821520 ÷ 44 
The aim is to understand the frequency of 44 in 821520.

On to step 1:
If we divide 8 by 44, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 44

Going ahead to step 2:
44 goes into 82 1 times with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 44 away from 82, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 44

Let's proceed to step 3:
44 goes into 381 8 times with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 352 away from 381, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 44

Moving on to step 4:
If we divide 295 by 44, we get 6 and a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
The remainder is 31 after subtracting 264 from 295.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 44

Advancing to step 5:
44 goes into 312 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 1867.0
If we subtract 308 from 312, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 44

Advancing to step 6:
44 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 18670.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
44 can be fit into 400 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 18670.9
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
44 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 18670.9
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 44 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 18670.909
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
44 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 18670.909
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
44 can be fit into 400 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 18670.90909
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
44 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 18670.90909
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
The number 44 fits into 400 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 18670.9090909
If we subtract 396 from 400, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
The number 44 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 18670.9090909
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 18670.9090909 with a remaining 4e-08.
