Let's divide 49123640 by 403
The aim is to understand the frequency of 403 in 49123640.

On to step 1:
If we divide 4 by 403, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 403

Moving on to step 2:
49 divided by 403 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 403

Step 3:
403 goes into 491 1 times with a remainder of 88.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 403 from 491 leaves us with 88.
Bring next digit (2) of the dividend behind the 88 and repeat the process: 882 / 403

Moving on to step 4:
403 goes into 882 2 times with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 806 from 882 to get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 403

On to step 5:
403 goes into 763 1 times with a remainder of 360.
The next digit of our result is 1. 
Result so far: 121.0
Subtract 403 from 763 to get 360.
Include the next digit (6) from the dividend after 360, then repeat: 3606 / 403

Going ahead to step 6:
The number 403 fits into 3606 8 times, leaving a remainder of 382.
Record the quotient 8 as the next digit in the result. 
Result so far: 1218.0
Subtract 3224 from 3606 to get 382.
Grab the next digit (4) from the dividend, add it to 382, then carry on: 3824 / 403

Let's proceed to step 7:
If we divide 3824 by 403, we get 9 and a remainder of 197.
Use 9 as the next digit of our solution. 
Result so far: 12189.0
Deduct 3627 from 3824 and we're left with 197.
Take the next digit (0) from the dividend and append it to 197, then repeat: 1970 / 403

Step 8:
If we divide 1970 by 403, we get 4 and a remainder of 358.
Record the quotient 4 as the next digit in the result. 
Result so far: 121894.0
The remainder is 358 after subtracting 1612 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 9:
403 can be fit into 3580 8 times, resulting in a remainder of 356.
Use 8 as the next digit of our solution. 
Result so far: 121894.8
If we take 3224 away from 3580, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 10:
When dividing 3560 by 403, we get 8 with a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 121894.88
Subtracting 3224 from 3560 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 121894.88 with a remainder of 0.336.
