If we divide 720 by 428, we get 1 and a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 428 away from 720, we end up with 292.
Include the next digit (0) from the dividend after 292, then repeat: 2920 / 428

Going ahead to step 4:
When dividing 2920 by 428, we get 6 with a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2568 from 2920 and we're left with 352.
Fetch the next digit (6) from the dividend, attach it to 352 and continue: 3526 / 428

Moving on to step 5:
The number 428 fits into 3526 8 times, leaving a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we take 3424 away from 3526, we end up with 102.
Include the next digit (7) from the dividend after 102, then repeat: 1027 / 428

Going ahead to step 6:
When dividing 1027 by 428, we get 2 with a remainder of 171.
Use 2 as the next digit of our solution. 
Result so far: 1682.0
Subtract 856 from 1027 to get 171.
Include the next digit (2) from the dividend after 171, then repeat: 1712 / 428

On to step 7:
The number 428 fits into 1712 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 16824.0
Subtract 1712 from 1712 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 428

On to step 8:
428 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 168240.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 428, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 168240.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 428 is 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 168240.02
Deduct 856 from 900 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
440 divided by 428 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 168240.021
The remainder is 12 after subtracting 428 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
428 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 168240.021
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 13:
428 can be fit into 1200 2 times, resulting in a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 168240.02102
Subtracting 856 from 1200 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 14:
3440 divided by 428 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 168240.021028
Subtracting 3424 from 3440 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
428 can be fit into 160 0 times, resulting in a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 168240.021028
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 16:
428 goes into 1600 3 times with a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 168240.02102803
If we take 1284 away from 1600, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

In conclusion, the division gives 168240.02102803 with a balance of 3.16e-07.
