Let's divide 53492164 by 810
We want to figure out the number of times 53492164 can be divided by 810.

Advancing to step 1:
5 divided by 810 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 810

On to step 2:
The number 810 fits into 53 0 times, leaving a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 810

Step 3:
When dividing 534 by 810, we get 0 with a remainder of 534.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 534, we end up with 534.
Bring next digit (9) of the dividend behind the 534 and repeat the process: 5349 / 810

On to step 4:
810 goes into 5349 6 times with a remainder of 489.
The next digit of our result is 6. 
Result so far: 6.0
If we take 4860 away from 5349, we end up with 489.
Append the next digit (2) from the dividend to 489 and continue with: 4892 / 810

Let's proceed to step 5:
810 goes into 4892 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 66.0
If we take 4860 away from 4892, we end up with 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 810

Advancing to step 6:
When dividing 321 by 810, we get 0 with a remainder of 321.
Write down 0 as next digit of the result. 
Result so far: 660.0
The remainder is 321 after subtracting 0 from 321.
Fetch the next digit (6) from the dividend, attach it to 321 and continue: 3216 / 810

Advancing to step 7:
810 goes into 3216 3 times with a remainder of 786.
Record the quotient 3 as the next digit in the result. 
Result so far: 6603.0
Subtract 2430 from 3216 to get 786.
Bring next digit (4) of the dividend behind the 786 and repeat the process: 7864 / 810

On to step 8:
810 can be fit into 7864 9 times, resulting in a remainder of 574.
Use 9 as the next digit of our solution. 
Result so far: 66039.0
The remainder is 574 after subtracting 7290 from 7864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 9:
810 can be fit into 5740 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 66039.7
Subtract 5670 from 5740 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
The number 810 fits into 700 0 times, leaving a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 66039.7
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
If we divide 7000 by 810, we get 8 and a remainder of 520.
The number 8 becomes the next digit in our result. 
Result so far: 66039.708
Subtracting 6480 from 7000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
810 can be fit into 5200 6 times, resulting in a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 66039.7086
Subtracting 4860 from 5200 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
810 goes into 3400 4 times with a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 66039.70864
The remainder is 160 after subtracting 3240 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
If we divide 1600 by 810, we get 1 and a remainder of 790.
Put 1 as the next digit of the answer. 
Result so far: 66039.708641
If we subtract 810 from 1600, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 15:
810 goes into 7900 9 times with a remainder of 610.
Put 9 as the next digit of the answer. 
Result so far: 66039.7086419
Deduct 7290 from 7900 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 16:
When dividing 6100 by 810, we get 7 with a remainder of 430.
Record the quotient 7 as the next digit in the result. 
Result so far: 66039.70864197
Deduct 5670 from 6100 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

The final outcome is 66039.70864197, with a leftover of 4.3e-07.
