139650 divided by 79 
The aim is to understand the frequency of 79 in 139650.

Going ahead to step 1:
1 divided by 79 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 79

Going ahead to step 2:
When dividing 13 by 79, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 79

On to step 3:
79 goes into 139 1 times with 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.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 79

Step 4:
79 goes into 606 7 times with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 553 from 606, we get 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 79

Moving on to step 5:
When dividing 535 by 79, we get 6 with a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 176.0
Deduct 474 from 535 and we're left with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 79

Moving on to step 6:
610 divided by 79 is 7 with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 1767.0
If we subtract 553 from 610, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
79 goes into 570 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 1767.7
Deduct 553 from 570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
When dividing 170 by 79, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 1767.72
Deduct 158 from 170 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 79, we get 1 with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1767.721
Subtract 79 from 120 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
If we divide 410 by 79, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 1767.7215
If we take 395 away from 410, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
79 can be fit into 150 1 times, resulting in a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1767.72151
If we subtract 79 from 150, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
When dividing 710 by 79, we get 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 1767.721518
The remainder is 78 after subtracting 632 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
79 goes into 780 9 times with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 1767.7215189
Deduct 711 from 780 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
If we divide 690 by 79, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 1767.72151898
If we take 632 away from 690, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 1767.72151898 with a balance of 5.8e-08.
