81820620 divided by 204 
Our goal is to divide 81820620 by 204.

On to step 1:
The number 204 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 204

On to step 2:
When dividing 81 by 204, we get 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 204

Moving on to step 3:
The number 204 fits into 818 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 816 from 818, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 204

Advancing to step 4:
22 divided by 204 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we take 0 away from 22, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 204

Moving on to step 5:
When dividing 220 by 204, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 401.0
The remainder is 16 after subtracting 204 from 220.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 204

Going ahead to step 6:
The number 204 fits into 166 0 times, leaving a remainder of 166.
The number 0 becomes the next digit in our result. 
Result so far: 4010.0
Subtract 0 from 166 to get 166.
Grab the next digit (2) from the dividend, add it to 166, then carry on: 1662 / 204

Going ahead to step 7:
204 can be fit into 1662 8 times, resulting in a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 40108.0
If we take 1632 away from 1662, we end up with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 204

On to step 8:
204 can be fit into 300 1 times, resulting in a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 401081.0
If we take 204 away from 300, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 9:
When dividing 960 by 204, we get 4 with a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 401081.4
Deduct 816 from 960 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 10:
The number 204 fits into 1440 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 401081.47
The remainder is 12 after subtracting 1428 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
204 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 401081.47
Deduct 0 from 120 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.

Step 12:
The number 204 fits into 1200 5 times, leaving a remainder of 180.
The next digit of our result is 5. 
Result so far: 401081.4705
Deduct 1020 from 1200 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
When dividing 1800 by 204, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 401081.47058
Deduct 1632 from 1800 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 14:
204 goes into 1680 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 401081.470588
If we subtract 1632 from 1680, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 401081.470588 with a remaining 4.8e-06.
