16176093 divided by 819 
The aim is to understand the frequency of 819 in 16176093.

Let's proceed to step 1:
819 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 819

Advancing to step 2:
16 divided by 819 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 819

Step 3:
If we divide 161 by 819, we get 0 and a remainder of 161.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 161 and we're left with 161.
Grab the next digit (7) from the dividend, add it to 161, then carry on: 1617 / 819

On to step 4:
819 can be fit into 1617 1 times, resulting in a remainder of 798.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 798 after subtracting 819 from 1617.
Bring next digit (6) of the dividend behind the 798 and repeat the process: 7986 / 819

Advancing to step 5:
819 goes into 7986 9 times with a remainder of 615.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 7371 from 7986 and we're left with 615.
Take the next digit (0) from the dividend and append it to 615, then repeat: 6150 / 819

Going ahead to step 6:
819 can be fit into 6150 7 times, resulting in a remainder of 417.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
If we take 5733 away from 6150, we end up with 417.
Fetch the next digit (9) from the dividend, attach it to 417 and continue: 4179 / 819

On to step 7:
819 goes into 4179 5 times with a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 1975.0
If we take 4095 away from 4179, we end up with 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 819

Advancing to step 8:
If we divide 843 by 819, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 19751.0
If we take 819 away from 843, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 819 fits into 240 0 times, leaving a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 19751.0
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 10:
The number 819 fits into 2400 2 times, leaving a remainder of 762.
Write down 2 as next digit of the result. 
Result so far: 19751.02
Subtract 1638 from 2400 to get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Moving on to step 11:
819 can be fit into 7620 9 times, resulting in a remainder of 249.
Use 9 as the next digit of our solution. 
Result so far: 19751.029
Subtracting 7371 from 7620 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 12:
When dividing 2490 by 819, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 19751.0293
If we subtract 2457 from 2490, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
819 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 19751.0293
Subtract 0 from 330 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
When dividing 3300 by 819, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 19751.029304
Subtracting 3276 from 3300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 15:
819 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 19751.029304
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
819 can be fit into 2400 2 times, resulting in a remainder of 762.
Use 2 as the next digit of our solution. 
Result so far: 19751.02930402
Subtract 1638 from 2400 to get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

After the division, we end up with 19751.02930402 and a remainder of 7.62e-07.
