19230030 ÷ 851 
The aim is to understand the frequency of 851 in 19230030.

On to step 1:
When dividing 1 by 851, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 851

Going ahead to step 2:
If we divide 19 by 851, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 851

Going ahead to step 3:
851 goes into 192 0 times with a remainder of 192.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 192, we get 192.
Append the next digit (3) from the dividend to 192 and continue with: 1923 / 851

Advancing to step 4:
851 goes into 1923 2 times with a remainder of 221.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1702 from 1923 to get 221.
Include the next digit (0) from the dividend after 221, then repeat: 2210 / 851

Going ahead to step 5:
If we divide 2210 by 851, we get 2 and a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 1702 from 2210, we get 508.
Include the next digit (0) from the dividend after 508, then repeat: 5080 / 851

Going ahead to step 6:
When dividing 5080 by 851, we get 5 with a remainder of 825.
The next digit of our result is 5. 
Result so far: 225.0
The remainder is 825 after subtracting 4255 from 5080.
Grab the next digit (3) from the dividend, add it to 825, then carry on: 8253 / 851

Going ahead to step 7:
851 can be fit into 8253 9 times, resulting in a remainder of 594.
The number 9 becomes the next digit in our result. 
Result so far: 2259.0
The remainder is 594 after subtracting 7659 from 8253.
Fetch the next digit (0) from the dividend, attach it to 594 and continue: 5940 / 851

Moving on to step 8:
The number 851 fits into 5940 6 times, leaving a remainder of 834.
Record the quotient 6 as the next digit in the result. 
Result so far: 22596.0
If we subtract 5106 from 5940, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Step 9:
8340 divided by 851 is 9 with a remainder of 681.
The next digit of our result is 9. 
Result so far: 22596.9
Subtracting 7659 from 8340 leaves us with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Let's proceed to step 10:
If we divide 6810 by 851, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 22596.98
If we subtract 6808 from 6810, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 851 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 22596.98
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
200 divided by 851 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 22596.98
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 22596.98 and a remainder of 0.002.
