We look at the division of 80399409 by 773 
The aim is to understand the frequency of 773 in 80399409.

On to step 1:
8 divided by 773 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 773

Moving on to step 2:
The number 773 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (3) of the dividend behind the 80 and repeat the process: 803 / 773

Step 3:
If we divide 803 by 773, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 773 from 803, we get 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 773

Moving on to step 4:
When dividing 309 by 773, we get 0 with a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 309 and we're left with 309.
Bring next digit (9) of the dividend behind the 309 and repeat the process: 3099 / 773

Step 5:
The number 773 fits into 3099 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 7 after subtracting 3092 from 3099.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 773

Going ahead to step 6:
If we divide 74 by 773, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 1040.0
Subtracting 0 from 74 leaves us with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 773

Moving on to step 7:
773 can be fit into 740 0 times, resulting in a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 10400.0
Deduct 0 from 740 and we're left with 740.
Grab the next digit (9) from the dividend, add it to 740, then carry on: 7409 / 773

Moving on to step 8:
773 can be fit into 7409 9 times, resulting in a remainder of 452.
Record the quotient 9 as the next digit in the result. 
Result so far: 104009.0
Subtract 6957 from 7409 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 9:
The number 773 fits into 4520 5 times, leaving a remainder of 655.
Put 5 as the next digit of the answer. 
Result so far: 104009.5
The remainder is 655 after subtracting 3865 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 10:
6550 divided by 773 is 8 with a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 104009.58
Subtract 6184 from 6550 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 11:
3660 divided by 773 is 4 with a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 104009.584
If we subtract 3092 from 3660, we get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
773 can be fit into 5680 7 times, resulting in a remainder of 269.
Use 7 as the next digit of our solution. 
Result so far: 104009.5847
The remainder is 269 after subtracting 5411 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 13:
773 goes into 2690 3 times with a remainder of 371.
Record the quotient 3 as the next digit in the result. 
Result so far: 104009.58473
If we subtract 2319 from 2690, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 14:
773 can be fit into 3710 4 times, resulting in a remainder of 618.
Use 4 as the next digit of our solution. 
Result so far: 104009.584734
Subtract 3092 from 3710 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 15:
773 can be fit into 6180 7 times, resulting in a remainder of 769.
Write down 7 as next digit of the result. 
Result so far: 104009.5847347
If we take 5411 away from 6180, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Moving on to step 16:
7690 divided by 773 is 9 with a remainder of 733.
The next digit of our result is 9. 
Result so far: 104009.58473479
Subtracting 6957 from 7690 leaves us with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

In conclusion, the division gives 104009.58473479 with a balance of 7.33e-07.
