We're dividing 20570288 by 550 
The aim is to understand the frequency of 550 in 20570288.

Step 1:
When dividing 2 by 550, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 550

Advancing to step 2:
20 divided by 550 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 550

Advancing to step 3:
If we divide 205 by 550, we get 0 and a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Bring next digit (7) of the dividend behind the 205 and repeat the process: 2057 / 550

Moving on to step 4:
The number 550 fits into 2057 3 times, leaving a remainder of 407.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1650 from 2057 to get 407.
Bring next digit (0) of the dividend behind the 407 and repeat the process: 4070 / 550

Let's proceed to step 5:
If we divide 4070 by 550, we get 7 and a remainder of 220.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 3850 away from 4070, we end up with 220.
Include the next digit (2) from the dividend after 220, then repeat: 2202 / 550

Advancing to step 6:
When dividing 2202 by 550, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 374.0
The remainder is 2 after subtracting 2200 from 2202.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 550

Step 7:
28 divided by 550 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 3740.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 550

Let's proceed to step 8:
550 goes into 288 0 times with a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 37400.0
Deduct 0 from 288 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 9:
550 goes into 2880 5 times with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 37400.5
Subtract 2750 from 2880 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 550, we get 2 with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 37400.52
Subtracting 1100 from 1300 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
If we divide 2000 by 550, we get 3 and a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 37400.523
The remainder is 350 after subtracting 1650 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
550 can be fit into 3500 6 times, resulting in a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 37400.5236
If we subtract 3300 from 3500, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
If we divide 2000 by 550, we get 3 and a remainder of 350.
Put 3 as the next digit of the answer. 
Result so far: 37400.52363
If we take 1650 away from 2000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 14:
550 goes into 3500 6 times with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 37400.523636
If we take 3300 away from 3500, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
550 goes into 2000 3 times with a remainder of 350.
Write down 3 as next digit of the result. 
Result so far: 37400.5236363
If we take 1650 away from 2000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 16:
550 goes into 3500 6 times with a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 37400.52363636
Subtract 3300 from 3500 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 37400.52363636 with a remainder of 2e-07.
