45051894 divided by 810 
Let's see how many times 810 fits into 45051894.

On to step 1:
When dividing 4 by 810, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 810

Moving on to step 2:
810 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 810

Going ahead to step 3:
810 can be fit into 450 0 times, resulting in a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 450 leaves us with 450.
Take the next digit (5) from the dividend and append it to 450, then repeat: 4505 / 810

Step 4:
810 can be fit into 4505 5 times, resulting in a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 4050 from 4505 and we're left with 455.
Include the next digit (1) from the dividend after 455, then repeat: 4551 / 810

Let's proceed to step 5:
If we divide 4551 by 810, we get 5 and a remainder of 501.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 501 after subtracting 4050 from 4551.
Bring next digit (8) of the dividend behind the 501 and repeat the process: 5018 / 810

Advancing to step 6:
When dividing 5018 by 810, we get 6 with a remainder of 158.
The next digit of our result is 6. 
Result so far: 556.0
The remainder is 158 after subtracting 4860 from 5018.
Include the next digit (9) from the dividend after 158, then repeat: 1589 / 810

Step 7:
If we divide 1589 by 810, we get 1 and a remainder of 779.
Use 1 as the next digit of our solution. 
Result so far: 5561.0
The remainder is 779 after subtracting 810 from 1589.
Append the next digit (4) from the dividend to 779 and continue with: 7794 / 810

Step 8:
810 can be fit into 7794 9 times, resulting in a remainder of 504.
Write down 9 as next digit of the result. 
Result so far: 55619.0
Subtracting 7290 from 7794 leaves us with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 9:
The number 810 fits into 5040 6 times, leaving a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 55619.6
If we subtract 4860 from 5040, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
When dividing 1800 by 810, we get 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 55619.62
If we subtract 1620 from 1800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 810 fits into 1800 2 times, leaving a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 55619.622
If we take 1620 away from 1800, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 55619.622 with a balance of 0.018.
