Let's divide 72197229 by 810
We want to divide 72197229 by 810.

Moving on to step 1:
7 divided by 810 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 810

Step 2:
72 divided by 810 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 810

Moving on to step 3:
810 can be fit into 721 0 times, resulting in a remainder of 721.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 721 to get 721.
Fetch the next digit (9) from the dividend, attach it to 721 and continue: 7219 / 810

Going ahead to step 4:
810 goes into 7219 8 times with a remainder of 739.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 6480 from 7219 leaves us with 739.
Append the next digit (7) from the dividend to 739 and continue with: 7397 / 810

Step 5:
When dividing 7397 by 810, we get 9 with a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 7290 from 7397, we get 107.
Bring next digit (2) of the dividend behind the 107 and repeat the process: 1072 / 810

Step 6:
810 can be fit into 1072 1 times, resulting in a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 891.0
If we subtract 810 from 1072, we get 262.
Append the next digit (2) from the dividend to 262 and continue with: 2622 / 810

Going ahead to step 7:
810 can be fit into 2622 3 times, resulting in a remainder of 192.
Record the quotient 3 as the next digit in the result. 
Result so far: 8913.0
If we take 2430 away from 2622, we end up with 192.
Take the next digit (9) from the dividend and append it to 192, then repeat: 1929 / 810

Going ahead to step 8:
810 goes into 1929 2 times with a remainder of 309.
Write down 2 as next digit of the result. 
Result so far: 89132.0
The remainder is 309 after subtracting 1620 from 1929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
810 can be fit into 3090 3 times, resulting in a remainder of 660.
The next digit of our result is 3. 
Result so far: 89132.3
Subtract 2430 from 3090 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.

Going ahead to step 10:
The number 810 fits into 6600 8 times, leaving a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 89132.38
Subtract 6480 from 6600 to get 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 11:
1200 divided by 810 is 1 with a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 89132.381
If we subtract 810 from 1200, we 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 12:
810 goes into 3900 4 times with a remainder of 660.
The number 4 becomes the next digit in our result. 
Result so far: 89132.3814
If we subtract 3240 from 3900, we 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 13:
810 can be fit into 6600 8 times, resulting in a remainder of 120.
The next digit of our result is 8. 
Result so far: 89132.38148
Deduct 6480 from 6600 and we're left 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.

On to step 14:
810 goes into 1200 1 times with a remainder of 390.
The next digit of our result is 1. 
Result so far: 89132.381481
Subtracting 810 from 1200 leaves us 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.

Going ahead to step 15:
810 goes into 3900 4 times with a remainder of 660.
Put 4 as the next digit of the answer. 
Result so far: 89132.3814814
The remainder is 660 after subtracting 3240 from 3900.
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 16:
810 can be fit into 6600 8 times, resulting in a remainder of 120.
The next digit of our result is 8. 
Result so far: 89132.38148148
The remainder is 120 after subtracting 6480 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 89132.38148148 with a remainder of 1.2e-07.
