Let's divide 78663234 by 550
The aim is to understand the frequency of 550 in 78663234.

On to step 1:
7 divided by 550 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 550

On to step 2:
550 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 550

Step 3:
786 divided by 550 is 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 550 from 786 leaves us with 236.
Include the next digit (6) from the dividend after 236, then repeat: 2366 / 550

Step 4:
The number 550 fits into 2366 4 times, leaving a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2200 from 2366, we get 166.
Include the next digit (3) from the dividend after 166, then repeat: 1663 / 550

Let's proceed to step 5:
The number 550 fits into 1663 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 143.0
The remainder is 13 after subtracting 1650 from 1663.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 550

Moving on to step 6:
550 can be fit into 132 0 times, resulting in a remainder of 132.
The next digit of our result is 0. 
Result so far: 1430.0
Subtract 0 from 132 to get 132.
Grab the next digit (3) from the dividend, add it to 132, then carry on: 1323 / 550

Step 7:
550 goes into 1323 2 times with a remainder of 223.
Record the quotient 2 as the next digit in the result. 
Result so far: 14302.0
The remainder is 223 after subtracting 1100 from 1323.
Take the next digit (4) from the dividend and append it to 223, then repeat: 2234 / 550

Advancing to step 8:
If we divide 2234 by 550, we get 4 and a remainder of 34.
The next digit of our result is 4. 
Result so far: 143024.0
Deduct 2200 from 2234 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
340 divided by 550 is 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 143024.0
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
3400 divided by 550 is 6 with a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 143024.06
If we subtract 3300 from 3400, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
1000 divided by 550 is 1 with a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 143024.061
Deduct 550 from 1000 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 12:
When dividing 4500 by 550, we get 8 with a remainder of 100.
The next digit of our result is 8. 
Result so far: 143024.0618
Subtract 4400 from 4500 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 13:
1000 divided by 550 is 1 with a remainder of 450.
Put 1 as the next digit of the answer. 
Result so far: 143024.06181
Subtracting 550 from 1000 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 14:
4500 divided by 550 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 143024.061818
The remainder is 100 after subtracting 4400 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 15:
If we divide 1000 by 550, we get 1 and a remainder of 450.
The number 1 becomes the next digit in our result. 
Result so far: 143024.0618181
Subtract 550 from 1000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 16:
When dividing 4500 by 550, we get 8 with a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 143024.06181818
If we take 4400 away from 4500, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 143024.06181818, with a leftover of 1e-07.
