81204204 ÷ 31 
We want to figure out the number of times 81204204 can be divided by 31.

Step 1:
8 divided by 31 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 31

Advancing to step 2:
31 goes into 81 2 times with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 62 from 81 leaves us with 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 31

Step 3:
When dividing 192 by 31, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 186 away from 192, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 31

On to step 4:
60 divided by 31 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 261.0
If we subtract 31 from 60, we get 29.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 31

Going ahead to step 5:
31 can be fit into 294 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 2619.0
Subtract 279 from 294 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 31

Step 6:
31 goes into 152 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 26194.0
The remainder is 28 after subtracting 124 from 152.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 31

Let's proceed to step 7:
When dividing 280 by 31, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 261949.0
If we take 279 away from 280, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 31

Moving on to step 8:
When dividing 14 by 31, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 2619490.0
If we subtract 0 from 14, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
31 goes into 140 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2619490.4
Subtract 124 from 140 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2619490.45
Subtracting 155 from 160 leaves us 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.

Step 11:
The number 31 fits into 50 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 2619490.451
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
31 goes into 190 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2619490.4516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 2619490.45161
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 2619490.451612
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 15:
When dividing 280 by 31, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 2619490.4516129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 16:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2619490.4516129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2619490.4516129, and the remainder is 1e-08.
