765178 divided by 79 
The aim is to understand the frequency of 79 in 765178.

Moving on to step 1:
If we divide 7 by 79, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 79

Going ahead to step 2:
The number 79 fits into 76 0 times, leaving a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 79

On to step 3:
765 divided by 79 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 711 from 765 leaves us with 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 79

Let's proceed to step 4:
79 can be fit into 541 6 times, resulting in a remainder of 67.
The next digit of our result is 6. 
Result so far: 96.0
Subtracting 474 from 541 leaves us with 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 79

Step 5:
677 divided by 79 is 8 with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 968.0
Subtracting 632 from 677 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 79

Going ahead to step 6:
458 divided by 79 is 5 with a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 9685.0
Deduct 395 from 458 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 79, we get 7 with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 9685.7
Subtracting 553 from 630 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
79 can be fit into 770 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 9685.79
The remainder is 59 after subtracting 711 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 9:
If we divide 590 by 79, we get 7 and a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 9685.797
If we subtract 553 from 590, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
When dividing 370 by 79, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 9685.7974
Subtracting 316 from 370 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
If we divide 540 by 79, we get 6 and a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 9685.79746
Deduct 474 from 540 and we're left 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.

Step 12:
79 can be fit into 660 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 9685.797468
The remainder is 28 after subtracting 632 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
79 goes into 280 3 times with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 9685.7974683
Deduct 237 from 280 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 14:
If we divide 430 by 79, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 9685.79746835
Deduct 395 from 430 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 9685.79746835, with a leftover of 3.5e-08.
