721360 ÷ 34 
Our goal is to divide 721360 by 34.

Step 1:
When dividing 7 by 34, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 34

On to step 2:
When dividing 72 by 34, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 68 from 72 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 34

Going ahead to step 3:
34 goes into 41 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 34 from 41 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 34

Moving on to step 4:
When dividing 73 by 34, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
If we subtract 68 from 73, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 34

Advancing to step 5:
When dividing 56 by 34, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 2121.0
The remainder is 22 after subtracting 34 from 56.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 34

On to step 6:
When dividing 220 by 34, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 21216.0
Deduct 204 from 220 and we're left 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.

Step 7:
160 divided by 34 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 21216.4
The remainder is 24 after subtracting 136 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
The number 34 fits into 240 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 21216.47
If we subtract 238 from 240, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
34 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 21216.47
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
34 can be fit into 200 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 21216.4705
If we take 170 away from 200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
34 can be fit into 300 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 21216.47058
Deduct 272 from 300 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
34 can be fit into 280 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 21216.470588
If we subtract 272 from 280, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 21216.470588, with a leftover of 8e-07.
