We're dividing 16921323 by 753 
The aim is to understand the frequency of 753 in 16921323.

On to step 1:
753 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 753

Step 2:
When dividing 16 by 753, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 753

Step 3:
753 can be fit into 169 0 times, resulting in a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 169 to get 169.
Include the next digit (2) from the dividend after 169, then repeat: 1692 / 753

Step 4:
If we divide 1692 by 753, we get 2 and a remainder of 186.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1506 from 1692 to get 186.
Include the next digit (1) from the dividend after 186, then repeat: 1861 / 753

Going ahead to step 5:
If we divide 1861 by 753, we get 2 and a remainder of 355.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 1506 from 1861 to get 355.
Fetch the next digit (3) from the dividend, attach it to 355 and continue: 3553 / 753

Moving on to step 6:
The number 753 fits into 3553 4 times, leaving a remainder of 541.
Use 4 as the next digit of our solution. 
Result so far: 224.0
If we subtract 3012 from 3553, we get 541.
Include the next digit (2) from the dividend after 541, then repeat: 5412 / 753

Let's proceed to step 7:
When dividing 5412 by 753, we get 7 with a remainder of 141.
Put 7 as the next digit of the answer. 
Result so far: 2247.0
If we take 5271 away from 5412, we end up with 141.
Fetch the next digit (3) from the dividend, attach it to 141 and continue: 1413 / 753

Step 8:
The number 753 fits into 1413 1 times, leaving a remainder of 660.
The number 1 becomes the next digit in our result. 
Result so far: 22471.0
If we subtract 753 from 1413, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 9:
753 can be fit into 6600 8 times, resulting in a remainder of 576.
Write down 8 as next digit of the result. 
Result so far: 22471.8
Subtracting 6024 from 6600 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

On to step 10:
753 can be fit into 5760 7 times, resulting in a remainder of 489.
Use 7 as the next digit of our solution. 
Result so far: 22471.87
If we subtract 5271 from 5760, we get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 11:
The number 753 fits into 4890 6 times, leaving a remainder of 372.
The next digit of our result is 6. 
Result so far: 22471.876
If we subtract 4518 from 4890, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 12:
3720 divided by 753 is 4 with a remainder of 708.
Write down 4 as next digit of the result. 
Result so far: 22471.8764
If we take 3012 away from 3720, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 13:
The number 753 fits into 7080 9 times, leaving a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 22471.87649
If we subtract 6777 from 7080, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 14:
753 can be fit into 3030 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 22471.876494
Subtracting 3012 from 3030 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
753 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 22471.876494
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 16:
1800 divided by 753 is 2 with a remainder of 294.
Write down 2 as next digit of the result. 
Result so far: 22471.87649402
Deduct 1506 from 1800 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

In conclusion, the division gives 22471.87649402 with a balance of 2.94e-07.
