43475577 divided by 810 
We want to figure out the number of times 43475577 can be divided by 810.

On to step 1:
If we divide 4 by 810, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 810

Moving on to step 2:
43 divided by 810 is 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 810

Let's proceed to step 3:
434 divided by 810 is 0 with a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Include the next digit (7) from the dividend after 434, then repeat: 4347 / 810

Step 4:
4347 divided by 810 is 5 with a remainder of 297.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4050 from 4347 and we're left with 297.
Append the next digit (5) from the dividend to 297 and continue with: 2975 / 810

Moving on to step 5:
810 goes into 2975 3 times with a remainder of 545.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 545 after subtracting 2430 from 2975.
Bring next digit (5) of the dividend behind the 545 and repeat the process: 5455 / 810

Moving on to step 6:
5455 divided by 810 is 6 with a remainder of 595.
The next digit of our result is 6. 
Result so far: 536.0
Subtract 4860 from 5455 to get 595.
Grab the next digit (7) from the dividend, add it to 595, then carry on: 5957 / 810

On to step 7:
If we divide 5957 by 810, we get 7 and a remainder of 287.
Record the quotient 7 as the next digit in the result. 
Result so far: 5367.0
The remainder is 287 after subtracting 5670 from 5957.
Include the next digit (7) from the dividend after 287, then repeat: 2877 / 810

Step 8:
When dividing 2877 by 810, we get 3 with a remainder of 447.
The number 3 becomes the next digit in our result. 
Result so far: 53673.0
The remainder is 447 after subtracting 2430 from 2877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 9:
810 goes into 4470 5 times with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 53673.5
If we take 4050 away from 4470, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 10:
The number 810 fits into 4200 5 times, leaving a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 53673.55
Subtract 4050 from 4200 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 53673.55 with a remainder of 0.15.
