Let's divide 72586407 by 105
The aim is to understand the frequency of 105 in 72586407.

On to step 1:
105 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 105

Moving on to step 2:
When dividing 72 by 105, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Append the next digit (5) from the dividend to 72 and continue with: 725 / 105

Moving on to step 3:
If we divide 725 by 105, we get 6 and a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 630 away from 725, we end up with 95.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 105

Going ahead to step 4:
105 can be fit into 958 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 945 from 958 leaves us with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 105

Going ahead to step 5:
105 can be fit into 136 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 691.0
Subtract 105 from 136 to get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 105

Step 6:
The number 105 fits into 314 2 times, leaving a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 6912.0
The remainder is 104 after subtracting 210 from 314.
Fetch the next digit (0) from the dividend, attach it to 104 and continue: 1040 / 105

Let's proceed to step 7:
105 goes into 1040 9 times with a remainder of 95.
The next digit of our result is 9. 
Result so far: 69129.0
Subtract 945 from 1040 to get 95.
Grab the next digit (7) from the dividend, add it to 95, then carry on: 957 / 105

Step 8:
If we divide 957 by 105, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 691299.0
Subtract 945 from 957 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
105 can be fit into 120 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 691299.1
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
105 goes into 150 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 691299.11
If we take 105 away from 150, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 691299.11, and the remainder is 0.045.
