We're dividing 73751645 by 835 
The aim is to understand the frequency of 835 in 73751645.

Step 1:
835 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 835

Going ahead to step 2:
The number 835 fits into 73 0 times, leaving a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 835

Moving on to step 3:
The number 835 fits into 737 0 times, leaving a remainder of 737.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 737 and we're left with 737.
Include the next digit (5) from the dividend after 737, then repeat: 7375 / 835

Let's proceed to step 4:
If we divide 7375 by 835, we get 8 and a remainder of 695.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6680 from 7375 and we're left with 695.
Grab the next digit (1) from the dividend, add it to 695, then carry on: 6951 / 835

On to step 5:
If we divide 6951 by 835, we get 8 and a remainder of 271.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 6680 from 6951, we get 271.
Take the next digit (6) from the dividend and append it to 271, then repeat: 2716 / 835

Step 6:
2716 divided by 835 is 3 with a remainder of 211.
Use 3 as the next digit of our solution. 
Result so far: 883.0
The remainder is 211 after subtracting 2505 from 2716.
Fetch the next digit (4) from the dividend, attach it to 211 and continue: 2114 / 835

Moving on to step 7:
2114 divided by 835 is 2 with a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 8832.0
Deduct 1670 from 2114 and we're left with 444.
Append the next digit (5) from the dividend to 444 and continue with: 4445 / 835

Moving on to step 8:
If we divide 4445 by 835, we get 5 and a remainder of 270.
Use 5 as the next digit of our solution. 
Result so far: 88325.0
Subtract 4175 from 4445 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
The number 835 fits into 2700 3 times, leaving a remainder of 195.
Record the quotient 3 as the next digit in the result. 
Result so far: 88325.3
The remainder is 195 after subtracting 2505 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 10:
835 goes into 1950 2 times with a remainder of 280.
The next digit of our result is 2. 
Result so far: 88325.32
Subtract 1670 from 1950 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 11:
835 goes into 2800 3 times with a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 88325.323
Deduct 2505 from 2800 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 12:
If we divide 2950 by 835, we get 3 and a remainder of 445.
The number 3 becomes the next digit in our result. 
Result so far: 88325.3233
If we subtract 2505 from 2950, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final result is 88325.3233 with a remainder of 0.00445.
