10049864 ÷ 819 
The aim is to understand the frequency of 819 in 10049864.

On to step 1:
When dividing 1 by 819, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 819

Going ahead to step 2:
If we divide 10 by 819, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 819

Going ahead to step 3:
If we divide 100 by 819, we get 0 and a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 100 leaves us with 100.
Bring next digit (4) of the dividend behind the 100 and repeat the process: 1004 / 819

Step 4:
819 can be fit into 1004 1 times, resulting in a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 819 from 1004, we get 185.
Bring next digit (9) of the dividend behind the 185 and repeat the process: 1859 / 819

On to step 5:
If we divide 1859 by 819, we get 2 and a remainder of 221.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 1638 from 1859 leaves us with 221.
Fetch the next digit (8) from the dividend, attach it to 221 and continue: 2218 / 819

Advancing to step 6:
The number 819 fits into 2218 2 times, leaving a remainder of 580.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 1638 from 2218 and we're left with 580.
Include the next digit (6) from the dividend after 580, then repeat: 5806 / 819

Step 7:
If we divide 5806 by 819, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 1227.0
If we take 5733 away from 5806, we end up with 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 819

Moving on to step 8:
819 can be fit into 734 0 times, resulting in a remainder of 734.
Write down 0 as next digit of the result. 
Result so far: 12270.0
Deduct 0 from 734 and we're left with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Step 9:
When dividing 7340 by 819, we get 8 with a remainder of 788.
Record the quotient 8 as the next digit in the result. 
Result so far: 12270.8
Deduct 6552 from 7340 and we're left with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Let's proceed to step 10:
When dividing 7880 by 819, we get 9 with a remainder of 509.
The number 9 becomes the next digit in our result. 
Result so far: 12270.89
The remainder is 509 after subtracting 7371 from 7880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

On to step 11:
819 goes into 5090 6 times with a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 12270.896
If we take 4914 away from 5090, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 12:
1760 divided by 819 is 2 with a remainder of 122.
Record the quotient 2 as the next digit in the result. 
Result so far: 12270.8962
If we take 1638 away from 1760, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
819 goes into 1220 1 times with a remainder of 401.
Record the quotient 1 as the next digit in the result. 
Result so far: 12270.89621
Subtract 819 from 1220 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 14:
4010 divided by 819 is 4 with a remainder of 734.
The next digit of our result is 4. 
Result so far: 12270.896214
If we take 3276 away from 4010, we end up with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Let's proceed to step 15:
7340 divided by 819 is 8 with a remainder of 788.
Record the quotient 8 as the next digit in the result. 
Result so far: 12270.8962148
Subtracting 6552 from 7340 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 16:
When dividing 7880 by 819, we get 9 with a remainder of 509.
Put 9 as the next digit of the answer. 
Result so far: 12270.89621489
Subtract 7371 from 7880 to get 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

The final outcome is 12270.89621489, with a leftover of 5.09e-07.
