43638897 ÷ 924 
The aim is to understand the frequency of 924 in 43638897.

On to step 1:
When dividing 4 by 924, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 924

Going ahead to step 2:
924 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 924

Advancing to step 3:
The number 924 fits into 436 0 times, leaving a remainder of 436.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 436 after subtracting 0 from 436.
Take the next digit (3) from the dividend and append it to 436, then repeat: 4363 / 924

Let's proceed to step 4:
924 goes into 4363 4 times with a remainder of 667.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3696 away from 4363, we end up with 667.
Bring next digit (8) of the dividend behind the 667 and repeat the process: 6678 / 924

Advancing to step 5:
If we divide 6678 by 924, we get 7 and a remainder of 210.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 6468 from 6678 leaves us with 210.
Fetch the next digit (8) from the dividend, attach it to 210 and continue: 2108 / 924

Going ahead to step 6:
When dividing 2108 by 924, we get 2 with a remainder of 260.
Record the quotient 2 as the next digit in the result. 
Result so far: 472.0
Subtracting 1848 from 2108 leaves us with 260.
Take the next digit (9) from the dividend and append it to 260, then repeat: 2609 / 924

Moving on to step 7:
924 can be fit into 2609 2 times, resulting in a remainder of 761.
Put 2 as the next digit of the answer. 
Result so far: 4722.0
Subtract 1848 from 2609 to get 761.
Bring next digit (7) of the dividend behind the 761 and repeat the process: 7617 / 924

Step 8:
The number 924 fits into 7617 8 times, leaving a remainder of 225.
Record the quotient 8 as the next digit in the result. 
Result so far: 47228.0
If we subtract 7392 from 7617, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 9:
924 goes into 2250 2 times with a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 47228.2
If we subtract 1848 from 2250, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 10:
924 can be fit into 4020 4 times, resulting in a remainder of 324.
Write down 4 as next digit of the result. 
Result so far: 47228.24
If we take 3696 away from 4020, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 11:
924 can be fit into 3240 3 times, resulting in a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 47228.243
Subtracting 2772 from 3240 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 12:
If we divide 4680 by 924, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 47228.2435
The remainder is 60 after subtracting 4620 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
924 goes into 600 0 times with a remainder of 600.
The next digit of our result is 0. 
Result so far: 47228.2435
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 14:
924 goes into 6000 6 times with a remainder of 456.
The next digit of our result is 6. 
Result so far: 47228.243506
Subtracting 5544 from 6000 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 15:
The number 924 fits into 4560 4 times, leaving a remainder of 864.
Put 4 as the next digit of the answer. 
Result so far: 47228.2435064
If we take 3696 away from 4560, we end up with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

Going ahead to step 16:
When dividing 8640 by 924, we get 9 with a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 47228.24350649
If we subtract 8316 from 8640, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 47228.24350649 with a remainder of 3.24e-07.
