15450079 ÷ 904 
The aim is to understand the frequency of 904 in 15450079.

Step 1:
The number 904 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 904

Moving on to step 2:
When dividing 15 by 904, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 904

Let's proceed to step 3:
The number 904 fits into 154 0 times, leaving a remainder of 154.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Include the next digit (5) from the dividend after 154, then repeat: 1545 / 904

Step 4:
When dividing 1545 by 904, we get 1 with a remainder of 641.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 904 from 1545 and we're left with 641.
Append the next digit (0) from the dividend to 641 and continue with: 6410 / 904

Step 5:
When dividing 6410 by 904, we get 7 with a remainder of 82.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 6328 from 6410 leaves us with 82.
Fetch the next digit (0) from the dividend, attach it to 82 and continue: 820 / 904

On to step 6:
820 divided by 904 is 0 with a remainder of 820.
Write down 0 as next digit of the result. 
Result so far: 170.0
Deduct 0 from 820 and we're left with 820.
Bring next digit (7) of the dividend behind the 820 and repeat the process: 8207 / 904

Let's proceed to step 7:
The number 904 fits into 8207 9 times, leaving a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 1709.0
If we take 8136 away from 8207, we end up with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 904

Advancing to step 8:
904 can be fit into 719 0 times, resulting in a remainder of 719.
Use 0 as the next digit of our solution. 
Result so far: 17090.0
Subtracting 0 from 719 leaves us with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Let's proceed to step 9:
If we divide 7190 by 904, we get 7 and a remainder of 862.
Use 7 as the next digit of our solution. 
Result so far: 17090.7
If we take 6328 away from 7190, we end up with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Moving on to step 10:
If we divide 8620 by 904, we get 9 and a remainder of 484.
The number 9 becomes the next digit in our result. 
Result so far: 17090.79
The remainder is 484 after subtracting 8136 from 8620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 11:
If we divide 4840 by 904, we get 5 and a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 17090.795
Subtract 4520 from 4840 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
904 can be fit into 3200 3 times, resulting in a remainder of 488.
Write down 3 as next digit of the result. 
Result so far: 17090.7953
Subtract 2712 from 3200 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Moving on to step 13:
904 can be fit into 4880 5 times, resulting in a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 17090.79535
Subtracting 4520 from 4880 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 14:
904 goes into 3600 3 times with a remainder of 888.
The next digit of our result is 3. 
Result so far: 17090.795353
The remainder is 888 after subtracting 2712 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Advancing to step 15:
904 can be fit into 8880 9 times, resulting in a remainder of 744.
Use 9 as the next digit of our solution. 
Result so far: 17090.7953539
If we subtract 8136 from 8880, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 16:
904 can be fit into 7440 8 times, resulting in a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 17090.79535398
Subtracting 7232 from 7440 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The quotient of the division is 17090.79535398, and the remainder is 2.08e-07.
