12944565 ÷ 550 
The aim is to understand the frequency of 550 in 12944565.

Let's proceed to step 1:
550 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 550

Step 2:
If we divide 12 by 550, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 550

Step 3:
129 divided by 550 is 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Take the next digit (4) from the dividend and append it to 129, then repeat: 1294 / 550

Step 4:
The number 550 fits into 1294 2 times, leaving a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1100 from 1294, we get 194.
Take the next digit (4) from the dividend and append it to 194, then repeat: 1944 / 550

Going ahead to step 5:
If we divide 1944 by 550, we get 3 and a remainder of 294.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 294 after subtracting 1650 from 1944.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 550

Moving on to step 6:
If we divide 2945 by 550, we get 5 and a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 235.0
Subtracting 2750 from 2945 leaves us with 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 550

Step 7:
If we divide 1956 by 550, we get 3 and a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 2353.0
The remainder is 306 after subtracting 1650 from 1956.
Append the next digit (5) from the dividend to 306 and continue with: 3065 / 550

On to step 8:
550 goes into 3065 5 times with a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 23535.0
Deduct 2750 from 3065 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 9:
The number 550 fits into 3150 5 times, leaving a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 23535.5
The remainder is 400 after subtracting 2750 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
550 goes into 4000 7 times with a remainder of 150.
The number 7 becomes the next digit in our result. 
Result so far: 23535.57
If we subtract 3850 from 4000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
550 can be fit into 1500 2 times, resulting in a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 23535.572
The remainder is 400 after subtracting 1100 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 12:
550 goes into 4000 7 times with a remainder of 150.
Put 7 as the next digit of the answer. 
Result so far: 23535.5727
Deduct 3850 from 4000 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
If we divide 1500 by 550, we get 2 and a remainder of 400.
Use 2 as the next digit of our solution. 
Result so far: 23535.57272
Deduct 1100 from 1500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
4000 divided by 550 is 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 23535.572727
Subtracting 3850 from 4000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
If we divide 1500 by 550, we get 2 and a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 23535.5727272
The remainder is 400 after subtracting 1100 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
550 can be fit into 4000 7 times, resulting in a remainder of 150.
The next digit of our result is 7. 
Result so far: 23535.57272727
Subtracting 3850 from 4000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

In conclusion, the division gives 23535.57272727 with a balance of 1.5e-07.
