We look at the division of 394082 by 79 
The aim is to understand the frequency of 79 in 394082.

Step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 79

Advancing to step 2:
The number 79 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 79

Advancing to step 3:
When dividing 394 by 79, we get 4 with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 316 from 394 leaves us with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 79

On to step 4:
The number 79 fits into 780 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 711 from 780 to get 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 79

On to step 5:
If we divide 698 by 79, we get 8 and a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 498.0
Deduct 632 from 698 and we're left with 66.
Take the next digit (2) from the dividend and append it to 66, then repeat: 662 / 79

On to step 6:
79 goes into 662 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 4988.0
Subtract 632 from 662 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.

Let's proceed to step 7:
If we divide 300 by 79, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 4988.3
Subtract 237 from 300 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
79 can be fit into 630 7 times, resulting in a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 4988.37
If we take 553 away from 630, we end up 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.

Step 9:
When dividing 770 by 79, we get 9 with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 4988.379
If we take 711 away from 770, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
79 can be fit into 590 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 4988.3797
Subtract 553 from 590 to 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 11:
If we divide 370 by 79, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 4988.37974
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.

Going ahead to step 12:
79 goes into 540 6 times with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 4988.379746
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.

Moving on to step 13:
The number 79 fits into 660 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4988.3797468
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
79 can be fit into 280 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 4988.37974683
Subtracting 237 from 280 leaves us 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.

The final outcome is 4988.37974683, with a leftover of 4.3e-08.
