20638929 divided by 79 
The aim is to understand the frequency of 79 in 20638929.

Moving on to step 1:
79 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 79

Let's proceed to step 2:
When dividing 20 by 79, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 79

Advancing to step 3:
If we divide 206 by 79, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 158 from 206 and we're left with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 79

Moving on to step 4:
The number 79 fits into 483 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 474 away from 483, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 79

Let's proceed to step 5:
The number 79 fits into 98 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
The remainder is 19 after subtracting 79 from 98.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 79

Moving on to step 6:
79 goes into 199 2 times with a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 2612.0
If we subtract 158 from 199, we get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 79

Moving on to step 7:
The number 79 fits into 412 5 times, leaving a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 26125.0
The remainder is 17 after subtracting 395 from 412.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 79

Let's proceed to step 8:
The number 79 fits into 179 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 261252.0
If we subtract 158 from 179, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
When dividing 210 by 79, we get 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 261252.2
If we subtract 158 from 210, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
79 can be fit into 520 6 times, resulting in a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 261252.26
The remainder is 46 after subtracting 474 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
460 divided by 79 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 261252.265
If we take 395 away from 460, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 12:
If we divide 650 by 79, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 261252.2658
The remainder is 18 after subtracting 632 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
The number 79 fits into 180 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 261252.26582
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 79, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 261252.265822
Subtracting 158 from 220 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 261252.265822, with a leftover of 6.2e-06.
