We're dividing 43057294 by 903 
The aim is to understand the frequency of 903 in 43057294.

Moving on to step 1:
The number 903 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 903

Moving on to step 2:
43 divided by 903 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 903

Advancing to step 3:
903 goes into 430 0 times with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 430 leaves us with 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 903

Advancing to step 4:
If we divide 4305 by 903, we get 4 and a remainder of 693.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3612 from 4305 and we're left with 693.
Append the next digit (7) from the dividend to 693 and continue with: 6937 / 903

On to step 5:
The number 903 fits into 6937 7 times, leaving a remainder of 616.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 6321 from 6937 and we're left with 616.
Append the next digit (2) from the dividend to 616 and continue with: 6162 / 903

Going ahead to step 6:
When dividing 6162 by 903, we get 6 with a remainder of 744.
Write down 6 as next digit of the result. 
Result so far: 476.0
If we take 5418 away from 6162, we end up with 744.
Take the next digit (9) from the dividend and append it to 744, then repeat: 7449 / 903

Advancing to step 7:
When dividing 7449 by 903, we get 8 with a remainder of 225.
Record the quotient 8 as the next digit in the result. 
Result so far: 4768.0
Subtract 7224 from 7449 to get 225.
Bring next digit (4) of the dividend behind the 225 and repeat the process: 2254 / 903

On to step 8:
903 goes into 2254 2 times with a remainder of 448.
The next digit of our result is 2. 
Result so far: 47682.0
If we take 1806 away from 2254, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 9:
903 goes into 4480 4 times with a remainder of 868.
The next digit of our result is 4. 
Result so far: 47682.4
Subtract 3612 from 4480 to get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Let's proceed to step 10:
903 goes into 8680 9 times with a remainder of 553.
Write down 9 as next digit of the result. 
Result so far: 47682.49
The remainder is 553 after subtracting 8127 from 8680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

On to step 11:
The number 903 fits into 5530 6 times, leaving a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 47682.496
Subtract 5418 from 5530 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
The number 903 fits into 1120 1 times, leaving a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 47682.4961
Subtract 903 from 1120 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 13:
903 can be fit into 2170 2 times, resulting in a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 47682.49612
Subtract 1806 from 2170 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 14:
When dividing 3640 by 903, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 47682.496124
Deduct 3612 from 3640 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 15:
If we divide 280 by 903, we get 0 and a remainder of 280.
The next digit of our result is 0. 
Result so far: 47682.496124
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
2800 divided by 903 is 3 with a remainder of 91.
The next digit of our result is 3. 
Result so far: 47682.49612403
Subtracting 2709 from 2800 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

After the division, we end up with 47682.49612403 and a remainder of 9.1e-08.
