65814571 ÷ 828 
The aim is to understand the frequency of 828 in 65814571.

Let's proceed to step 1:
The number 828 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 828

Let's proceed to step 2:
828 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 828

Going ahead to step 3:
When dividing 658 by 828, we get 0 with a remainder of 658.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 658 and we're left with 658.
Fetch the next digit (1) from the dividend, attach it to 658 and continue: 6581 / 828

Moving on to step 4:
6581 divided by 828 is 7 with a remainder of 785.
The next digit of our result is 7. 
Result so far: 7.0
If we take 5796 away from 6581, we end up with 785.
Bring next digit (4) of the dividend behind the 785 and repeat the process: 7854 / 828

Step 5:
The number 828 fits into 7854 9 times, leaving a remainder of 402.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 7452 from 7854, we get 402.
Grab the next digit (5) from the dividend, add it to 402, then carry on: 4025 / 828

Step 6:
4025 divided by 828 is 4 with a remainder of 713.
Use 4 as the next digit of our solution. 
Result so far: 794.0
If we subtract 3312 from 4025, we get 713.
Fetch the next digit (7) from the dividend, attach it to 713 and continue: 7137 / 828

Moving on to step 7:
When dividing 7137 by 828, we get 8 with a remainder of 513.
The number 8 becomes the next digit in our result. 
Result so far: 7948.0
Deduct 6624 from 7137 and we're left with 513.
Bring next digit (1) of the dividend behind the 513 and repeat the process: 5131 / 828

On to step 8:
5131 divided by 828 is 6 with a remainder of 163.
Record the quotient 6 as the next digit in the result. 
Result so far: 79486.0
Subtract 4968 from 5131 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 9:
828 goes into 1630 1 times with a remainder of 802.
Write down 1 as next digit of the result. 
Result so far: 79486.1
If we subtract 828 from 1630, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Step 10:
828 goes into 8020 9 times with a remainder of 568.
The next digit of our result is 9. 
Result so far: 79486.19
If we take 7452 away from 8020, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 11:
The number 828 fits into 5680 6 times, leaving a remainder of 712.
The next digit of our result is 6. 
Result so far: 79486.196
Deduct 4968 from 5680 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 12:
7120 divided by 828 is 8 with a remainder of 496.
Record the quotient 8 as the next digit in the result. 
Result so far: 79486.1968
If we take 6624 away from 7120, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
4960 divided by 828 is 5 with a remainder of 820.
Write down 5 as next digit of the result. 
Result so far: 79486.19685
If we take 4140 away from 4960, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 14:
The number 828 fits into 8200 9 times, leaving a remainder of 748.
Use 9 as the next digit of our solution. 
Result so far: 79486.196859
Subtract 7452 from 8200 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Step 15:
828 can be fit into 7480 9 times, resulting in a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 79486.1968599
If we take 7452 away from 7480, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 79486.1968599, and the remainder is 2.8e-07.
