73109300 divided by 820 
We want to figure out the number of times 73109300 can be divided by 820.

Let's proceed to step 1:
The number 820 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 820

Going ahead to step 2:
820 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 820

On to step 3:
731 divided by 820 is 0 with a remainder of 731.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 731 after subtracting 0 from 731.
Include the next digit (0) from the dividend after 731, then repeat: 7310 / 820

Step 4:
The number 820 fits into 7310 8 times, leaving a remainder of 750.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6560 from 7310 to get 750.
Include the next digit (9) from the dividend after 750, then repeat: 7509 / 820

Step 5:
820 can be fit into 7509 9 times, resulting in a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtract 7380 from 7509 to get 129.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 820

Step 6:
When dividing 1293 by 820, we get 1 with a remainder of 473.
Write down 1 as next digit of the result. 
Result so far: 891.0
Subtract 820 from 1293 to get 473.
Bring next digit (0) of the dividend behind the 473 and repeat the process: 4730 / 820

Let's proceed to step 7:
820 goes into 4730 5 times with a remainder of 630.
The number 5 becomes the next digit in our result. 
Result so far: 8915.0
Subtracting 4100 from 4730 leaves us with 630.
Fetch the next digit (0) from the dividend, attach it to 630 and continue: 6300 / 820

Advancing to step 8:
820 can be fit into 6300 7 times, resulting in a remainder of 560.
Write down 7 as next digit of the result. 
Result so far: 89157.0
The remainder is 560 after subtracting 5740 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 9:
820 goes into 5600 6 times with a remainder of 680.
Put 6 as the next digit of the answer. 
Result so far: 89157.6
If we subtract 4920 from 5600, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 10:
If we divide 6800 by 820, we get 8 and a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 89157.68
If we subtract 6560 from 6800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
2400 divided by 820 is 2 with a remainder of 760.
Use 2 as the next digit of our solution. 
Result so far: 89157.682
If we take 1640 away from 2400, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 12:
The number 820 fits into 7600 9 times, leaving a remainder of 220.
Record the quotient 9 as the next digit in the result. 
Result so far: 89157.6829
The remainder is 220 after subtracting 7380 from 7600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 13:
2200 divided by 820 is 2 with a remainder of 560.
Write down 2 as next digit of the result. 
Result so far: 89157.68292
The remainder is 560 after subtracting 1640 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 14:
When dividing 5600 by 820, we get 6 with a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 89157.682926
Subtracting 4920 from 5600 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 15:
820 can be fit into 6800 8 times, resulting in a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 89157.6829268
If we take 6560 away from 6800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
The number 820 fits into 2400 2 times, leaving a remainder of 760.
The number 2 becomes the next digit in our result. 
Result so far: 89157.68292682
If we take 1640 away from 2400, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The quotient of the division is 89157.68292682, and the remainder is 7.6e-07.
