We look at the division of 81348305 by 107 
The aim is to understand the frequency of 107 in 81348305.

On to step 1:
8 divided by 107 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 107

Let's proceed to step 2:
107 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 107

Moving on to step 3:
If we divide 813 by 107, we get 7 and a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 749 away from 813, we end up with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 107

Advancing to step 4:
107 can be fit into 644 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 642 from 644 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 107

Advancing to step 5:
107 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 760.0
If we subtract 0 from 28, we get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 107

Moving on to step 6:
If we divide 283 by 107, we get 2 and a remainder of 69.
Record the quotient 2 as the next digit in the result. 
Result so far: 7602.0
If we subtract 214 from 283, we get 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 107

Advancing to step 7:
690 divided by 107 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 76026.0
Subtracting 642 from 690 leaves us with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 107

Moving on to step 8:
The number 107 fits into 485 4 times, leaving a remainder of 57.
The next digit of our result is 4. 
Result so far: 760264.0
The remainder is 57 after subtracting 428 from 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
107 can be fit into 570 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 760264.5
Subtracting 535 from 570 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
107 can be fit into 350 3 times, resulting in a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 760264.53
Subtract 321 from 350 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
107 can be fit into 290 2 times, resulting in a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 760264.532
If we take 214 away from 290, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
107 goes into 760 7 times with a remainder of 11.
The next digit of our result is 7. 
Result so far: 760264.5327
If we subtract 749 from 760, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
110 divided by 107 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 760264.53271
Deduct 107 from 110 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
The number 107 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 760264.53271
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
107 can be fit into 300 2 times, resulting in a remainder of 86.
The number 2 becomes the next digit in our result. 
Result so far: 760264.5327102
Subtracting 214 from 300 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 16:
860 divided by 107 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 760264.53271028
Subtracting 856 from 860 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 760264.53271028 with a remainder of 4e-09.
