Let's divide 1396249 by 905
The aim is to understand the frequency of 905 in 1396249.

Going ahead to step 1:
1 divided by 905 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 905

Let's proceed to step 2:
905 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 905

On to step 3:
If we divide 139 by 905, we get 0 and a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 139 and we're left with 139.
Take the next digit (6) from the dividend and append it to 139, then repeat: 1396 / 905

Moving on to step 4:
If we divide 1396 by 905, we get 1 and a remainder of 491.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 905 from 1396 and we're left with 491.
Take the next digit (2) from the dividend and append it to 491, then repeat: 4912 / 905

Step 5:
The number 905 fits into 4912 5 times, leaving a remainder of 387.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 4525 from 4912 to get 387.
Bring next digit (4) of the dividend behind the 387 and repeat the process: 3874 / 905

Moving on to step 6:
The number 905 fits into 3874 4 times, leaving a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 3620 from 3874, we get 254.
Include the next digit (9) from the dividend after 254, then repeat: 2549 / 905

Going ahead to step 7:
The number 905 fits into 2549 2 times, leaving a remainder of 739.
Write down 2 as next digit of the result. 
Result so far: 1542.0
If we subtract 1810 from 2549, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Going ahead to step 8:
905 can be fit into 7390 8 times, resulting in a remainder of 150.
Record the quotient 8 as the next digit in the result. 
Result so far: 1542.8
Subtracting 7240 from 7390 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
When dividing 1500 by 905, we get 1 with a remainder of 595.
Record the quotient 1 as the next digit in the result. 
Result so far: 1542.81
If we take 905 away from 1500, we end up with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Going ahead to step 10:
If we divide 5950 by 905, we get 6 and a remainder of 520.
Put 6 as the next digit of the answer. 
Result so far: 1542.816
Subtracting 5430 from 5950 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 11:
905 can be fit into 5200 5 times, resulting in a remainder of 675.
Write down 5 as next digit of the result. 
Result so far: 1542.8165
Subtracting 4525 from 5200 leaves us with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 12:
6750 divided by 905 is 7 with a remainder of 415.
Put 7 as the next digit of the answer. 
Result so far: 1542.81657
The remainder is 415 after subtracting 6335 from 6750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 13:
If we divide 4150 by 905, we get 4 and a remainder of 530.
Write down 4 as next digit of the result. 
Result so far: 1542.816574
If we subtract 3620 from 4150, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Let's proceed to step 14:
The number 905 fits into 5300 5 times, leaving a remainder of 775.
The next digit of our result is 5. 
Result so far: 1542.8165745
The remainder is 775 after subtracting 4525 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 15:
905 goes into 7750 8 times with a remainder of 510.
The number 8 becomes the next digit in our result. 
Result so far: 1542.81657458
If we subtract 7240 from 7750, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Our division results in 1542.81657458 with a remaining 5.1e-07.
