We look at the division of 65400664 by 835 
The aim is to understand the frequency of 835 in 65400664.

Let's proceed to step 1:
6 divided by 835 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 835

Advancing to step 2:
If we divide 65 by 835, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 835

Advancing to step 3:
The number 835 fits into 654 0 times, leaving a remainder of 654.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 654 after subtracting 0 from 654.
Include the next digit (0) from the dividend after 654, then repeat: 6540 / 835

Moving on to step 4:
6540 divided by 835 is 7 with a remainder of 695.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5845 from 6540 and we're left with 695.
Include the next digit (0) from the dividend after 695, then repeat: 6950 / 835

Advancing to step 5:
835 can be fit into 6950 8 times, resulting in a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 6680 from 6950, we get 270.
Append the next digit (6) from the dividend to 270 and continue with: 2706 / 835

Step 6:
The number 835 fits into 2706 3 times, leaving a remainder of 201.
The number 3 becomes the next digit in our result. 
Result so far: 783.0
Subtract 2505 from 2706 to get 201.
Bring next digit (6) of the dividend behind the 201 and repeat the process: 2016 / 835

On to step 7:
835 can be fit into 2016 2 times, resulting in a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 7832.0
If we take 1670 away from 2016, we end up with 346.
Fetch the next digit (4) from the dividend, attach it to 346 and continue: 3464 / 835

On to step 8:
The number 835 fits into 3464 4 times, leaving a remainder of 124.
Put 4 as the next digit of the answer. 
Result so far: 78324.0
The remainder is 124 after subtracting 3340 from 3464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 9:
If we divide 1240 by 835, we get 1 and a remainder of 405.
Record the quotient 1 as the next digit in the result. 
Result so far: 78324.1
If we subtract 835 from 1240, we 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 10:
835 goes into 4050 4 times with a remainder of 710.
Use 4 as the next digit of our solution. 
Result so far: 78324.14
Subtracting 3340 from 4050 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 11:
7100 divided by 835 is 8 with a remainder of 420.
Use 8 as the next digit of our solution. 
Result so far: 78324.148
Subtracting 6680 from 7100 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 12:
835 goes into 4200 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 78324.1485
If we take 4175 away from 4200, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
835 goes into 250 0 times with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 78324.1485
If we take 0 away from 250, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 14:
When dividing 2500 by 835, we get 2 with a remainder of 830.
The number 2 becomes the next digit in our result. 
Result so far: 78324.148502
Subtract 1670 from 2500 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 15:
8300 divided by 835 is 9 with a remainder of 785.
Record the quotient 9 as the next digit in the result. 
Result so far: 78324.1485029
If we subtract 7515 from 8300, we get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Moving on to step 16:
835 can be fit into 7850 9 times, resulting in a remainder of 335.
Use 9 as the next digit of our solution. 
Result so far: 78324.14850299
If we take 7515 away from 7850, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 78324.14850299, and the remainder is 3.35e-07.
