13896533 divided by 905 
The aim is to understand the frequency of 905 in 13896533.

Advancing to step 1:
905 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 905

On to step 2:
905 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 905

Going ahead to step 3:
The number 905 fits into 138 0 times, leaving a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 905

Step 4:
1389 divided by 905 is 1 with a remainder of 484.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 905 away from 1389, we end up with 484.
Bring next digit (6) of the dividend behind the 484 and repeat the process: 4846 / 905

Let's proceed to step 5:
When dividing 4846 by 905, we get 5 with a remainder of 321.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 4525 from 4846 to get 321.
Grab the next digit (5) from the dividend, add it to 321, then carry on: 3215 / 905

Let's proceed to step 6:
3215 divided by 905 is 3 with a remainder of 500.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 500 after subtracting 2715 from 3215.
Grab the next digit (3) from the dividend, add it to 500, then carry on: 5003 / 905

On to step 7:
905 goes into 5003 5 times with a remainder of 478.
Use 5 as the next digit of our solution. 
Result so far: 1535.0
If we subtract 4525 from 5003, we get 478.
Grab the next digit (3) from the dividend, add it to 478, then carry on: 4783 / 905

Let's proceed to step 8:
905 can be fit into 4783 5 times, resulting in a remainder of 258.
Use 5 as the next digit of our solution. 
Result so far: 15355.0
Subtract 4525 from 4783 to get 258.
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 9:
The number 905 fits into 2580 2 times, leaving a remainder of 770.
Record the quotient 2 as the next digit in the result. 
Result so far: 15355.2
The remainder is 770 after subtracting 1810 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 10:
905 goes into 7700 8 times with a remainder of 460.
The number 8 becomes the next digit in our result. 
Result so far: 15355.28
If we subtract 7240 from 7700, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
When dividing 4600 by 905, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 15355.285
If we subtract 4525 from 4600, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
When dividing 750 by 905, we get 0 with a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 15355.285
Deduct 0 from 750 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 13:
7500 divided by 905 is 8 with a remainder of 260.
The next digit of our result is 8. 
Result so far: 15355.28508
If we take 7240 away from 7500, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 14:
905 can be fit into 2600 2 times, resulting in a remainder of 790.
Record the quotient 2 as the next digit in the result. 
Result so far: 15355.285082
If we take 1810 away from 2600, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 15:
The number 905 fits into 7900 8 times, leaving a remainder of 660.
Put 8 as the next digit of the answer. 
Result so far: 15355.2850828
If we take 7240 away from 7900, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 16:
When dividing 6600 by 905, we get 7 with a remainder of 265.
Write down 7 as next digit of the result. 
Result so far: 15355.28508287
The remainder is 265 after subtracting 6335 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final outcome is 15355.28508287, with a leftover of 2.65e-07.
