17074953 ÷ 903 
The aim is to understand the frequency of 903 in 17074953.

Advancing to step 1:
903 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 903

Going ahead to step 2:
17 divided by 903 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 903

Advancing to step 3:
When dividing 170 by 903, we get 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 170, we get 170.
Grab the next digit (7) from the dividend, add it to 170, then carry on: 1707 / 903

Advancing to step 4:
When dividing 1707 by 903, we get 1 with a remainder of 804.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 903 from 1707 to get 804.
Take the next digit (4) from the dividend and append it to 804, then repeat: 8044 / 903

Moving on to step 5:
The number 903 fits into 8044 8 times, leaving a remainder of 820.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 7224 from 8044 to get 820.
Fetch the next digit (9) from the dividend, attach it to 820 and continue: 8209 / 903

Advancing to step 6:
If we divide 8209 by 903, we get 9 and a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
If we subtract 8127 from 8209, we get 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 903

Advancing to step 7:
When dividing 825 by 903, we get 0 with a remainder of 825.
The next digit of our result is 0. 
Result so far: 1890.0
The remainder is 825 after subtracting 0 from 825.
Include the next digit (3) from the dividend after 825, then repeat: 8253 / 903

Let's proceed to step 8:
When dividing 8253 by 903, we get 9 with a remainder of 126.
The next digit of our result is 9. 
Result so far: 18909.0
Subtract 8127 from 8253 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
When dividing 1260 by 903, we get 1 with a remainder of 357.
Record the quotient 1 as the next digit in the result. 
Result so far: 18909.1
If we subtract 903 from 1260, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 10:
If we divide 3570 by 903, we get 3 and a remainder of 861.
Record the quotient 3 as the next digit in the result. 
Result so far: 18909.13
Deduct 2709 from 3570 and we're left with 861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8610, and continue the process.

Moving on to step 11:
903 goes into 8610 9 times with a remainder of 483.
The number 9 becomes the next digit in our result. 
Result so far: 18909.139
Subtracting 8127 from 8610 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

On to step 12:
The number 903 fits into 4830 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 18909.1395
Deduct 4515 from 4830 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Let's proceed to step 13:
When dividing 3150 by 903, we get 3 with a remainder of 441.
The next digit of our result is 3. 
Result so far: 18909.13953
Subtracting 2709 from 3150 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Let's proceed to step 14:
903 goes into 4410 4 times with a remainder of 798.
Write down 4 as next digit of the result. 
Result so far: 18909.139534
Deduct 3612 from 4410 and we're left with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

On to step 15:
903 can be fit into 7980 8 times, resulting in a remainder of 756.
Write down 8 as next digit of the result. 
Result so far: 18909.1395348
Subtract 7224 from 7980 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Let's proceed to step 16:
When dividing 7560 by 903, we get 8 with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 18909.13953488
If we take 7224 away from 7560, we end up 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 outcome is 18909.13953488, with a leftover of 3.36e-07.
