We divide 648686 by 79
The aim is to understand the frequency of 79 in 648686.

On to step 1:
If we divide 6 by 79, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 79

Advancing to step 2:
When dividing 64 by 79, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 79

Let's proceed to step 3:
If we divide 648 by 79, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 16 after subtracting 632 from 648.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 79

Moving on to step 4:
79 can be fit into 166 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 8 after subtracting 158 from 166.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 79

Advancing to step 5:
If we divide 88 by 79, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 821.0
Subtracting 79 from 88 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 79

Advancing to step 6:
The number 79 fits into 96 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 8211.0
If we take 79 away from 96, we end up 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.

On to step 7:
When dividing 170 by 79, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 8211.2
If we subtract 158 from 170, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 79 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 8211.21
Deduct 79 from 120 and we're left with 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 9:
The number 79 fits into 410 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8211.215
If we subtract 395 from 410, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 79, we get 1 and a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 8211.2151
Subtract 79 from 150 to 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.

On to step 11:
79 goes into 710 8 times with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 8211.21518
Subtract 632 from 710 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
The number 79 fits into 780 9 times, leaving a remainder of 69.
The next digit of our result is 9. 
Result so far: 8211.215189
Subtracting 711 from 780 leaves us 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.

Moving on to step 13:
79 goes into 690 8 times with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 8211.2151898
Subtracting 632 from 690 leaves us 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.

Going ahead to step 14:
79 can be fit into 580 7 times, resulting in a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 8211.21518987
If we subtract 553 from 580, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 8211.21518987, and the remainder is 2.7e-08.
