99106776 ÷ 819 
The aim is to understand the frequency of 819 in 99106776.

On to step 1:
The number 819 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 819

Step 2:
819 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 819

Going ahead to step 3:
The number 819 fits into 991 1 times, leaving a remainder of 172.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 172 after subtracting 819 from 991.
Bring next digit (0) of the dividend behind the 172 and repeat the process: 1720 / 819

Advancing to step 4:
When dividing 1720 by 819, we get 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1638 from 1720 to get 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 819

On to step 5:
819 can be fit into 826 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 121.0
Deduct 819 from 826 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 819

Let's proceed to step 6:
If we divide 77 by 819, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 1210.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 819

Let's proceed to step 7:
777 divided by 819 is 0 with a remainder of 777.
The next digit of our result is 0. 
Result so far: 12100.0
If we take 0 away from 777, we end up with 777.
Include the next digit (6) from the dividend after 777, then repeat: 7776 / 819

Advancing to step 8:
819 goes into 7776 9 times with a remainder of 405.
Write down 9 as next digit of the result. 
Result so far: 121009.0
If we take 7371 away from 7776, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 9:
819 can be fit into 4050 4 times, resulting in a remainder of 774.
Put 4 as the next digit of the answer. 
Result so far: 121009.4
If we subtract 3276 from 4050, 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.

On to step 10:
When dividing 7740 by 819, we get 9 with a remainder of 369.
Write down 9 as next digit of the result. 
Result so far: 121009.49
If we subtract 7371 from 7740, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 11:
When dividing 3690 by 819, we get 4 with a remainder of 414.
Put 4 as the next digit of the answer. 
Result so far: 121009.494
Subtracting 3276 from 3690 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 12:
When dividing 4140 by 819, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 121009.4945
The remainder is 45 after subtracting 4095 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
819 goes into 450 0 times with a remainder of 450.
The next digit of our result is 0. 
Result so far: 121009.4945
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 14:
If we divide 4500 by 819, we get 5 and a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 121009.494505
Subtract 4095 from 4500 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 15:
If we divide 4050 by 819, we get 4 and a remainder of 774.
The number 4 becomes the next digit in our result. 
Result so far: 121009.4945054
Subtracting 3276 from 4050 leaves us with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Going ahead to step 16:
819 can be fit into 7740 9 times, resulting in a remainder of 369.
Use 9 as the next digit of our solution. 
Result so far: 121009.49450549
If we subtract 7371 from 7740, we get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The quotient of the division is 121009.49450549, and the remainder is 3.69e-07.
