We divide 680140 by 79
The aim is to understand the frequency of 79 in 680140.

On to step 1:
When dividing 6 by 79, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 79

Moving on to step 2:
79 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 79

On to step 3:
The number 79 fits into 680 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 632 from 680, we get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 79

Moving on to step 4:
The number 79 fits into 481 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 474 from 481 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 79

Let's proceed to step 5:
If we divide 74 by 79, we get 0 and a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 860.0
The remainder is 74 after subtracting 0 from 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 79

Let's proceed to step 6:
79 goes into 740 9 times with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 8609.0
The remainder is 29 after subtracting 711 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
79 goes into 290 3 times with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 8609.3
If we subtract 237 from 290, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 8:
If we divide 530 by 79, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 8609.36
Deduct 474 from 530 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
If we divide 560 by 79, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 8609.367
The remainder is 7 after subtracting 553 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
The number 79 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 8609.367
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
If we divide 700 by 79, we get 8 and a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 8609.36708
If we take 632 away from 700, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
79 goes into 680 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 8609.367088
If we take 632 away from 680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 8609.367088 with a remaining 4.8e-06.
