We divide 77315996 by 550
The aim is to understand the frequency of 550 in 77315996.

On to step 1:
If we divide 7 by 550, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 550

On to step 2:
77 divided by 550 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 550

Advancing to step 3:
550 can be fit into 773 1 times, resulting in a remainder of 223.
The next digit of our result is 1. 
Result so far: 1.0
If we take 550 away from 773, we end up with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 550

Advancing to step 4:
If we divide 2231 by 550, we get 4 and a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 31 after subtracting 2200 from 2231.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 550

Going ahead to step 5:
When dividing 315 by 550, we get 0 with a remainder of 315.
The next digit of our result is 0. 
Result so far: 140.0
Deduct 0 from 315 and we're left with 315.
Take the next digit (9) from the dividend and append it to 315, then repeat: 3159 / 550

Let's proceed to step 6:
When dividing 3159 by 550, we get 5 with a remainder of 409.
Write down 5 as next digit of the result. 
Result so far: 1405.0
The remainder is 409 after subtracting 2750 from 3159.
Take the next digit (9) from the dividend and append it to 409, then repeat: 4099 / 550

On to step 7:
4099 divided by 550 is 7 with a remainder of 249.
The number 7 becomes the next digit in our result. 
Result so far: 14057.0
Subtracting 3850 from 4099 leaves us with 249.
Grab the next digit (6) from the dividend, add it to 249, then carry on: 2496 / 550

Step 8:
If we divide 2496 by 550, we get 4 and a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 140574.0
If we take 2200 away from 2496, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
550 goes into 2960 5 times with a remainder of 210.
Use 5 as the next digit of our solution. 
Result so far: 140574.5
Deduct 2750 from 2960 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
550 goes into 2100 3 times with a remainder of 450.
Write down 3 as next digit of the result. 
Result so far: 140574.53
If we subtract 1650 from 2100, we 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.

Moving on to step 11:
4500 divided by 550 is 8 with a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 140574.538
If we subtract 4400 from 4500, 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.

On to step 12:
The number 550 fits into 1000 1 times, leaving a remainder of 450.
The number 1 becomes the next digit in our result. 
Result so far: 140574.5381
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.

Going ahead to step 13:
The number 550 fits into 4500 8 times, leaving a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 140574.53818
Deduct 4400 from 4500 and we're left 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.

Moving on to step 14:
The number 550 fits into 1000 1 times, leaving a remainder of 450.
Record the quotient 1 as the next digit in the result. 
Result so far: 140574.538181
The remainder is 450 after subtracting 550 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 15:
The number 550 fits into 4500 8 times, leaving a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 140574.5381818
Deduct 4400 from 4500 and we're left 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.

On to step 16:
1000 divided by 550 is 1 with a remainder of 450.
Write down 1 as next digit of the result. 
Result so far: 140574.53818181
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.

The quotient of the division is 140574.53818181, and the remainder is 4.5e-07.
