Let's divide 84453208 by 828
The aim is to understand the frequency of 828 in 84453208.

On to step 1:
When dividing 8 by 828, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 828

On to step 2:
The number 828 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 828

Advancing to step 3:
If we divide 844 by 828, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 828 from 844, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 828

On to step 4:
828 can be fit into 165 0 times, resulting in a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 165 after subtracting 0 from 165.
Append the next digit (3) from the dividend to 165 and continue with: 1653 / 828

Moving on to step 5:
828 can be fit into 1653 1 times, resulting in a remainder of 825.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 828 from 1653 to get 825.
Append the next digit (2) from the dividend to 825 and continue with: 8252 / 828

Step 6:
828 goes into 8252 9 times with a remainder of 800.
The number 9 becomes the next digit in our result. 
Result so far: 1019.0
If we take 7452 away from 8252, we end up with 800.
Grab the next digit (0) from the dividend, add it to 800, then carry on: 8000 / 828

Going ahead to step 7:
The number 828 fits into 8000 9 times, leaving a remainder of 548.
Record the quotient 9 as the next digit in the result. 
Result so far: 10199.0
Subtract 7452 from 8000 to get 548.
Fetch the next digit (8) from the dividend, attach it to 548 and continue: 5488 / 828

Moving on to step 8:
828 can be fit into 5488 6 times, resulting in a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 101996.0
If we take 4968 away from 5488, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 9:
5200 divided by 828 is 6 with a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 101996.6
Deduct 4968 from 5200 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 10:
828 goes into 2320 2 times with a remainder of 664.
Use 2 as the next digit of our solution. 
Result so far: 101996.62
Deduct 1656 from 2320 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 11:
If we divide 6640 by 828, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 101996.628
If we subtract 6624 from 6640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
When dividing 160 by 828, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 101996.628
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
The number 828 fits into 1600 1 times, leaving a remainder of 772.
Use 1 as the next digit of our solution. 
Result so far: 101996.62801
The remainder is 772 after subtracting 828 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 14:
When dividing 7720 by 828, we get 9 with a remainder of 268.
The next digit of our result is 9. 
Result so far: 101996.628019
Subtracting 7452 from 7720 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 15:
2680 divided by 828 is 3 with a remainder of 196.
Put 3 as the next digit of the answer. 
Result so far: 101996.6280193
Subtracting 2484 from 2680 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 16:
When dividing 1960 by 828, we get 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 101996.62801932
Subtract 1656 from 1960 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final result is 101996.62801932 with a remainder of 3.04e-07.
