We look at the division of 10339649 by 915 
The aim is to understand the frequency of 915 in 10339649.

On to step 1:
If we divide 1 by 915, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 915

Moving on to step 2:
10 divided by 915 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 915

Going ahead to step 3:
The number 915 fits into 103 0 times, leaving a remainder of 103.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 103, we end up with 103.
Bring next digit (3) of the dividend behind the 103 and repeat the process: 1033 / 915

Going ahead to step 4:
The number 915 fits into 1033 1 times, leaving a remainder of 118.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 915 from 1033 and we're left with 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 915

Step 5:
1189 divided by 915 is 1 with a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 915 from 1189 to get 274.
Append the next digit (6) from the dividend to 274 and continue with: 2746 / 915

On to step 6:
When dividing 2746 by 915, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtracting 2745 from 2746 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 915

On to step 7:
The number 915 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 1130.0
If we subtract 0 from 14, we get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 915

Going ahead to step 8:
When dividing 149 by 915, we get 0 with a remainder of 149.
Use 0 as the next digit of our solution. 
Result so far: 11300.0
Deduct 0 from 149 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 9:
The number 915 fits into 1490 1 times, leaving a remainder of 575.
Write down 1 as next digit of the result. 
Result so far: 11300.1
If we take 915 away from 1490, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Going ahead to step 10:
915 goes into 5750 6 times with a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 11300.16
If we subtract 5490 from 5750, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
If we divide 2600 by 915, we get 2 and a remainder of 770.
Put 2 as the next digit of the answer. 
Result so far: 11300.162
If we take 1830 away from 2600, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 12:
915 goes into 7700 8 times with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 11300.1628
Subtract 7320 from 7700 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
3800 divided by 915 is 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 11300.16284
If we take 3660 away from 3800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
1400 divided by 915 is 1 with a remainder of 485.
The next digit of our result is 1. 
Result so far: 11300.162841
If we take 915 away from 1400, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 15:
915 can be fit into 4850 5 times, resulting in a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 11300.1628415
Subtracting 4575 from 4850 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 16:
If we divide 2750 by 915, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 11300.16284153
Subtract 2745 from 2750 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 11300.16284153 with a remainder of 5e-09.
