121828 ÷ 79 
The aim is to understand the frequency of 79 in 121828.

On to step 1:
1 divided by 79 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 79

Step 2:
When dividing 12 by 79, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 79

Going ahead to step 3:
79 can be fit into 121 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 79 from 121 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 79

Moving on to step 4:
79 can be fit into 428 5 times, resulting in a remainder of 33.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 395 from 428 to get 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 79

Going ahead to step 5:
The number 79 fits into 332 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 316 away from 332, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 79

Let's proceed to step 6:
When dividing 168 by 79, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1542.0
Subtracting 158 from 168 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 79 fits into 100 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1542.1
Subtract 79 from 100 to 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.

Let's proceed to step 8:
If we divide 210 by 79, we get 2 and a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 1542.12
Subtracting 158 from 210 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 79 fits into 520 6 times, leaving a remainder of 46.
The next digit of our result is 6. 
Result so far: 1542.126
Deduct 474 from 520 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
460 divided by 79 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 1542.1265
Subtract 395 from 460 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
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: 1542.12658
Subtract 632 from 650 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
79 goes into 180 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1542.126582
The remainder is 22 after subtracting 158 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
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: 1542.1265822
If we take 158 away from 220, we end up 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 1542.1265822, with a leftover of 6.2e-07.
