61665049 divided by 828 
The aim is to understand the frequency of 828 in 61665049.

Moving on to step 1:
828 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 828

Moving on to step 2:
828 goes into 61 0 times with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 828

Step 3:
The number 828 fits into 616 0 times, leaving a remainder of 616.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 616 to get 616.
Grab the next digit (6) from the dividend, add it to 616, then carry on: 6166 / 828

Moving on to step 4:
When dividing 6166 by 828, we get 7 with a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 5796 away from 6166, we end up with 370.
Fetch the next digit (5) from the dividend, attach it to 370 and continue: 3705 / 828

Advancing to step 5:
When dividing 3705 by 828, we get 4 with a remainder of 393.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 3312 from 3705, we get 393.
Grab the next digit (0) from the dividend, add it to 393, then carry on: 3930 / 828

Moving on to step 6:
If we divide 3930 by 828, we get 4 and a remainder of 618.
Use 4 as the next digit of our solution. 
Result so far: 744.0
Deduct 3312 from 3930 and we're left with 618.
Append the next digit (4) from the dividend to 618 and continue with: 6184 / 828

Going ahead to step 7:
The number 828 fits into 6184 7 times, leaving a remainder of 388.
Write down 7 as next digit of the result. 
Result so far: 7447.0
If we take 5796 away from 6184, we end up with 388.
Take the next digit (9) from the dividend and append it to 388, then repeat: 3889 / 828

Let's proceed to step 8:
If we divide 3889 by 828, we get 4 and a remainder of 577.
Write down 4 as next digit of the result. 
Result so far: 74474.0
If we take 3312 away from 3889, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Let's proceed to step 9:
If we divide 5770 by 828, we get 6 and a remainder of 802.
The number 6 becomes the next digit in our result. 
Result so far: 74474.6
Deduct 4968 from 5770 and we're left with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Going ahead to step 10:
828 goes into 8020 9 times with a remainder of 568.
The next digit of our result is 9. 
Result so far: 74474.69
Subtracting 7452 from 8020 leaves us 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.

On to step 11:
When dividing 5680 by 828, we get 6 with a remainder of 712.
Write down 6 as next digit of the result. 
Result so far: 74474.696
If we subtract 4968 from 5680, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 12:
When dividing 7120 by 828, we get 8 with a remainder of 496.
The number 8 becomes the next digit in our result. 
Result so far: 74474.6968
The remainder is 496 after subtracting 6624 from 7120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 13:
4960 divided by 828 is 5 with a remainder of 820.
Record the quotient 5 as the next digit in the result. 
Result so far: 74474.69685
The remainder is 820 after subtracting 4140 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 14:
If we divide 8200 by 828, we get 9 and a remainder of 748.
Record the quotient 9 as the next digit in the result. 
Result so far: 74474.696859
If we subtract 7452 from 8200, we 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.

Let's proceed to step 15:
828 goes into 7480 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 74474.6968599
Deduct 7452 from 7480 and we're left 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.

In conclusion, the division gives 74474.6968599 with a balance of 2.8e-07.
