We divide 69630126 by 819
The aim is to understand the frequency of 819 in 69630126.

Moving on to step 1:
The number 819 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 819

Moving on to step 2:
The number 819 fits into 69 0 times, leaving a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 819

Going ahead to step 3:
The number 819 fits into 696 0 times, leaving a remainder of 696.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 696 after subtracting 0 from 696.
Fetch the next digit (3) from the dividend, attach it to 696 and continue: 6963 / 819

Step 4:
If we divide 6963 by 819, we get 8 and a remainder of 411.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6552 away from 6963, we end up with 411.
Bring next digit (0) of the dividend behind the 411 and repeat the process: 4110 / 819

Advancing to step 5:
If we divide 4110 by 819, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 4095 from 4110 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 819

Step 6:
If we divide 151 by 819, we get 0 and a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 850.0
Deduct 0 from 151 and we're left with 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 819

Let's proceed to step 7:
If we divide 1512 by 819, we get 1 and a remainder of 693.
Put 1 as the next digit of the answer. 
Result so far: 8501.0
If we subtract 819 from 1512, we get 693.
Take the next digit (6) from the dividend and append it to 693, then repeat: 6936 / 819

Moving on to step 8:
6936 divided by 819 is 8 with a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 85018.0
If we take 6552 away from 6936, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 9:
819 goes into 3840 4 times with a remainder of 564.
The number 4 becomes the next digit in our result. 
Result so far: 85018.4
If we take 3276 away from 3840, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 10:
When dividing 5640 by 819, we get 6 with a remainder of 726.
Put 6 as the next digit of the answer. 
Result so far: 85018.46
Subtract 4914 from 5640 to get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Step 11:
7260 divided by 819 is 8 with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 85018.468
If we take 6552 away from 7260, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 12:
7080 divided by 819 is 8 with a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 85018.4688
If we subtract 6552 from 7080, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final result is 85018.4688 with a remainder of 0.00528.
