45173580 ÷ 403 
The aim is to understand the frequency of 403 in 45173580.

Let's proceed to step 1:
When dividing 4 by 403, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 403

Going ahead to step 2:
403 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 403

Step 3:
451 divided by 403 is 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 403 from 451, we get 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 403

Let's proceed to step 4:
403 can be fit into 487 1 times, resulting in a remainder of 84.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 84 after subtracting 403 from 487.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 403

Going ahead to step 5:
The number 403 fits into 843 2 times, leaving a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 806 from 843, we get 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 403

On to step 6:
375 divided by 403 is 0 with a remainder of 375.
Use 0 as the next digit of our solution. 
Result so far: 1120.0
If we take 0 away from 375, we end up with 375.
Include the next digit (8) from the dividend after 375, then repeat: 3758 / 403

Let's proceed to step 7:
The number 403 fits into 3758 9 times, leaving a remainder of 131.
Write down 9 as next digit of the result. 
Result so far: 11209.0
If we take 3627 away from 3758, we end up with 131.
Take the next digit (0) from the dividend and append it to 131, then repeat: 1310 / 403

Moving on to step 8:
If we divide 1310 by 403, we get 3 and a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 112093.0
If we subtract 1209 from 1310, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
1010 divided by 403 is 2 with a remainder of 204.
The next digit of our result is 2. 
Result so far: 112093.2
Subtract 806 from 1010 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 10:
403 goes into 2040 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 112093.25
Subtract 2015 from 2040 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
403 goes into 250 0 times with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 112093.25
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 12:
403 can be fit into 2500 6 times, resulting in a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 112093.2506
If we take 2418 away from 2500, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 13:
403 can be fit into 820 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 112093.25062
If we subtract 806 from 820, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 14:
403 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 112093.25062
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
When dividing 1400 by 403, we get 3 with a remainder of 191.
Record the quotient 3 as the next digit in the result. 
Result so far: 112093.2506203
If we take 1209 away from 1400, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 16:
If we divide 1910 by 403, we get 4 and a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 112093.25062034
Subtracting 1612 from 1910 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

In conclusion, the division gives 112093.25062034 with a balance of 2.98e-07.
