85687373 divided by 829 
The aim is to understand the frequency of 829 in 85687373.

Let's proceed to step 1:
829 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 829

Step 2:
85 divided by 829 is 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 829

Let's proceed to step 3:
The number 829 fits into 856 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 829 from 856 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 829

Advancing to step 4:
If we divide 278 by 829, we get 0 and a remainder of 278.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 278, we get 278.
Bring next digit (7) of the dividend behind the 278 and repeat the process: 2787 / 829

Let's proceed to step 5:
The number 829 fits into 2787 3 times, leaving a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 2487 from 2787, we get 300.
Fetch the next digit (3) from the dividend, attach it to 300 and continue: 3003 / 829

Advancing to step 6:
829 can be fit into 3003 3 times, resulting in a remainder of 516.
Record the quotient 3 as the next digit in the result. 
Result so far: 1033.0
If we take 2487 away from 3003, we end up with 516.
Append the next digit (7) from the dividend to 516 and continue with: 5167 / 829

Advancing to step 7:
When dividing 5167 by 829, we get 6 with a remainder of 193.
Use 6 as the next digit of our solution. 
Result so far: 10336.0
Subtracting 4974 from 5167 leaves us with 193.
Include the next digit (3) from the dividend after 193, then repeat: 1933 / 829

Let's proceed to step 8:
829 goes into 1933 2 times with a remainder of 275.
The number 2 becomes the next digit in our result. 
Result so far: 103362.0
Deduct 1658 from 1933 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 9:
829 can be fit into 2750 3 times, resulting in a remainder of 263.
The number 3 becomes the next digit in our result. 
Result so far: 103362.3
Deduct 2487 from 2750 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 10:
829 can be fit into 2630 3 times, resulting in a remainder of 143.
The number 3 becomes the next digit in our result. 
Result so far: 103362.33
If we take 2487 away from 2630, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final outcome is 103362.33, with a leftover of 0.143.
