We look at the division of 782121 by 73 
We're looking to find how many times 73 goes into 782121.

Moving on to step 1:
73 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 73

Going ahead to step 2:
The number 73 fits into 78 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 5 after subtracting 73 from 78.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 73

Advancing to step 3:
If we divide 52 by 73, we get 0 and a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 52, we get 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 73

Advancing to step 4:
If we divide 521 by 73, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 511 from 521 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 73

Step 5:
If we divide 102 by 73, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
Deduct 73 from 102 and we're left with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 73

Going ahead to step 6:
When dividing 291 by 73, we get 3 with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 10713.0
If we take 219 away from 291, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 7:
73 goes into 720 9 times with a remainder of 63.
Put 9 as the next digit of the answer. 
Result so far: 10713.9
If we take 657 away from 720, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
73 can be fit into 630 8 times, resulting in a remainder of 46.
The next digit of our result is 8. 
Result so far: 10713.98
If we take 584 away from 630, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
If we divide 460 by 73, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 10713.986
The remainder is 22 after subtracting 438 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 73, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 10713.9863
Deduct 219 from 220 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
73 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10713.9863
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
73 can be fit into 100 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 10713.986301
If we take 73 away from 100, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
The number 73 fits into 270 3 times, leaving a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 10713.9863013
Deduct 219 from 270 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
If we divide 510 by 73, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 10713.98630136
If we subtract 438 from 510, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 10713.98630136, and the remainder is 7.2e-08.
