We look at the division of 8650813 by 679 
The aim is to understand the frequency of 679 in 8650813.

Moving on to step 1:
The number 679 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 679

Step 2:
When dividing 86 by 679, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 679

Step 3:
679 goes into 865 1 times with a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 679 from 865 leaves us with 186.
Fetch the next digit (0) from the dividend, attach it to 186 and continue: 1860 / 679

Step 4:
The number 679 fits into 1860 2 times, leaving a remainder of 502.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1358 from 1860 and we're left with 502.
Grab the next digit (8) from the dividend, add it to 502, then carry on: 5028 / 679

Let's proceed to step 5:
679 goes into 5028 7 times with a remainder of 275.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we subtract 4753 from 5028, we get 275.
Bring next digit (1) of the dividend behind the 275 and repeat the process: 2751 / 679

Step 6:
The number 679 fits into 2751 4 times, leaving a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 1274.0
If we subtract 2716 from 2751, we get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 679

On to step 7:
353 divided by 679 is 0 with a remainder of 353.
Put 0 as the next digit of the answer. 
Result so far: 12740.0
If we subtract 0 from 353, we get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 8:
679 goes into 3530 5 times with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 12740.5
If we subtract 3395 from 3530, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
If we divide 1350 by 679, we get 1 and a remainder of 671.
Put 1 as the next digit of the answer. 
Result so far: 12740.51
If we subtract 679 from 1350, we get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

On to step 10:
6710 divided by 679 is 9 with a remainder of 599.
Put 9 as the next digit of the answer. 
Result so far: 12740.519
If we take 6111 away from 6710, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 11:
If we divide 5990 by 679, we get 8 and a remainder of 558.
Use 8 as the next digit of our solution. 
Result so far: 12740.5198
If we take 5432 away from 5990, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 12:
5580 divided by 679 is 8 with a remainder of 148.
The next digit of our result is 8. 
Result so far: 12740.51988
The remainder is 148 after subtracting 5432 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 12740.51988 and a remainder of 0.000148.
