We're dividing 21317472 by 774 
The aim is to understand the frequency of 774 in 21317472.

Let's proceed to step 1:
774 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 774

On to step 2:
774 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 774

Let's proceed to step 3:
213 divided by 774 is 0 with a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 774

On to step 4:
2131 divided by 774 is 2 with a remainder of 583.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1548 from 2131, we get 583.
Append the next digit (7) from the dividend to 583 and continue with: 5837 / 774

Step 5:
The number 774 fits into 5837 7 times, leaving a remainder of 419.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 5418 away from 5837, we end up with 419.
Include the next digit (4) from the dividend after 419, then repeat: 4194 / 774

Moving on to step 6:
If we divide 4194 by 774, we get 5 and a remainder of 324.
Use 5 as the next digit of our solution. 
Result so far: 275.0
Deduct 3870 from 4194 and we're left with 324.
Bring next digit (7) of the dividend behind the 324 and repeat the process: 3247 / 774

Moving on to step 7:
774 goes into 3247 4 times with a remainder of 151.
Put 4 as the next digit of the answer. 
Result so far: 2754.0
If we take 3096 away from 3247, we end up with 151.
Bring next digit (2) of the dividend behind the 151 and repeat the process: 1512 / 774

Going ahead to step 8:
774 can be fit into 1512 1 times, resulting in a remainder of 738.
Put 1 as the next digit of the answer. 
Result so far: 27541.0
If we take 774 away from 1512, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Advancing to step 9:
774 can be fit into 7380 9 times, resulting in a remainder of 414.
Write down 9 as next digit of the result. 
Result so far: 27541.9
Deduct 6966 from 7380 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
The number 774 fits into 4140 5 times, leaving a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 27541.95
Subtracting 3870 from 4140 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
When dividing 2700 by 774, we get 3 with a remainder of 378.
Record the quotient 3 as the next digit in the result. 
Result so far: 27541.953
If we take 2322 away from 2700, we end up with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 12:
If we divide 3780 by 774, we get 4 and a remainder of 684.
The next digit of our result is 4. 
Result so far: 27541.9534
If we take 3096 away from 3780, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 13:
If we divide 6840 by 774, we get 8 and a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 27541.95348
If we take 6192 away from 6840, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 14:
6480 divided by 774 is 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 27541.953488
Deduct 6192 from 6480 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 27541.953488 and a remainder of 2.88e-05.
