We're dividing 54409579 by 679 
The aim is to understand the frequency of 679 in 54409579.

Step 1:
If we divide 5 by 679, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 679

Going ahead to step 2:
679 goes into 54 0 times with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 679

Let's proceed to step 3:
If we divide 544 by 679, we get 0 and a remainder of 544.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 544, we end up with 544.
Include the next digit (0) from the dividend after 544, then repeat: 5440 / 679

Advancing to step 4:
The number 679 fits into 5440 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 5432 from 5440 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 679

Going ahead to step 5:
The number 679 fits into 89 0 times, leaving a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 80.0
Deduct 0 from 89 and we're left with 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 679

Let's proceed to step 6:
If we divide 895 by 679, we get 1 and a remainder of 216.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
If we take 679 away from 895, we end up with 216.
Grab the next digit (7) from the dividend, add it to 216, then carry on: 2167 / 679

Let's proceed to step 7:
If we divide 2167 by 679, we get 3 and a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 8013.0
Subtract 2037 from 2167 to get 130.
Fetch the next digit (9) from the dividend, attach it to 130 and continue: 1309 / 679

Advancing to step 8:
679 can be fit into 1309 1 times, resulting in a remainder of 630.
Put 1 as the next digit of the answer. 
Result so far: 80131.0
Subtract 679 from 1309 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 9:
6300 divided by 679 is 9 with a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 80131.9
If we subtract 6111 from 6300, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 10:
679 goes into 1890 2 times with a remainder of 532.
Use 2 as the next digit of our solution. 
Result so far: 80131.92
The remainder is 532 after subtracting 1358 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 11:
The number 679 fits into 5320 7 times, leaving a remainder of 567.
Write down 7 as next digit of the result. 
Result so far: 80131.927
If we take 4753 away from 5320, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 12:
When dividing 5670 by 679, we get 8 with a remainder of 238.
Put 8 as the next digit of the answer. 
Result so far: 80131.9278
Deduct 5432 from 5670 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 13:
The number 679 fits into 2380 3 times, leaving a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 80131.92783
If we subtract 2037 from 2380, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Let's proceed to step 14:
The number 679 fits into 3430 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 80131.927835
The remainder is 35 after subtracting 3395 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
679 goes into 350 0 times with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 80131.927835
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 16:
The number 679 fits into 3500 5 times, leaving a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 80131.92783505
If we subtract 3395 from 3500, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 80131.92783505, and the remainder is 1.05e-07.
