We're dividing 80319725 by 679 
The aim is to understand the frequency of 679 in 80319725.

Step 1:
If we divide 8 by 679, we get 0 and 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.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 679

On to step 2:
The number 679 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 679

Step 3:
If we divide 803 by 679, we get 1 and a remainder of 124.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 679 away from 803, we end up with 124.
Bring next digit (1) of the dividend behind the 124 and repeat the process: 1241 / 679

Advancing to step 4:
The number 679 fits into 1241 1 times, leaving a remainder of 562.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 679 from 1241 to get 562.
Include the next digit (9) from the dividend after 562, then repeat: 5629 / 679

On to step 5:
The number 679 fits into 5629 8 times, leaving a remainder of 197.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 5432 from 5629 and we're left with 197.
Take the next digit (7) from the dividend and append it to 197, then repeat: 1977 / 679

Let's proceed to step 6:
1977 divided by 679 is 2 with a remainder of 619.
The next digit of our result is 2. 
Result so far: 1182.0
Deduct 1358 from 1977 and we're left with 619.
Include the next digit (2) from the dividend after 619, then repeat: 6192 / 679

Going ahead to step 7:
The number 679 fits into 6192 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 11829.0
Subtract 6111 from 6192 to get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 679

Going ahead to step 8:
If we divide 815 by 679, we get 1 and a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 118291.0
The remainder is 136 after subtracting 679 from 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
If we divide 1360 by 679, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 118291.2
Subtract 1358 from 1360 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
679 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 118291.2
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 679, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 118291.2
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 118291.2, and the remainder is 0.02.
