643432 ÷ 44 
The aim is to understand the frequency of 44 in 643432.

Going ahead to step 1:
The number 44 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 44

Advancing to step 2:
When dividing 64 by 44, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 44 from 64 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 44

Step 3:
When dividing 203 by 44, we get 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 176 from 203 leaves us with 27.
Grab the next digit (4) from the dividend, add it to 27, then carry on: 274 / 44

Advancing to step 4:
274 divided by 44 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 146.0
Subtract 264 from 274 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 44

On to step 5:
When dividing 103 by 44, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 1462.0
Deduct 88 from 103 and we're left with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 44

Step 6:
44 goes into 152 3 times with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 14623.0
The remainder is 20 after subtracting 132 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
44 goes into 200 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 14623.4
The remainder is 24 after subtracting 176 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
The number 44 fits into 240 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14623.45
If we subtract 220 from 240, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
44 can be fit into 200 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14623.454
Deduct 176 from 200 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
240 divided by 44 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14623.4545
Subtract 220 from 240 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 44 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 14623.45454
If we subtract 176 from 200, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
If we divide 240 by 44, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 14623.454545
The remainder is 20 after subtracting 220 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
44 can be fit into 200 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 14623.4545454
Subtracting 176 from 200 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
The number 44 fits into 240 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 14623.45454545
The remainder is 20 after subtracting 220 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 14623.45454545 with a remainder of 2e-08.
