Let's divide 636611 by 81
We're looking to find how many times 81 goes into 636611.

Advancing to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 81

Advancing to step 2:
If we divide 63 by 81, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 81

Advancing to step 3:
If we divide 636 by 81, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 567 from 636, we get 69.
Grab the next digit (6) from the dividend, add it to 69, then carry on: 696 / 81

Moving on to step 4:
696 divided by 81 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 648 from 696 and we're left with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 81

Let's proceed to step 5:
481 divided by 81 is 5 with a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 785.0
Subtracting 405 from 481 leaves us with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 81

Step 6:
The number 81 fits into 761 9 times, leaving a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 7859.0
If we subtract 729 from 761, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
81 can be fit into 320 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 7859.3
Subtracting 243 from 320 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 8:
The number 81 fits into 770 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 7859.39
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 7859.395
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
If we divide 50 by 81, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7859.395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 81, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7859.39506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 81 is 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 7859.395061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 13:
When dividing 590 by 81, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 7859.3950617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
230 divided by 81 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 7859.39506172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 7859.39506172 with a balance of 6.8e-08.
