We're dividing 34085454 by 810 
The aim is to understand the frequency of 810 in 34085454.

Moving on to step 1:
810 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 810

Going ahead to step 2:
34 divided by 810 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 810

Let's proceed to step 3:
If we divide 340 by 810, we get 0 and a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 340, we get 340.
Bring next digit (8) of the dividend behind the 340 and repeat the process: 3408 / 810

Going ahead to step 4:
If we divide 3408 by 810, we get 4 and a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3240 from 3408 and we're left with 168.
Include the next digit (5) from the dividend after 168, then repeat: 1685 / 810

On to step 5:
1685 divided by 810 is 2 with a remainder of 65.
Use 2 as the next digit of our solution. 
Result so far: 42.0
The remainder is 65 after subtracting 1620 from 1685.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 810

On to step 6:
The number 810 fits into 654 0 times, leaving a remainder of 654.
Use 0 as the next digit of our solution. 
Result so far: 420.0
If we subtract 0 from 654, we get 654.
Append the next digit (5) from the dividend to 654 and continue with: 6545 / 810

Advancing to step 7:
The number 810 fits into 6545 8 times, leaving a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 4208.0
If we take 6480 away from 6545, we end up with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 810

Advancing to step 8:
810 goes into 654 0 times with a remainder of 654.
The next digit of our result is 0. 
Result so far: 42080.0
Subtract 0 from 654 to get 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 9:
If we divide 6540 by 810, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 42080.8
If we take 6480 away from 6540, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
When dividing 600 by 810, we get 0 with a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 42080.8
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
If we divide 6000 by 810, we get 7 and a remainder of 330.
Put 7 as the next digit of the answer. 
Result so far: 42080.807
If we subtract 5670 from 6000, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 12:
3300 divided by 810 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 42080.8074
The remainder is 60 after subtracting 3240 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
810 can be fit into 600 0 times, resulting in a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 42080.8074
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 14:
If we divide 6000 by 810, we get 7 and a remainder of 330.
The number 7 becomes the next digit in our result. 
Result so far: 42080.807407
The remainder is 330 after subtracting 5670 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 15:
3300 divided by 810 is 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 42080.8074074
Deduct 3240 from 3300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
810 goes into 600 0 times with a remainder of 600.
The next digit of our result is 0. 
Result so far: 42080.8074074
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 42080.8074074, and the remainder is 6e-07.
