We look at the division of 11389581 by 550 
The aim is to understand the frequency of 550 in 11389581.

Step 1:
If we divide 1 by 550, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 550

Let's proceed to step 2:
The number 550 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 550

On to step 3:
The number 550 fits into 113 0 times, leaving a remainder of 113.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 113 after subtracting 0 from 113.
Fetch the next digit (8) from the dividend, attach it to 113 and continue: 1138 / 550

Moving on to step 4:
If we divide 1138 by 550, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 38 after subtracting 1100 from 1138.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 550

Moving on to step 5:
If we divide 389 by 550, we get 0 and a remainder of 389.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 389, we end up with 389.
Bring next digit (5) of the dividend behind the 389 and repeat the process: 3895 / 550

Step 6:
The number 550 fits into 3895 7 times, leaving a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Subtracting 3850 from 3895 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 550

Moving on to step 7:
When dividing 458 by 550, we get 0 with a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 2070.0
Subtracting 0 from 458 leaves us with 458.
Append the next digit (1) from the dividend to 458 and continue with: 4581 / 550

Going ahead to step 8:
If we divide 4581 by 550, we get 8 and a remainder of 181.
Put 8 as the next digit of the answer. 
Result so far: 20708.0
Subtract 4400 from 4581 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 9:
550 can be fit into 1810 3 times, resulting in a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 20708.3
The remainder is 160 after subtracting 1650 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
1600 divided by 550 is 2 with a remainder of 500.
Put 2 as the next digit of the answer. 
Result so far: 20708.32
If we take 1100 away from 1600, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
550 goes into 5000 9 times with a remainder of 50.
The next digit of our result is 9. 
Result so far: 20708.329
Subtracting 4950 from 5000 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
550 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 20708.329
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 13:
If we divide 5000 by 550, we get 9 and a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 20708.32909
The remainder is 50 after subtracting 4950 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 550 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 20708.32909
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 15:
When dividing 5000 by 550, we get 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 20708.3290909
If we subtract 4950 from 5000, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 16:
If we divide 500 by 550, we get 0 and a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 20708.3290909
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 20708.3290909 and a remainder of 5e-07.
