139488 ÷ 79 
The aim is to understand the frequency of 79 in 139488.

Moving on to step 1:
79 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 79

Advancing to step 2:
If we divide 13 by 79, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 79

On to step 3:
79 can be fit into 139 1 times, resulting in a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 79 from 139 and we're left with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 79

On to step 4:
604 divided by 79 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 51 after subtracting 553 from 604.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 79

Advancing to step 5:
If we divide 518 by 79, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 176.0
If we take 474 away from 518, we end up with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 79

Moving on to step 6:
448 divided by 79 is 5 with a remainder of 53.
The next digit of our result is 5. 
Result so far: 1765.0
Deduct 395 from 448 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
530 divided by 79 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 1765.6
The remainder is 56 after subtracting 474 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
When dividing 560 by 79, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1765.67
Subtract 553 from 560 to get 7.
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 9:
If we divide 70 by 79, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1765.67
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
79 can be fit into 700 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 1765.6708
Subtracting 632 from 700 leaves us 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.

Let's proceed to step 11:
680 divided by 79 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1765.67088
The remainder is 48 after subtracting 632 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 1765.67088 and a remainder of 4.8e-05.
