We look at the division of 12714528 by 801 
The aim is to understand the frequency of 801 in 12714528.

Advancing to step 1:
The number 801 fits into 1 0 times, leaving 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.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 801

Moving on to step 2:
12 divided by 801 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 801

Advancing to step 3:
When dividing 127 by 801, we get 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 127 after subtracting 0 from 127.
Bring next digit (1) of the dividend behind the 127 and repeat the process: 1271 / 801

Going ahead to step 4:
801 goes into 1271 1 times with a remainder of 470.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 801 from 1271 and we're left with 470.
Grab the next digit (4) from the dividend, add it to 470, then carry on: 4704 / 801

Let's proceed to step 5:
If we divide 4704 by 801, we get 5 and a remainder of 699.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 4005 away from 4704, we end up with 699.
Append the next digit (5) from the dividend to 699 and continue with: 6995 / 801

Going ahead to step 6:
6995 divided by 801 is 8 with a remainder of 587.
Put 8 as the next digit of the answer. 
Result so far: 158.0
If we subtract 6408 from 6995, we get 587.
Bring next digit (2) of the dividend behind the 587 and repeat the process: 5872 / 801

Step 7:
801 can be fit into 5872 7 times, resulting in a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 1587.0
The remainder is 265 after subtracting 5607 from 5872.
Bring next digit (8) of the dividend behind the 265 and repeat the process: 2658 / 801

On to step 8:
The number 801 fits into 2658 3 times, leaving a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 15873.0
The remainder is 255 after subtracting 2403 from 2658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 9:
The number 801 fits into 2550 3 times, leaving a remainder of 147.
Put 3 as the next digit of the answer. 
Result so far: 15873.3
Subtracting 2403 from 2550 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 10:
The number 801 fits into 1470 1 times, leaving a remainder of 669.
Record the quotient 1 as the next digit in the result. 
Result so far: 15873.31
If we subtract 801 from 1470, we get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Step 11:
801 can be fit into 6690 8 times, resulting in a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 15873.318
If we take 6408 away from 6690, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 12:
801 goes into 2820 3 times with a remainder of 417.
The next digit of our result is 3. 
Result so far: 15873.3183
Subtracting 2403 from 2820 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 13:
801 goes into 4170 5 times with a remainder of 165.
The next digit of our result is 5. 
Result so far: 15873.31835
If we take 4005 away from 4170, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 14:
When dividing 1650 by 801, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 15873.318352
The remainder is 48 after subtracting 1602 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 15:
If we divide 480 by 801, we get 0 and a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 15873.318352
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
4800 divided by 801 is 5 with a remainder of 795.
Write down 5 as next digit of the result. 
Result so far: 15873.31835205
If we subtract 4005 from 4800, we get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Our division results in 15873.31835205 with a remaining 7.95e-07.
