Let's divide 12776735 by 803
The aim is to understand the frequency of 803 in 12776735.

Advancing to step 1:
1 divided by 803 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 803

Moving on to step 2:
If we divide 12 by 803, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 803

Step 3:
The number 803 fits into 127 0 times, leaving a remainder of 127.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 127 and we're left with 127.
Fetch the next digit (7) from the dividend, attach it to 127 and continue: 1277 / 803

Going ahead to step 4:
The number 803 fits into 1277 1 times, leaving a remainder of 474.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 474 after subtracting 803 from 1277.
Take the next digit (6) from the dividend and append it to 474, then repeat: 4746 / 803

Advancing to step 5:
The number 803 fits into 4746 5 times, leaving a remainder of 731.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 4015 from 4746 leaves us with 731.
Include the next digit (7) from the dividend after 731, then repeat: 7317 / 803

Going ahead to step 6:
7317 divided by 803 is 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we take 7227 away from 7317, we end up with 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 803

Step 7:
803 can be fit into 903 1 times, resulting in a remainder of 100.
The next digit of our result is 1. 
Result so far: 1591.0
Subtract 803 from 903 to get 100.
Grab the next digit (5) from the dividend, add it to 100, then carry on: 1005 / 803

Going ahead to step 8:
1005 divided by 803 is 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 15911.0
The remainder is 202 after subtracting 803 from 1005.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 9:
When dividing 2020 by 803, we get 2 with a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 15911.2
The remainder is 414 after subtracting 1606 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 10:
When dividing 4140 by 803, we get 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 15911.25
The remainder is 125 after subtracting 4015 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
When dividing 1250 by 803, we get 1 with a remainder of 447.
Record the quotient 1 as the next digit in the result. 
Result so far: 15911.251
The remainder is 447 after subtracting 803 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 12:
803 goes into 4470 5 times with a remainder of 455.
The next digit of our result is 5. 
Result so far: 15911.2515
If we subtract 4015 from 4470, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 13:
4550 divided by 803 is 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 15911.25155
Deduct 4015 from 4550 and we're left with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Our division results in 15911.25155 with a remaining 0.000535.
