72336596 ÷ 550 
The aim is to understand the frequency of 550 in 72336596.

Step 1:
7 divided by 550 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 550

Step 2:
When dividing 72 by 550, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 550

Advancing to step 3:
The number 550 fits into 723 1 times, leaving a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 173 after subtracting 550 from 723.
Grab the next digit (3) from the dividend, add it to 173, then carry on: 1733 / 550

Moving on to step 4:
550 can be fit into 1733 3 times, resulting in a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1650 from 1733, we get 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 550

Going ahead to step 5:
836 divided by 550 is 1 with a remainder of 286.
The next digit of our result is 1. 
Result so far: 131.0
Deduct 550 from 836 and we're left with 286.
Append the next digit (5) from the dividend to 286 and continue with: 2865 / 550

Moving on to step 6:
The number 550 fits into 2865 5 times, leaving a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 1315.0
The remainder is 115 after subtracting 2750 from 2865.
Append the next digit (9) from the dividend to 115 and continue with: 1159 / 550

Moving on to step 7:
550 goes into 1159 2 times with a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 13152.0
If we take 1100 away from 1159, we end up with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 550

Moving on to step 8:
550 goes into 596 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 131521.0
Subtract 550 from 596 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
If we divide 460 by 550, we get 0 and a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 131521.0
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 10:
When dividing 4600 by 550, we get 8 with a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 131521.08
If we subtract 4400 from 4600, 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.

On to step 11:
The number 550 fits into 2000 3 times, leaving a remainder of 350.
Write down 3 as next digit of the result. 
Result so far: 131521.083
Deduct 1650 from 2000 and we're left 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.

Advancing to step 12:
When dividing 3500 by 550, we get 6 with a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 131521.0836
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.

Let's proceed to step 13:
The number 550 fits into 2000 3 times, leaving a remainder of 350.
Put 3 as the next digit of the answer. 
Result so far: 131521.08363
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:
3500 divided by 550 is 6 with a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 131521.083636
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.

Going ahead to step 15:
When dividing 2000 by 550, we get 3 with a remainder of 350.
Write down 3 as next digit of the result. 
Result so far: 131521.0836363
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: 131521.08363636
Subtracting 3300 from 3500 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.

After the division, we end up with 131521.08363636 and a remainder of 2e-07.
