Let's divide 53409340 by 809
Let's see how many times 809 fits into 53409340.

Step 1:
5 divided by 809 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 809

Let's proceed to step 2:
53 divided by 809 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 809

Step 3:
809 goes into 534 0 times with a remainder of 534.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 534 and we're left with 534.
Append the next digit (0) from the dividend to 534 and continue with: 5340 / 809

Going ahead to step 4:
The number 809 fits into 5340 6 times, leaving a remainder of 486.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4854 from 5340 and we're left with 486.
Include the next digit (9) from the dividend after 486, then repeat: 4869 / 809

Step 5:
809 can be fit into 4869 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 66.0
Deduct 4854 from 4869 and we're left with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 809

Step 6:
If we divide 153 by 809, we get 0 and a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 660.0
Deduct 0 from 153 and we're left with 153.
Bring next digit (4) of the dividend behind the 153 and repeat the process: 1534 / 809

Moving on to step 7:
If we divide 1534 by 809, we get 1 and a remainder of 725.
Write down 1 as next digit of the result. 
Result so far: 6601.0
If we subtract 809 from 1534, we get 725.
Take the next digit (0) from the dividend and append it to 725, then repeat: 7250 / 809

Moving on to step 8:
7250 divided by 809 is 8 with a remainder of 778.
Record the quotient 8 as the next digit in the result. 
Result so far: 66018.0
Deduct 6472 from 7250 and we're left with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Moving on to step 9:
When dividing 7780 by 809, we get 9 with a remainder of 499.
The next digit of our result is 9. 
Result so far: 66018.9
If we subtract 7281 from 7780, we get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Moving on to step 10:
If we divide 4990 by 809, we get 6 and a remainder of 136.
The next digit of our result is 6. 
Result so far: 66018.96
Subtract 4854 from 4990 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
1360 divided by 809 is 1 with a remainder of 551.
Use 1 as the next digit of our solution. 
Result so far: 66018.961
Deduct 809 from 1360 and we're left with 551.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Advancing to step 12:
The number 809 fits into 5510 6 times, leaving a remainder of 656.
The number 6 becomes the next digit in our result. 
Result so far: 66018.9616
Deduct 4854 from 5510 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 13:
The number 809 fits into 6560 8 times, leaving a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 66018.96168
Deduct 6472 from 6560 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
880 divided by 809 is 1 with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 66018.961681
Subtracting 809 from 880 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 15:
710 divided by 809 is 0 with a remainder of 710.
The number 0 becomes the next digit in our result. 
Result so far: 66018.961681
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 16:
If we divide 7100 by 809, we get 8 and a remainder of 628.
Put 8 as the next digit of the answer. 
Result so far: 66018.96168108
Deduct 6472 from 7100 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

The final outcome is 66018.96168108, with a leftover of 6.28e-07.
