80149495 ÷ 820 
Our goal is to divide 80149495 by 820.

Advancing to step 1:
8 divided by 820 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 820

Moving on to step 2:
820 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 820

Step 3:
820 can be fit into 801 0 times, resulting in a remainder of 801.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 801 to get 801.
Take the next digit (4) from the dividend and append it to 801, then repeat: 8014 / 820

On to step 4:
If we divide 8014 by 820, we get 9 and a remainder of 634.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7380 away from 8014, we end up with 634.
Fetch the next digit (9) from the dividend, attach it to 634 and continue: 6349 / 820

Moving on to step 5:
When dividing 6349 by 820, we get 7 with a remainder of 609.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 609 after subtracting 5740 from 6349.
Grab the next digit (4) from the dividend, add it to 609, then carry on: 6094 / 820

Going ahead to step 6:
6094 divided by 820 is 7 with a remainder of 354.
Write down 7 as next digit of the result. 
Result so far: 977.0
If we take 5740 away from 6094, we end up with 354.
Grab the next digit (9) from the dividend, add it to 354, then carry on: 3549 / 820

Step 7:
3549 divided by 820 is 4 with a remainder of 269.
Write down 4 as next digit of the result. 
Result so far: 9774.0
Deduct 3280 from 3549 and we're left with 269.
Bring next digit (5) of the dividend behind the 269 and repeat the process: 2695 / 820

Going ahead to step 8:
When dividing 2695 by 820, we get 3 with a remainder of 235.
Use 3 as the next digit of our solution. 
Result so far: 97743.0
Deduct 2460 from 2695 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
When dividing 2350 by 820, we get 2 with a remainder of 710.
Write down 2 as next digit of the result. 
Result so far: 97743.2
Subtract 1640 from 2350 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 10:
When dividing 7100 by 820, we get 8 with a remainder of 540.
Use 8 as the next digit of our solution. 
Result so far: 97743.28
Deduct 6560 from 7100 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 11:
If we divide 5400 by 820, we get 6 and a remainder of 480.
The next digit of our result is 6. 
Result so far: 97743.286
Subtract 4920 from 5400 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 12:
The number 820 fits into 4800 5 times, leaving a remainder of 700.
The next digit of our result is 5. 
Result so far: 97743.2865
If we take 4100 away from 4800, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 13:
7000 divided by 820 is 8 with a remainder of 440.
Record the quotient 8 as the next digit in the result. 
Result so far: 97743.28658
Deduct 6560 from 7000 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 14:
820 goes into 4400 5 times with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 97743.286585
If we subtract 4100 from 4400, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 15:
The number 820 fits into 3000 3 times, leaving a remainder of 540.
Put 3 as the next digit of the answer. 
Result so far: 97743.2865853
If we subtract 2460 from 3000, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 16:
820 goes into 5400 6 times with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 97743.28658536
If we take 4920 away from 5400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 97743.28658536 with a remaining 4.8e-07.
