We're dividing 169256 by 78 
The aim is to understand the frequency of 78 in 169256.

Advancing to step 1:
The number 78 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 78

Let's proceed to step 2:
78 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 78

Moving on to step 3:
The number 78 fits into 169 2 times, leaving a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 156 from 169 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 78

Moving on to step 4:
If we divide 132 by 78, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 78 from 132 to get 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 78

Advancing to step 5:
545 divided by 78 is 6 with a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 216.0
If we subtract 468 from 545, we get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 78

Step 6:
78 goes into 776 9 times with a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 2169.0
The remainder is 74 after subtracting 702 from 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 2169.9
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 2169.94
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 2169.948
Subtracting 624 from 680 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2169.9487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
140 divided by 78 is 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 2169.94871
If we subtract 78 from 140, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 2169.948717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 2169.9487179
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 2169.94871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 2169.94871794 with a remainder of 6.8e-08.
