45855841 ÷ 810 
The aim is to understand the frequency of 810 in 45855841.

Moving on to step 1:
When dividing 4 by 810, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 810

Let's proceed to step 2:
The number 810 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 810

Step 3:
When dividing 458 by 810, we get 0 with a remainder of 458.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 458 leaves us with 458.
Append the next digit (5) from the dividend to 458 and continue with: 4585 / 810

Moving on to step 4:
The number 810 fits into 4585 5 times, leaving a remainder of 535.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 4050 away from 4585, we end up with 535.
Include the next digit (5) from the dividend after 535, then repeat: 5355 / 810

Step 5:
If we divide 5355 by 810, we get 6 and a remainder of 495.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
If we subtract 4860 from 5355, we get 495.
Take the next digit (8) from the dividend and append it to 495, then repeat: 4958 / 810

Moving on to step 6:
810 can be fit into 4958 6 times, resulting in a remainder of 98.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
Subtract 4860 from 4958 to get 98.
Fetch the next digit (4) from the dividend, attach it to 98 and continue: 984 / 810

On to step 7:
810 goes into 984 1 times with a remainder of 174.
The next digit of our result is 1. 
Result so far: 5661.0
If we take 810 away from 984, we end up with 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 810

Going ahead to step 8:
810 can be fit into 1741 2 times, resulting in a remainder of 121.
Write down 2 as next digit of the result. 
Result so far: 56612.0
If we subtract 1620 from 1741, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
810 can be fit into 1210 1 times, resulting in a remainder of 400.
The next digit of our result is 1. 
Result so far: 56612.1
Deduct 810 from 1210 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
4000 divided by 810 is 4 with a remainder of 760.
The next digit of our result is 4. 
Result so far: 56612.14
Deduct 3240 from 4000 and we're left with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 11:
If we divide 7600 by 810, we get 9 and a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 56612.149
If we subtract 7290 from 7600, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
The number 810 fits into 3100 3 times, leaving a remainder of 670.
Record the quotient 3 as the next digit in the result. 
Result so far: 56612.1493
Deduct 2430 from 3100 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 13:
810 goes into 6700 8 times with a remainder of 220.
Use 8 as the next digit of our solution. 
Result so far: 56612.14938
If we subtract 6480 from 6700, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
The number 810 fits into 2200 2 times, leaving a remainder of 580.
Write down 2 as next digit of the result. 
Result so far: 56612.149382
Subtracting 1620 from 2200 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 15:
When dividing 5800 by 810, we get 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 56612.1493827
Subtract 5670 from 5800 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
810 goes into 1300 1 times with a remainder of 490.
The number 1 becomes the next digit in our result. 
Result so far: 56612.14938271
If we take 810 away from 1300, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final outcome is 56612.14938271, with a leftover of 4.9e-07.
