We look at the division of 81751624 by 302 
The aim is to understand the frequency of 302 in 81751624.

Advancing to step 1:
302 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 302

Advancing to step 2:
If we divide 81 by 302, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 302

Let's proceed to step 3:
817 divided by 302 is 2 with a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 604 away from 817, we end up with 213.
Append the next digit (5) from the dividend to 213 and continue with: 2135 / 302

Let's proceed to step 4:
2135 divided by 302 is 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 2114 from 2135 leaves us with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 302

Step 5:
The number 302 fits into 211 0 times, leaving a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 270.0
Deduct 0 from 211 and we're left with 211.
Append the next digit (6) from the dividend to 211 and continue with: 2116 / 302

Going ahead to step 6:
If we divide 2116 by 302, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 2707.0
If we subtract 2114 from 2116, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 302

Moving on to step 7:
The number 302 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 27070.0
Subtract 0 from 22 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 302

Moving on to step 8:
If we divide 224 by 302, we get 0 and a remainder of 224.
The number 0 becomes the next digit in our result. 
Result so far: 270700.0
If we take 0 away from 224, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 9:
2240 divided by 302 is 7 with a remainder of 126.
Record the quotient 7 as the next digit in the result. 
Result so far: 270700.7
If we take 2114 away from 2240, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
302 can be fit into 1260 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 270700.74
Subtracting 1208 from 1260 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
The number 302 fits into 520 1 times, leaving a remainder of 218.
The next digit of our result is 1. 
Result so far: 270700.741
If we subtract 302 from 520, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 12:
The number 302 fits into 2180 7 times, leaving a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 270700.7417
Deduct 2114 from 2180 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
The number 302 fits into 660 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 270700.74172
The remainder is 56 after subtracting 604 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 14:
302 can be fit into 560 1 times, resulting in a remainder of 258.
The number 1 becomes the next digit in our result. 
Result so far: 270700.741721
The remainder is 258 after subtracting 302 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 15:
When dividing 2580 by 302, we get 8 with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 270700.7417218
Subtracting 2416 from 2580 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 16:
302 can be fit into 1640 5 times, resulting in a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 270700.74172185
If we subtract 1510 from 1640, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 270700.74172185, with a leftover of 1.3e-07.
