Let's divide 99636522 by 81
Let's see how many times 81 fits into 99636522.

Step 1:
When dividing 9 by 81, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 81

Going ahead to step 2:
If we divide 99 by 81, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 81 from 99, we get 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 81

Moving on to step 3:
81 can be fit into 186 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 24 after subtracting 162 from 186.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 81

Going ahead to step 4:
81 goes into 243 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we subtract 243 from 243, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 81

Advancing to step 5:
If we divide 6 by 81, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 1230.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 81

Step 6:
If we divide 65 by 81, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 12300.0
If we take 0 away from 65, we end up with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 81

Going ahead to step 7:
81 can be fit into 652 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 123008.0
Subtract 648 from 652 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 81

Let's proceed to step 8:
81 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 1230080.0
Subtract 0 from 42 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
If we divide 420 by 81, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 1230080.5
If we subtract 405 from 420, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
81 goes into 150 1 times with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 1230080.51
If we subtract 81 from 150, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
When dividing 690 by 81, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 1230080.518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1230080.5185
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 1230080.51851
Subtracting 81 from 150 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 14:
When dividing 690 by 81, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 1230080.518518
The remainder is 42 after subtracting 648 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
The number 81 fits into 420 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1230080.5185185
Subtract 405 from 420 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
If we divide 150 by 81, we get 1 and a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 1230080.51851851
Subtract 81 from 150 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 1230080.51851851, and the remainder is 6.9e-08.
