1547016 ÷ 813 
The aim is to understand the frequency of 813 in 1547016.

Moving on to step 1:
When dividing 1 by 813, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 813

On to step 2:
813 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 813

On to step 3:
If we divide 154 by 813, we get 0 and a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 154 and we're left with 154.
Fetch the next digit (7) from the dividend, attach it to 154 and continue: 1547 / 813

Let's proceed to step 4:
1547 divided by 813 is 1 with a remainder of 734.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 734 after subtracting 813 from 1547.
Fetch the next digit (0) from the dividend, attach it to 734 and continue: 7340 / 813

Step 5:
813 goes into 7340 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 7317 from 7340 to get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 813

Going ahead to step 6:
231 divided by 813 is 0 with a remainder of 231.
The next digit of our result is 0. 
Result so far: 190.0
Subtract 0 from 231 to get 231.
Include the next digit (6) from the dividend after 231, then repeat: 2316 / 813

On to step 7:
813 can be fit into 2316 2 times, resulting in a remainder of 690.
Write down 2 as next digit of the result. 
Result so far: 1902.0
If we subtract 1626 from 2316, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Step 8:
813 can be fit into 6900 8 times, resulting in a remainder of 396.
Put 8 as the next digit of the answer. 
Result so far: 1902.8
Subtracting 6504 from 6900 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 9:
813 goes into 3960 4 times with a remainder of 708.
The number 4 becomes the next digit in our result. 
Result so far: 1902.84
Deduct 3252 from 3960 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 10:
When dividing 7080 by 813, we get 8 with a remainder of 576.
Record the quotient 8 as the next digit in the result. 
Result so far: 1902.848
Subtracting 6504 from 7080 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 11:
When dividing 5760 by 813, we get 7 with a remainder of 69.
Use 7 as the next digit of our solution. 
Result so far: 1902.8487
Subtracting 5691 from 5760 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
The number 813 fits into 690 0 times, leaving a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 1902.8487
If we subtract 0 from 690, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 13:
6900 divided by 813 is 8 with a remainder of 396.
Write down 8 as next digit of the result. 
Result so far: 1902.848708
Subtract 6504 from 6900 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 14:
When dividing 3960 by 813, we get 4 with a remainder of 708.
The next digit of our result is 4. 
Result so far: 1902.8487084
Subtract 3252 from 3960 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Moving on to step 15:
813 goes into 7080 8 times with a remainder of 576.
The number 8 becomes the next digit in our result. 
Result so far: 1902.84870848
Deduct 6504 from 7080 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The final outcome is 1902.84870848, with a leftover of 5.76e-07.
