We divide 16225554 by 819
The aim is to understand the frequency of 819 in 16225554.

Advancing to step 1:
819 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 819

Going ahead to step 2:
When dividing 16 by 819, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 819

Step 3:
819 can be fit into 162 0 times, resulting in a remainder of 162.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 162, we end up with 162.
Include the next digit (2) from the dividend after 162, then repeat: 1622 / 819

Advancing to step 4:
819 can be fit into 1622 1 times, resulting in a remainder of 803.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 819 away from 1622, we end up with 803.
Fetch the next digit (5) from the dividend, attach it to 803 and continue: 8035 / 819

Advancing to step 5:
The number 819 fits into 8035 9 times, leaving a remainder of 664.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 7371 from 8035 leaves us with 664.
Append the next digit (5) from the dividend to 664 and continue with: 6645 / 819

Step 6:
The number 819 fits into 6645 8 times, leaving a remainder of 93.
The next digit of our result is 8. 
Result so far: 198.0
Deduct 6552 from 6645 and we're left with 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 819

Advancing to step 7:
The number 819 fits into 935 1 times, leaving a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 1981.0
Subtract 819 from 935 to get 116.
Fetch the next digit (4) from the dividend, attach it to 116 and continue: 1164 / 819

Moving on to step 8:
If we divide 1164 by 819, we get 1 and a remainder of 345.
Write down 1 as next digit of the result. 
Result so far: 19811.0
Subtract 819 from 1164 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
When dividing 3450 by 819, we get 4 with a remainder of 174.
Record the quotient 4 as the next digit in the result. 
Result so far: 19811.4
Subtracting 3276 from 3450 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 10:
When dividing 1740 by 819, we get 2 with a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 19811.42
Subtract 1638 from 1740 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 11:
The number 819 fits into 1020 1 times, leaving a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 19811.421
If we take 819 away from 1020, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 12:
819 can be fit into 2010 2 times, resulting in a remainder of 372.
The next digit of our result is 2. 
Result so far: 19811.4212
Subtract 1638 from 2010 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 13:
819 can be fit into 3720 4 times, resulting in a remainder of 444.
Record the quotient 4 as the next digit in the result. 
Result so far: 19811.42124
Subtract 3276 from 3720 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 14:
4440 divided by 819 is 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 19811.421245
Subtracting 4095 from 4440 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 15:
If we divide 3450 by 819, we get 4 and a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 19811.4212454
If we take 3276 away from 3450, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 16:
The number 819 fits into 1740 2 times, leaving a remainder of 102.
Write down 2 as next digit of the result. 
Result so far: 19811.42124542
The remainder is 102 after subtracting 1638 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final result is 19811.42124542 with a remainder of 1.02e-07.
