We divide 786980 by 79
The aim is to understand the frequency of 79 in 786980.

Moving on to step 1:
If we divide 7 by 79, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 79

Moving on to step 2:
When dividing 78 by 79, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 79

Step 3:
When dividing 786 by 79, we get 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 711 from 786 and we're left with 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 79

Step 4:
If we divide 759 by 79, we get 9 and a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 99.0
If we take 711 away from 759, we end up with 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 79

Advancing to step 5:
488 divided by 79 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 996.0
The remainder is 14 after subtracting 474 from 488.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 79

Let's proceed to step 6:
79 can be fit into 140 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 9961.0
The remainder is 61 after subtracting 79 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
79 can be fit into 610 7 times, resulting in a remainder of 57.
The next digit of our result is 7. 
Result so far: 9961.7
Subtract 553 from 610 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 8:
79 goes into 570 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 9961.77
Deduct 553 from 570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 9961.77 with a balance of 0.017.
