40991968 divided by 820 
Let's see how many times 820 fits into 40991968.

Going ahead to step 1:
4 divided by 820 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 820

Going ahead to step 2:
When dividing 40 by 820, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 820

Advancing to step 3:
When dividing 409 by 820, we get 0 with a remainder of 409.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 409, we end up with 409.
Append the next digit (9) from the dividend to 409 and continue with: 4099 / 820

Let's proceed to step 4:
If we divide 4099 by 820, we get 4 and a remainder of 819.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3280 from 4099, we get 819.
Append the next digit (1) from the dividend to 819 and continue with: 8191 / 820

Let's proceed to step 5:
820 can be fit into 8191 9 times, resulting in a remainder of 811.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 7380 from 8191 leaves us with 811.
Bring next digit (9) of the dividend behind the 811 and repeat the process: 8119 / 820

Advancing to step 6:
When dividing 8119 by 820, we get 9 with a remainder of 739.
Record the quotient 9 as the next digit in the result. 
Result so far: 499.0
If we take 7380 away from 8119, we end up with 739.
Grab the next digit (6) from the dividend, add it to 739, then carry on: 7396 / 820

Moving on to step 7:
The number 820 fits into 7396 9 times, leaving a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 4999.0
If we take 7380 away from 7396, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 820

Step 8:
168 divided by 820 is 0 with a remainder of 168.
The number 0 becomes the next digit in our result. 
Result so far: 49990.0
Deduct 0 from 168 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.

Let's proceed to step 9:
If we divide 1680 by 820, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 49990.2
Subtracting 1640 from 1680 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
820 can be fit into 400 0 times, resulting in a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 49990.2
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
When dividing 4000 by 820, we get 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 49990.204
Deduct 3280 from 4000 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 12:
7200 divided by 820 is 8 with a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 49990.2048
If we take 6560 away from 7200, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 13:
When dividing 6400 by 820, we get 7 with a remainder of 660.
Use 7 as the next digit of our solution. 
Result so far: 49990.20487
The remainder is 660 after subtracting 5740 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 14:
6600 divided by 820 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 49990.204878
If we take 6560 away from 6600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
The number 820 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 49990.204878
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
The number 820 fits into 4000 4 times, leaving a remainder of 720.
Put 4 as the next digit of the answer. 
Result so far: 49990.20487804
If we take 3280 away from 4000, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

The final result is 49990.20487804 with a remainder of 7.2e-07.
