We divide 53317093 by 810
We want to figure out the number of times 53317093 can be divided by 810.

On to step 1:
When dividing 5 by 810, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 810

On to step 2:
The number 810 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 810

Advancing to step 3:
533 divided by 810 is 0 with a remainder of 533.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 533, we end up with 533.
Bring next digit (1) of the dividend behind the 533 and repeat the process: 5331 / 810

On to step 4:
810 goes into 5331 6 times with a remainder of 471.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4860 from 5331 and we're left with 471.
Grab the next digit (7) from the dividend, add it to 471, then carry on: 4717 / 810

On to step 5:
810 can be fit into 4717 5 times, resulting in a remainder of 667.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtract 4050 from 4717 to get 667.
Append the next digit (0) from the dividend to 667 and continue with: 6670 / 810

Moving on to step 6:
The number 810 fits into 6670 8 times, leaving a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 658.0
Deduct 6480 from 6670 and we're left with 190.
Bring next digit (9) of the dividend behind the 190 and repeat the process: 1909 / 810

Going ahead to step 7:
When dividing 1909 by 810, we get 2 with a remainder of 289.
The number 2 becomes the next digit in our result. 
Result so far: 6582.0
Subtracting 1620 from 1909 leaves us with 289.
Fetch the next digit (3) from the dividend, attach it to 289 and continue: 2893 / 810

Step 8:
If we divide 2893 by 810, we get 3 and a remainder of 463.
The next digit of our result is 3. 
Result so far: 65823.0
If we subtract 2430 from 2893, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 9:
810 can be fit into 4630 5 times, resulting in a remainder of 580.
Write down 5 as next digit of the result. 
Result so far: 65823.5
The remainder is 580 after subtracting 4050 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 10:
810 can be fit into 5800 7 times, resulting in a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 65823.57
If we subtract 5670 from 5800, we 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 11:
810 can be fit into 1300 1 times, resulting in a remainder of 490.
The number 1 becomes the next digit in our result. 
Result so far: 65823.571
The remainder is 490 after subtracting 810 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
4900 divided by 810 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 65823.5716
Deduct 4860 from 4900 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
810 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 65823.5716
Subtracting 0 from 400 leaves us 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.

Step 14:
The number 810 fits into 4000 4 times, leaving a remainder of 760.
The number 4 becomes the next digit in our result. 
Result so far: 65823.571604
If we take 3240 away from 4000, we end up 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.

Advancing to step 15:
810 can be fit into 7600 9 times, resulting in a remainder of 310.
Use 9 as the next digit of our solution. 
Result so far: 65823.5716049
If we take 7290 away from 7600, we end up with 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 16:
810 can be fit into 3100 3 times, resulting in a remainder of 670.
The next digit of our result is 3. 
Result so far: 65823.57160493
If we subtract 2430 from 3100, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

After the division, we end up with 65823.57160493 and a remainder of 6.7e-07.
