We're dividing 72368454 by 890 
The aim is to understand the frequency of 890 in 72368454.

Step 1:
The number 890 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 890

Let's proceed to step 2:
72 divided by 890 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 890

Step 3:
If we divide 723 by 890, we get 0 and a remainder of 723.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 723 to get 723.
Fetch the next digit (6) from the dividend, attach it to 723 and continue: 7236 / 890

Step 4:
890 can be fit into 7236 8 times, resulting in a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7120 away from 7236, we end up with 116.
Fetch the next digit (8) from the dividend, attach it to 116 and continue: 1168 / 890

Moving on to step 5:
The number 890 fits into 1168 1 times, leaving a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 890 from 1168, we get 278.
Grab the next digit (4) from the dividend, add it to 278, then carry on: 2784 / 890

On to step 6:
If we divide 2784 by 890, we get 3 and a remainder of 114.
Put 3 as the next digit of the answer. 
Result so far: 813.0
If we subtract 2670 from 2784, we get 114.
Grab the next digit (5) from the dividend, add it to 114, then carry on: 1145 / 890

On to step 7:
When dividing 1145 by 890, we get 1 with a remainder of 255.
Put 1 as the next digit of the answer. 
Result so far: 8131.0
If we subtract 890 from 1145, we get 255.
Include the next digit (4) from the dividend after 255, then repeat: 2554 / 890

Advancing to step 8:
The number 890 fits into 2554 2 times, leaving a remainder of 774.
Use 2 as the next digit of our solution. 
Result so far: 81312.0
If we subtract 1780 from 2554, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Step 9:
7740 divided by 890 is 8 with a remainder of 620.
Put 8 as the next digit of the answer. 
Result so far: 81312.8
If we take 7120 away from 7740, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
When dividing 6200 by 890, we get 6 with a remainder of 860.
Write down 6 as next digit of the result. 
Result so far: 81312.86
If we take 5340 away from 6200, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Advancing to step 11:
890 goes into 8600 9 times with a remainder of 590.
Use 9 as the next digit of our solution. 
Result so far: 81312.869
The remainder is 590 after subtracting 8010 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 12:
The number 890 fits into 5900 6 times, leaving a remainder of 560.
The number 6 becomes the next digit in our result. 
Result so far: 81312.8696
Subtract 5340 from 5900 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
If we divide 5600 by 890, we get 6 and a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 81312.86966
Subtract 5340 from 5600 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 81312.86966, with a leftover of 0.00026.
