69719688 ÷ 78 
The aim is to understand the frequency of 78 in 69719688.

On to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 78

Moving on to step 2:
When dividing 69 by 78, we get 0 with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 78

Let's proceed to step 3:
78 can be fit into 697 8 times, resulting in a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 73 after subtracting 624 from 697.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 78

Step 4:
78 goes into 731 9 times with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 702 from 731 leaves us with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 78

On to step 5:
When dividing 299 by 78, we get 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 893.0
Subtracting 234 from 299 leaves us with 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 78

Let's proceed to step 6:
The number 78 fits into 656 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 8938.0
Subtract 624 from 656 to get 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 78

Moving on to step 7:
78 goes into 328 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 89384.0
Subtracting 312 from 328 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 78

Going ahead to step 8:
The number 78 fits into 168 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 893842.0
The remainder is 12 after subtracting 156 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 893842.1
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 893842.15
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 893842.153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 893842.1538
If we subtract 624 from 660, we 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.

Going ahead to step 13:
If we divide 360 by 78, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 893842.15384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
78 goes into 480 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 893842.153846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 15:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 893842.1538461
Subtracting 78 from 120 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 16:
When dividing 420 by 78, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 893842.15384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 893842.15384615 with a balance of 3e-08.
