Let's divide 78636 by 69
The aim is to understand the frequency of 69 in 78636.

Step 1:
7 divided by 69 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 69

Advancing to step 2:
78 divided by 69 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 69 away from 78, we end up with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 69

On to step 3:
96 divided by 69 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 69 from 96 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 69

On to step 4:
69 can be fit into 273 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 113.0
Subtracting 207 from 273 leaves us with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 69

Moving on to step 5:
When dividing 666 by 69, we get 9 with a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 1139.0
The remainder is 45 after subtracting 621 from 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 6:
450 divided by 69 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 1139.6
Subtract 414 from 450 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
69 can be fit into 360 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1139.65
Deduct 345 from 360 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
The number 69 fits into 150 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1139.652
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
69 goes into 120 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1139.6521
If we subtract 69 from 120, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 10:
510 divided by 69 is 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 1139.65217
If we take 483 away from 510, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
The number 69 fits into 270 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 1139.652173
If we take 207 away from 270, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
The number 69 fits into 630 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1139.6521739
Deduct 621 from 630 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
69 can be fit into 90 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1139.65217391
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 1139.65217391, with a leftover of 2.1e-08.
