We're dividing 76940750 by 78 
The aim is to understand the frequency of 78 in 76940750.

Let's proceed to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 78

On to step 2:
When dividing 76 by 78, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (9) from the dividend after 76, then repeat: 769 / 78

On to step 3:
78 goes into 769 9 times with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 702 from 769 leaves us with 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 78

Advancing to step 4:
The number 78 fits into 674 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 624 from 674, we get 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 78

Moving on to step 5:
The number 78 fits into 500 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 986.0
If we subtract 468 from 500, we get 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 78

Going ahead to step 6:
327 divided by 78 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 9864.0
If we subtract 312 from 327, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 78

Let's proceed to step 7:
If we divide 155 by 78, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 98641.0
The remainder is 77 after subtracting 78 from 155.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 78

Going ahead to step 8:
78 goes into 770 9 times with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 986419.0
Subtracting 702 from 770 leaves us 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.

Let's proceed to step 9:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 986419.8
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
560 divided by 78 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 986419.87
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.

Step 11:
78 goes into 140 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 986419.871
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.

Going ahead to step 12:
If we divide 620 by 78, we get 7 and a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 986419.8717
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 13:
78 goes into 740 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 986419.87179
If we subtract 702 from 740, we get 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:
380 divided by 78 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 986419.871794
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.

Let's proceed to step 15:
The number 78 fits into 680 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 986419.8717948
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.

Advancing to step 16:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 986419.87179487
Deduct 546 from 560 and we're left 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.

The final outcome is 986419.87179487, with a leftover of 1.4e-08.
