Let's divide 80368539 by 550
The aim is to understand the frequency of 550 in 80368539.

Going ahead to step 1:
When dividing 8 by 550, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 550

Advancing to step 2:
If we divide 80 by 550, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 550

Let's proceed to step 3:
550 can be fit into 803 1 times, resulting in a remainder of 253.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 550 from 803 to get 253.
Bring next digit (6) of the dividend behind the 253 and repeat the process: 2536 / 550

Step 4:
When dividing 2536 by 550, we get 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2200 from 2536, we get 336.
Grab the next digit (8) from the dividend, add it to 336, then carry on: 3368 / 550

Advancing to step 5:
3368 divided by 550 is 6 with a remainder of 68.
The next digit of our result is 6. 
Result so far: 146.0
The remainder is 68 after subtracting 3300 from 3368.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 550

Advancing to step 6:
If we divide 685 by 550, we get 1 and a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
Subtracting 550 from 685 leaves us with 135.
Fetch the next digit (3) from the dividend, attach it to 135 and continue: 1353 / 550

Let's proceed to step 7:
The number 550 fits into 1353 2 times, leaving a remainder of 253.
The number 2 becomes the next digit in our result. 
Result so far: 14612.0
Subtracting 1100 from 1353 leaves us with 253.
Include the next digit (9) from the dividend after 253, then repeat: 2539 / 550

On to step 8:
550 can be fit into 2539 4 times, resulting in a remainder of 339.
Write down 4 as next digit of the result. 
Result so far: 146124.0
Deduct 2200 from 2539 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 9:
When dividing 3390 by 550, we get 6 with a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 146124.6
The remainder is 90 after subtracting 3300 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
The number 550 fits into 900 1 times, leaving a remainder of 350.
The next digit of our result is 1. 
Result so far: 146124.61
Subtracting 550 from 900 leaves us 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.

Going ahead to step 11:
550 can be fit into 3500 6 times, resulting in a remainder of 200.
The next digit of our result is 6. 
Result so far: 146124.616
The remainder is 200 after subtracting 3300 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
The number 550 fits into 2000 3 times, leaving a remainder of 350.
The number 3 becomes the next digit in our result. 
Result so far: 146124.6163
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.

Moving on to step 13:
The number 550 fits into 3500 6 times, leaving a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 146124.61636
Deduct 3300 from 3500 and we're left 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.

Advancing to step 14:
When dividing 2000 by 550, we get 3 with a remainder of 350.
The number 3 becomes the next digit in our result. 
Result so far: 146124.616363
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.

Advancing to step 15:
If we divide 3500 by 550, we get 6 and a remainder of 200.
Put 6 as the next digit of the answer. 
Result so far: 146124.6163636
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.

Let's proceed to step 16:
When dividing 2000 by 550, we get 3 with a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 146124.61636363
Subtract 1650 from 2000 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 146124.61636363 and a remainder of 3.5e-07.
