We're dividing 50644427 by 738 
The aim is to understand the frequency of 738 in 50644427.

On to step 1:
If we divide 5 by 738, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 738

Going ahead to step 2:
If we divide 50 by 738, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 738

Moving on to step 3:
If we divide 506 by 738, we get 0 and a remainder of 506.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 506 to get 506.
Take the next digit (4) from the dividend and append it to 506, then repeat: 5064 / 738

Advancing to step 4:
The number 738 fits into 5064 6 times, leaving a remainder of 636.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 636 after subtracting 4428 from 5064.
Include the next digit (4) from the dividend after 636, then repeat: 6364 / 738

On to step 5:
When dividing 6364 by 738, we get 8 with a remainder of 460.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 5904 from 6364 and we're left with 460.
Include the next digit (4) from the dividend after 460, then repeat: 4604 / 738

Going ahead to step 6:
When dividing 4604 by 738, we get 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 686.0
Deduct 4428 from 4604 and we're left with 176.
Bring next digit (2) of the dividend behind the 176 and repeat the process: 1762 / 738

Moving on to step 7:
738 can be fit into 1762 2 times, resulting in a remainder of 286.
The next digit of our result is 2. 
Result so far: 6862.0
If we subtract 1476 from 1762, we get 286.
Append the next digit (7) from the dividend to 286 and continue with: 2867 / 738

Let's proceed to step 8:
The number 738 fits into 2867 3 times, leaving a remainder of 653.
The next digit of our result is 3. 
Result so far: 68623.0
Subtracting 2214 from 2867 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 9:
738 can be fit into 6530 8 times, resulting in a remainder of 626.
The number 8 becomes the next digit in our result. 
Result so far: 68623.8
Subtract 5904 from 6530 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Let's proceed to step 10:
The number 738 fits into 6260 8 times, leaving a remainder of 356.
Put 8 as the next digit of the answer. 
Result so far: 68623.88
Deduct 5904 from 6260 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

In conclusion, the division gives 68623.88 with a balance of 0.356.
