We're dividing 79383130 by 686 
The aim is to understand the frequency of 686 in 79383130.

Advancing to step 1:
When dividing 7 by 686, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 686

Advancing to step 2:
When dividing 79 by 686, we get 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (3) from the dividend, attach it to 79 and continue: 793 / 686

Moving on to step 3:
686 can be fit into 793 1 times, resulting in a remainder of 107.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 107 after subtracting 686 from 793.
Grab the next digit (8) from the dividend, add it to 107, then carry on: 1078 / 686

Going ahead to step 4:
If we divide 1078 by 686, we get 1 and a remainder of 392.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 392 after subtracting 686 from 1078.
Take the next digit (3) from the dividend and append it to 392, then repeat: 3923 / 686

Going ahead to step 5:
If we divide 3923 by 686, we get 5 and a remainder of 493.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we take 3430 away from 3923, we end up with 493.
Fetch the next digit (1) from the dividend, attach it to 493 and continue: 4931 / 686

On to step 6:
4931 divided by 686 is 7 with a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 1157.0
If we take 4802 away from 4931, we end up with 129.
Include the next digit (3) from the dividend after 129, then repeat: 1293 / 686

Advancing to step 7:
686 goes into 1293 1 times with a remainder of 607.
Record the quotient 1 as the next digit in the result. 
Result so far: 11571.0
Subtract 686 from 1293 to get 607.
Bring next digit (0) of the dividend behind the 607 and repeat the process: 6070 / 686

Going ahead to step 8:
686 can be fit into 6070 8 times, resulting in a remainder of 582.
Put 8 as the next digit of the answer. 
Result so far: 115718.0
Subtract 5488 from 6070 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 9:
5820 divided by 686 is 8 with a remainder of 332.
Put 8 as the next digit of the answer. 
Result so far: 115718.8
Subtract 5488 from 5820 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 10:
686 can be fit into 3320 4 times, resulting in a remainder of 576.
The next digit of our result is 4. 
Result so far: 115718.84
Subtract 2744 from 3320 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 11:
The number 686 fits into 5760 8 times, leaving a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 115718.848
If we subtract 5488 from 5760, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
When dividing 2720 by 686, we get 3 with a remainder of 662.
The number 3 becomes the next digit in our result. 
Result so far: 115718.8483
If we subtract 2058 from 2720, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 13:
686 goes into 6620 9 times with a remainder of 446.
Put 9 as the next digit of the answer. 
Result so far: 115718.84839
Subtracting 6174 from 6620 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 14:
686 can be fit into 4460 6 times, resulting in a remainder of 344.
The number 6 becomes the next digit in our result. 
Result so far: 115718.848396
The remainder is 344 after subtracting 4116 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 15:
686 goes into 3440 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 115718.8483965
The remainder is 10 after subtracting 3430 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
When dividing 100 by 686, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 115718.8483965
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 115718.8483965 and a remainder of 1e-07.
