17993607 ÷ 444 
The aim is to understand the frequency of 444 in 17993607.

Moving on to step 1:
When dividing 1 by 444, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 444

On to step 2:
17 divided by 444 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 444

Let's proceed to step 3:
If we divide 179 by 444, we get 0 and a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 179 leaves us with 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 444

Advancing to step 4:
444 goes into 1799 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1776 from 1799 to get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 444

Let's proceed to step 5:
444 can be fit into 233 0 times, resulting in a remainder of 233.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 233, we end up with 233.
Bring next digit (6) of the dividend behind the 233 and repeat the process: 2336 / 444

Moving on to step 6:
2336 divided by 444 is 5 with a remainder of 116.
Use 5 as the next digit of our solution. 
Result so far: 405.0
Subtract 2220 from 2336 to get 116.
Include the next digit (0) from the dividend after 116, then repeat: 1160 / 444

Let's proceed to step 7:
444 can be fit into 1160 2 times, resulting in a remainder of 272.
Write down 2 as next digit of the result. 
Result so far: 4052.0
The remainder is 272 after subtracting 888 from 1160.
Bring next digit (7) of the dividend behind the 272 and repeat the process: 2727 / 444

Going ahead to step 8:
2727 divided by 444 is 6 with a remainder of 63.
The next digit of our result is 6. 
Result so far: 40526.0
Subtract 2664 from 2727 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
444 can be fit into 630 1 times, resulting in a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 40526.1
Subtract 444 from 630 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
If we divide 1860 by 444, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 40526.14
Deduct 1776 from 1860 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:
444 can be fit into 840 1 times, resulting in a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 40526.141
If we take 444 away from 840, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 12:
444 can be fit into 3960 8 times, resulting in a remainder of 408.
Record the quotient 8 as the next digit in the result. 
Result so far: 40526.1418
Subtract 3552 from 3960 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 13:
4080 divided by 444 is 9 with a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 40526.14189
Subtract 3996 from 4080 to 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.

Moving on to step 14:
444 goes into 840 1 times with a remainder of 396.
Record the quotient 1 as the next digit in the result. 
Result so far: 40526.141891
Subtracting 444 from 840 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
3960 divided by 444 is 8 with a remainder of 408.
The next digit of our result is 8. 
Result so far: 40526.1418918
Deduct 3552 from 3960 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 16:
The number 444 fits into 4080 9 times, leaving a remainder of 84.
The next digit of our result is 9. 
Result so far: 40526.14189189
Subtracting 3996 from 4080 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 40526.14189189, with a leftover of 8.4e-08.
