751739 divided by 78 
The aim is to understand the frequency of 78 in 751739.

Let's proceed to step 1:
The number 78 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 78

On to step 2:
When dividing 75 by 78, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 78

Going ahead to step 3:
The number 78 fits into 751 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 702 from 751, we get 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 78

Step 4:
497 divided by 78 is 6 with a remainder of 29.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 29 after subtracting 468 from 497.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 78

Moving on to step 5:
78 can be fit into 293 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 963.0
Deduct 234 from 293 and we're left with 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 78

Going ahead to step 6:
When dividing 599 by 78, we get 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 9637.0
Subtract 546 from 599 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
The number 78 fits into 530 6 times, leaving a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 9637.6
If we take 468 away from 530, we end up with 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 8:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 9637.67
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 9:
740 divided by 78 is 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9637.679
Subtract 702 from 740 to 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.

Moving on to step 10:
380 divided by 78 is 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 9637.6794
If we subtract 312 from 380, we 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.

Going ahead to step 11:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 9637.67948
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.

Moving on to step 12:
78 goes into 560 7 times with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 9637.679487
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.

Let's proceed to step 13:
If we divide 140 by 78, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 9637.6794871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 9637.67948717
Subtract 546 from 620 to 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.

The final outcome is 9637.67948717, with a leftover of 7.4e-08.
