686706 ÷ 79 
The aim is to understand the frequency of 79 in 686706.

Going ahead to step 1:
79 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 79

Advancing to step 2:
79 goes into 68 0 times with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 79

Advancing to step 3:
When dividing 686 by 79, we get 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 632 from 686 leaves us with 54.
Include the next digit (7) from the dividend after 54, then repeat: 547 / 79

Let's proceed to step 4:
547 divided by 79 is 6 with a remainder of 73.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 474 from 547 and we're left with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 79

Going ahead to step 5:
79 goes into 730 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 869.0
Deduct 711 from 730 and we're left with 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 79

Going ahead to step 6:
If we divide 196 by 79, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 8692.0
If we take 158 away from 196, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 79, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 8692.4
Subtract 316 from 380 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
The number 79 fits into 640 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8692.48
If we subtract 632 from 640, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
79 can be fit into 80 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 8692.481
If we take 79 away from 80, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 79, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 8692.481
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 79 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 8692.48101
Deduct 79 from 100 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
When dividing 210 by 79, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 8692.481012
Subtract 158 from 210 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
When dividing 520 by 79, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 8692.4810126
If we subtract 474 from 520, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 79, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 8692.48101265
If we take 395 away from 460, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 8692.48101265 with a remainder of 6.5e-08.
