Let's divide 684176 by 78
The aim is to understand the frequency of 78 in 684176.

On to step 1:
78 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 78

Moving on to step 2:
78 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 78

Moving on to step 3:
78 goes into 684 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 624 from 684 and we're left with 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 78

Advancing to step 4:
When dividing 601 by 78, we get 7 with a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 546 from 601 leaves us with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 78

Let's proceed to step 5:
557 divided by 78 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 877.0
Subtract 546 from 557 to get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 78

Let's proceed to step 6:
The number 78 fits into 116 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 8771.0
The remainder is 38 after subtracting 78 from 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 8771.4
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.

Going ahead to step 8:
78 can be fit into 680 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8771.48
If we take 624 away from 680, we end up 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.
The next digit of our result is 7. 
Result so far: 8771.487
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.

Step 10:
140 divided by 78 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 8771.4871
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.

Advancing to step 11:
78 goes into 620 7 times with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 8771.48717
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.

Moving on to step 12:
If we divide 740 by 78, we get 9 and a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 8771.487179
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.

Advancing to step 13:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 8771.4871794
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.

Going ahead to step 14:
680 divided by 78 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8771.48717948
If we take 624 away from 680, we end up 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.

In conclusion, the division gives 8771.48717948 with a balance of 5.6e-08.
