We're dividing 12834953 by 805 
The aim is to understand the frequency of 805 in 12834953.

Advancing to step 1:
The number 805 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 805

Advancing to step 2:
12 divided by 805 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 805

On to step 3:
The number 805 fits into 128 0 times, leaving a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Take the next digit (3) from the dividend and append it to 128, then repeat: 1283 / 805

On to step 4:
When dividing 1283 by 805, we get 1 with a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 805 from 1283 to get 478.
Include the next digit (4) from the dividend after 478, then repeat: 4784 / 805

Moving on to step 5:
If we divide 4784 by 805, we get 5 and a remainder of 759.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 759 after subtracting 4025 from 4784.
Append the next digit (9) from the dividend to 759 and continue with: 7599 / 805

Let's proceed to step 6:
The number 805 fits into 7599 9 times, leaving a remainder of 354.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtract 7245 from 7599 to get 354.
Grab the next digit (5) from the dividend, add it to 354, then carry on: 3545 / 805

Moving on to step 7:
The number 805 fits into 3545 4 times, leaving a remainder of 325.
The number 4 becomes the next digit in our result. 
Result so far: 1594.0
Deduct 3220 from 3545 and we're left with 325.
Append the next digit (3) from the dividend to 325 and continue with: 3253 / 805

On to step 8:
When dividing 3253 by 805, we get 4 with a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 15944.0
The remainder is 33 after subtracting 3220 from 3253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
805 goes into 330 0 times with a remainder of 330.
The next digit of our result is 0. 
Result so far: 15944.0
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
If we divide 3300 by 805, we get 4 and a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 15944.04
The remainder is 80 after subtracting 3220 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
800 divided by 805 is 0 with a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 15944.04
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 12:
The number 805 fits into 8000 9 times, leaving a remainder of 755.
Write down 9 as next digit of the result. 
Result so far: 15944.0409
Subtract 7245 from 8000 to get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Going ahead to step 13:
If we divide 7550 by 805, we get 9 and a remainder of 305.
Record the quotient 9 as the next digit in the result. 
Result so far: 15944.04099
Subtract 7245 from 7550 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The final result is 15944.04099 with a remainder of 0.000305.
