Let's divide 42645567 by 810
Let's see how many times 810 fits into 42645567.

Moving on to step 1:
4 divided by 810 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 810

Step 2:
810 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 810

Going ahead to step 3:
If we divide 426 by 810, we get 0 and a remainder of 426.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 426 leaves us with 426.
Take the next digit (4) from the dividend and append it to 426, then repeat: 4264 / 810

Step 4:
810 goes into 4264 5 times with a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4050 from 4264, we get 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 810

Let's proceed to step 5:
810 can be fit into 2145 2 times, resulting in a remainder of 525.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtract 1620 from 2145 to get 525.
Take the next digit (5) from the dividend and append it to 525, then repeat: 5255 / 810

Advancing to step 6:
If we divide 5255 by 810, we get 6 and a remainder of 395.
Record the quotient 6 as the next digit in the result. 
Result so far: 526.0
Subtracting 4860 from 5255 leaves us with 395.
Include the next digit (6) from the dividend after 395, then repeat: 3956 / 810

Let's proceed to step 7:
810 can be fit into 3956 4 times, resulting in a remainder of 716.
Use 4 as the next digit of our solution. 
Result so far: 5264.0
If we subtract 3240 from 3956, we get 716.
Include the next digit (7) from the dividend after 716, then repeat: 7167 / 810

Let's proceed to step 8:
When dividing 7167 by 810, we get 8 with a remainder of 687.
Write down 8 as next digit of the result. 
Result so far: 52648.0
If we take 6480 away from 7167, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Moving on to step 9:
6870 divided by 810 is 8 with a remainder of 390.
Write down 8 as next digit of the result. 
Result so far: 52648.8
If we take 6480 away from 6870, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
810 can be fit into 3900 4 times, resulting in a remainder of 660.
Write down 4 as next digit of the result. 
Result so far: 52648.84
Subtract 3240 from 3900 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Step 11:
If we divide 6600 by 810, we get 8 and a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 52648.848
Subtracting 6480 from 6600 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
810 goes into 1200 1 times with a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 52648.8481
Subtract 810 from 1200 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 13:
3900 divided by 810 is 4 with a remainder of 660.
The number 4 becomes the next digit in our result. 
Result so far: 52648.84814
Subtract 3240 from 3900 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 14:
810 goes into 6600 8 times with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 52648.848148
Subtracting 6480 from 6600 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
If we divide 1200 by 810, we get 1 and a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 52648.8481481
If we take 810 away from 1200, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 16:
810 can be fit into 3900 4 times, resulting in a remainder of 660.
The next digit of our result is 4. 
Result so far: 52648.84814814
If we take 3240 away from 3900, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The quotient of the division is 52648.84814814, and the remainder is 6.6e-07.
