We're dividing 4551269 by 829 
The aim is to understand the frequency of 829 in 4551269.

On to step 1:
When dividing 4 by 829, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 829

Moving on to step 2:
If we divide 45 by 829, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 829

Step 3:
When dividing 455 by 829, we get 0 with a remainder of 455.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 455 to get 455.
Include the next digit (1) from the dividend after 455, then repeat: 4551 / 829

Step 4:
The number 829 fits into 4551 5 times, leaving a remainder of 406.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4145 from 4551 to get 406.
Grab the next digit (2) from the dividend, add it to 406, then carry on: 4062 / 829

On to step 5:
When dividing 4062 by 829, we get 4 with a remainder of 746.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
If we subtract 3316 from 4062, we get 746.
Grab the next digit (6) from the dividend, add it to 746, then carry on: 7466 / 829

Let's proceed to step 6:
The number 829 fits into 7466 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 549.0
Deduct 7461 from 7466 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 829

Moving on to step 7:
The number 829 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 5490.0
Subtract 0 from 59 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
When dividing 590 by 829, we get 0 with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 5490.0
The remainder is 590 after subtracting 0 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 9:
829 goes into 5900 7 times with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 5490.07
Deduct 5803 from 5900 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 10:
829 can be fit into 970 1 times, resulting in a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 5490.071
Deduct 829 from 970 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Advancing to step 11:
If we divide 1410 by 829, we get 1 and a remainder of 581.
Put 1 as the next digit of the answer. 
Result so far: 5490.0711
If we subtract 829 from 1410, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

The final outcome is 5490.0711, with a leftover of 0.00581.
