We look at the division of 285421 by 44 
The aim is to understand the frequency of 44 in 285421.

Let's proceed to step 1:
44 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 44

Advancing to step 2:
44 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 44

On to step 3:
The number 44 fits into 285 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 6.0
If we take 264 away from 285, we end up with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 44

On to step 4:
214 divided by 44 is 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 176 from 214, we get 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 44

Advancing to step 5:
44 can be fit into 382 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 648.0
If we take 352 away from 382, we end up with 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 44

Let's proceed to step 6:
301 divided by 44 is 6 with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 6486.0
If we subtract 264 from 301, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
44 goes into 370 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 6486.8
If we subtract 352 from 370, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
The number 44 fits into 180 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 6486.84
Subtracting 176 from 180 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.

Let's proceed to step 9:
If we divide 40 by 44, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6486.84
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.

Going ahead to step 10:
When dividing 400 by 44, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 6486.8409
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.

Advancing to step 11:
44 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 6486.8409
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.

Moving on to step 12:
The number 44 fits into 400 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 6486.840909
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.

Moving on to step 13:
The number 44 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6486.840909
Subtracting 0 from 40 leaves us 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.

Step 14:
When dividing 400 by 44, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 6486.84090909
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.

After the division, we end up with 6486.84090909 and a remainder of 4e-09.
