725221 ÷ 12 
Our goal is to divide 725221 by 12.

Let's proceed to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 12

Step 2:
12 goes into 72 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 72 away from 72, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Let's proceed to step 3:
12 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Moving on to step 4:
The number 12 fits into 52 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 604.0
Deduct 48 from 52 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 5:
42 divided by 12 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 6043.0
The remainder is 6 after subtracting 36 from 42.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 12

Moving on to step 6:
12 goes into 61 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 60435.0
Deduct 60 from 61 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.

On to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 60435.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 60435.08
Subtracting 96 from 100 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 60435.083
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 60435.0833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 60435.0833, with a leftover of 4e-05.
