421336 divided by 79 
The aim is to understand the frequency of 79 in 421336.

On to step 1:
If we divide 4 by 79, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 79

Moving on to step 2:
79 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 79

Moving on to step 3:
The number 79 fits into 421 5 times, leaving a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 395 from 421, we get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 79

Step 4:
263 divided by 79 is 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 237 from 263 leaves us with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 79

Going ahead to step 5:
The number 79 fits into 263 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 533.0
Subtract 237 from 263 to get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 79

On to step 6:
266 divided by 79 is 3 with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 5333.0
The remainder is 29 after subtracting 237 from 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
If we divide 290 by 79, we get 3 and a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 5333.3
Subtracting 237 from 290 leaves us 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.

Let's proceed to step 8:
530 divided by 79 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 5333.36
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 9:
If we divide 560 by 79, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 5333.367
Subtracting 553 from 560 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
When dividing 70 by 79, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 5333.367
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.

Step 11:
If we divide 700 by 79, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 5333.36708
If we take 632 away from 700, we end up 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.

On to step 12:
79 goes into 680 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 5333.367088
Subtracting 632 from 680 leaves us with 48.
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 5333.367088 and a remainder of 4.8e-06.
