17770020 divided by 816 
The aim is to understand the frequency of 816 in 17770020.

Going ahead to step 1:
816 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 816

Step 2:
When dividing 17 by 816, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 816

Let's proceed to step 3:
When dividing 177 by 816, we get 0 with a remainder of 177.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 177 to get 177.
Grab the next digit (7) from the dividend, add it to 177, then carry on: 1777 / 816

Going ahead to step 4:
When dividing 1777 by 816, we get 2 with a remainder of 145.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1632 from 1777 to get 145.
Bring next digit (0) of the dividend behind the 145 and repeat the process: 1450 / 816

Moving on to step 5:
816 goes into 1450 1 times with a remainder of 634.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 816 from 1450 leaves us with 634.
Bring next digit (0) of the dividend behind the 634 and repeat the process: 6340 / 816

Advancing to step 6:
6340 divided by 816 is 7 with a remainder of 628.
Use 7 as the next digit of our solution. 
Result so far: 217.0
The remainder is 628 after subtracting 5712 from 6340.
Take the next digit (2) from the dividend and append it to 628, then repeat: 6282 / 816

Step 7:
6282 divided by 816 is 7 with a remainder of 570.
Put 7 as the next digit of the answer. 
Result so far: 2177.0
Subtracting 5712 from 6282 leaves us with 570.
Grab the next digit (0) from the dividend, add it to 570, then carry on: 5700 / 816

Let's proceed to step 8:
If we divide 5700 by 816, we get 6 and a remainder of 804.
Use 6 as the next digit of our solution. 
Result so far: 21776.0
If we take 4896 away from 5700, we end up with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

On to step 9:
8040 divided by 816 is 9 with a remainder of 696.
The number 9 becomes the next digit in our result. 
Result so far: 21776.9
If we take 7344 away from 8040, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 10:
6960 divided by 816 is 8 with a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 21776.98
The remainder is 432 after subtracting 6528 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Advancing to step 11:
When dividing 4320 by 816, we get 5 with a remainder of 240.
Record the quotient 5 as the next digit in the result. 
Result so far: 21776.985
If we subtract 4080 from 4320, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
The number 816 fits into 2400 2 times, leaving a remainder of 768.
Put 2 as the next digit of the answer. 
Result so far: 21776.9852
If we subtract 1632 from 2400, we get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Let's proceed to step 13:
7680 divided by 816 is 9 with a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 21776.98529
Subtract 7344 from 7680 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 14:
816 can be fit into 3360 4 times, resulting in a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 21776.985294
The remainder is 96 after subtracting 3264 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
816 can be fit into 960 1 times, resulting in a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 21776.9852941
If we subtract 816 from 960, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 16:
816 can be fit into 1440 1 times, resulting in a remainder of 624.
Record the quotient 1 as the next digit in the result. 
Result so far: 21776.98529411
The remainder is 624 after subtracting 816 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Our division results in 21776.98529411 with a remaining 6.24e-07.
