We're dividing 84030031 by 820 
Our goal is to divide 84030031 by 820.

Let's proceed to step 1:
When dividing 8 by 820, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 820

On to step 2:
If we divide 84 by 820, we get 0 and a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 820

On to step 3:
The number 820 fits into 840 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 820 from 840 to get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 820

Let's proceed to step 4:
203 divided by 820 is 0 with a remainder of 203.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 203, we get 203.
Include the next digit (0) from the dividend after 203, then repeat: 2030 / 820

Moving on to step 5:
When dividing 2030 by 820, we get 2 with a remainder of 390.
The next digit of our result is 2. 
Result so far: 102.0
Subtracting 1640 from 2030 leaves us with 390.
Grab the next digit (0) from the dividend, add it to 390, then carry on: 3900 / 820

On to step 6:
If we divide 3900 by 820, we get 4 and a remainder of 620.
Use 4 as the next digit of our solution. 
Result so far: 1024.0
Subtract 3280 from 3900 to get 620.
Grab the next digit (3) from the dividend, add it to 620, then carry on: 6203 / 820

On to step 7:
6203 divided by 820 is 7 with a remainder of 463.
The number 7 becomes the next digit in our result. 
Result so far: 10247.0
If we take 5740 away from 6203, we end up with 463.
Append the next digit (1) from the dividend to 463 and continue with: 4631 / 820

Let's proceed to step 8:
When dividing 4631 by 820, we get 5 with a remainder of 531.
Record the quotient 5 as the next digit in the result. 
Result so far: 102475.0
Subtracting 4100 from 4631 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Advancing to step 9:
5310 divided by 820 is 6 with a remainder of 390.
Use 6 as the next digit of our solution. 
Result so far: 102475.6
If we subtract 4920 from 5310, 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.

Step 10:
820 goes into 3900 4 times with a remainder of 620.
The next digit of our result is 4. 
Result so far: 102475.64
Deduct 3280 from 3900 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 11:
6200 divided by 820 is 7 with a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 102475.647
Subtracting 5740 from 6200 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 12:
820 can be fit into 4600 5 times, resulting in a remainder of 500.
The next digit of our result is 5. 
Result so far: 102475.6475
The remainder is 500 after subtracting 4100 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
If we divide 5000 by 820, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 102475.64756
The remainder is 80 after subtracting 4920 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
The number 820 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 102475.64756
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 15:
If we divide 8000 by 820, we get 9 and a remainder of 620.
The next digit of our result is 9. 
Result so far: 102475.6475609
The remainder is 620 after subtracting 7380 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 16:
820 goes into 6200 7 times with a remainder of 460.
Record the quotient 7 as the next digit in the result. 
Result so far: 102475.64756097
Deduct 5740 from 6200 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

In conclusion, the division gives 102475.64756097 with a balance of 4.6e-07.
