903863 divided by 73 
The aim is to understand the frequency of 73 in 903863.

On to step 1:
When dividing 9 by 73, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 73

Let's proceed to step 2:
When dividing 90 by 73, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 73 from 90 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 73

Step 3:
When dividing 173 by 73, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 146 from 173 to get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 73

Let's proceed to step 4:
When dividing 278 by 73, we get 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 219 from 278 leaves us with 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 73

Step 5:
73 can be fit into 596 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1238.0
If we take 584 away from 596, we end up with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 73

On to step 6:
73 can be fit into 123 1 times, resulting in a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 12381.0
The remainder is 50 after subtracting 73 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
If we divide 500 by 73, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 12381.6
Subtract 438 from 500 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
73 can be fit into 620 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 12381.68
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 73, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 12381.684
The remainder is 68 after subtracting 292 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
680 divided by 73 is 9 with a remainder of 23.
The next digit of our result is 9. 
Result so far: 12381.6849
Deduct 657 from 680 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
When dividing 230 by 73, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 12381.68493
Subtracting 219 from 230 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 12381.684931
Deduct 73 from 110 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
The number 73 fits into 370 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 12381.6849315
Subtract 365 from 370 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.

Let's proceed to step 14:
73 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 12381.6849315
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 12381.6849315, and the remainder is 5e-08.
