Let's divide 108302 by 78
The aim is to understand the frequency of 78 in 108302.

On to step 1:
When dividing 1 by 78, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 78

On to step 2:
78 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 78

Step 3:
The number 78 fits into 108 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 30 after subtracting 78 from 108.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 78

Step 4:
78 goes into 303 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 234 from 303 leaves us with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 78

Advancing to step 5:
78 goes into 690 8 times with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 624 from 690 to get 66.
Bring next digit (2) of the dividend behind the 66 and repeat the process: 662 / 78

Advancing to step 6:
The number 78 fits into 662 8 times, leaving a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 1388.0
If we take 624 away from 662, we end up 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 7:
If we divide 380 by 78, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 1388.4
Deduct 312 from 380 and we're left 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.

Step 8:
680 divided by 78 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 1388.48
Deduct 624 from 680 and we're left 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.

On to step 9:
560 divided by 78 is 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 1388.487
Subtracting 546 from 560 leaves us with 14.
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 10:
78 can be fit into 140 1 times, resulting in a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1388.4871
Subtract 78 from 140 to 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.

Let's proceed to step 11:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 1388.48717
If we subtract 546 from 620, we get 74.
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 12:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1388.487179
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.

Going ahead to step 13:
78 goes into 380 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 1388.4871794
Deduct 312 from 380 and we're left 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.

Step 14:
680 divided by 78 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 1388.48717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 1388.48717948 with a remaining 5.6e-08.
