 away from 286, we end up with 52.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 78

Step 5:
527 divided by 78 is 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 1136.0
If we subtract 468 from 527, we get 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 78

Going ahead to step 6:
The number 78 fits into 593 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 11367.0
Subtract 546 from 593 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
78 goes into 470 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 11367.6
If we subtract 468 from 470, 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.

Advancing to step 8:
If we divide 20 by 78, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11367.6
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:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11367.602
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 11367.6025
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:
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: 11367.60256
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.

Going ahead to step 12:
When dividing 320 by 78, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 11367.602564
Deduct 312 from 320 and we're left 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.

Let's proceed to step 13:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 11367.6025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
78 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11367.6025641
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.

The final outcome is 11367.6025641, with a leftover of 2e-08.
