Let's divide 16921243 by 452
The aim is to understand the frequency of 452 in 16921243.

Let's proceed to step 1:
1 divided by 452 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 452

Moving on to step 2:
452 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 452

Moving on to step 3:
452 can be fit into 169 0 times, resulting in a remainder of 169.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 169 leaves us with 169.
Grab the next digit (2) from the dividend, add it to 169, then carry on: 1692 / 452

Advancing to step 4:
452 can be fit into 1692 3 times, resulting in a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1356 away from 1692, we end up with 336.
Grab the next digit (1) from the dividend, add it to 336, then carry on: 3361 / 452

On to step 5:
The number 452 fits into 3361 7 times, leaving a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtract 3164 from 3361 to get 197.
Take the next digit (2) from the dividend and append it to 197, then repeat: 1972 / 452

Moving on to step 6:
1972 divided by 452 is 4 with a remainder of 164.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Deduct 1808 from 1972 and we're left with 164.
Bring next digit (4) of the dividend behind the 164 and repeat the process: 1644 / 452

Advancing to step 7:
When dividing 1644 by 452, we get 3 with a remainder of 288.
The number 3 becomes the next digit in our result. 
Result so far: 3743.0
If we take 1356 away from 1644, we end up with 288.
Fetch the next digit (3) from the dividend, attach it to 288 and continue: 2883 / 452

Going ahead to step 8:
The number 452 fits into 2883 6 times, leaving a remainder of 171.
Put 6 as the next digit of the answer. 
Result so far: 37436.0
Subtract 2712 from 2883 to get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 9:
452 goes into 1710 3 times with a remainder of 354.
Write down 3 as next digit of the result. 
Result so far: 37436.3
Deduct 1356 from 1710 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
If we divide 3540 by 452, we get 7 and a remainder of 376.
Write down 7 as next digit of the result. 
Result so far: 37436.37
The remainder is 376 after subtracting 3164 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 11:
452 goes into 3760 8 times with a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 37436.378
Subtract 3616 from 3760 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
1440 divided by 452 is 3 with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 37436.3783
If we subtract 1356 from 1440, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 13:
452 goes into 840 1 times with a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 37436.37831
Deduct 452 from 840 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 14:
The number 452 fits into 3880 8 times, leaving a remainder of 264.
Write down 8 as next digit of the result. 
Result so far: 37436.378318
Subtract 3616 from 3880 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 15:
When dividing 2640 by 452, we get 5 with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 37436.3783185
If we subtract 2260 from 2640, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 16:
If we divide 3800 by 452, we get 8 and a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 37436.37831858
Deduct 3616 from 3800 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 37436.37831858, with a leftover of 1.84e-07.
