If we subtract 0 from 68, we get 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 73

Advancing to step 5:
73 goes into 687 9 times with a remainder of 30.
The next digit of our result is 9. 
Result so far: 709.0
Subtracting 657 from 687 leaves us with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 73

Advancing to step 6:
The number 73 fits into 307 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 7094.0
Deduct 292 from 307 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 73

Advancing to step 7:
If we divide 155 by 73, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 70942.0
Deduct 146 from 155 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 73

Advancing to step 8:
73 can be fit into 95 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 709421.0
If we take 73 away from 95, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
The number 73 fits into 220 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 709421.3
If we take 219 away from 220, we end up 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 10:
73 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 709421.3
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 709421.301
If we subtract 73 from 100, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
The number 73 fits into 270 3 times, leaving a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 709421.3013
Subtracting 219 from 270 leaves us 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.

Let's proceed to step 13:
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: 709421.30136
Subtracting 438 from 510 leaves us 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.

Let's proceed to step 14:
720 divided by 73 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 709421.301369
If we subtract 657 from 720, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 15:
If we divide 630 by 73, we get 8 and a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 709421.3013698
Deduct 584 from 630 and we're left 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.

Going ahead to step 16:
If we divide 460 by 73, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 709421.30136986
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.

The quotient of the division is 709421.30136986, and the remainder is 2.2e-08.
