We look at the division of 3556202 by 721 
We're looking to find how many times 721 goes into 3556202.

Let's proceed to step 1:
721 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 721

Going ahead to step 2:
35 divided by 721 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 721

Moving on to step 3:
When dividing 355 by 721, we get 0 with a remainder of 355.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 355 leaves us with 355.
Take the next digit (6) from the dividend and append it to 355, then repeat: 3556 / 721

On to step 4:
If we divide 3556 by 721, we get 4 and a remainder of 672.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2884 from 3556 to get 672.
Fetch the next digit (2) from the dividend, attach it to 672 and continue: 6722 / 721

On to step 5:
721 can be fit into 6722 9 times, resulting in a remainder of 233.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 6489 from 6722 and we're left with 233.
Bring next digit (0) of the dividend behind the 233 and repeat the process: 2330 / 721

Let's proceed to step 6:
721 goes into 2330 3 times with a remainder of 167.
The next digit of our result is 3. 
Result so far: 493.0
Deduct 2163 from 2330 and we're left with 167.
Append the next digit (2) from the dividend to 167 and continue with: 1672 / 721

Moving on to step 7:
721 goes into 1672 2 times with a remainder of 230.
The next digit of our result is 2. 
Result so far: 4932.0
Subtracting 1442 from 1672 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 8:
If we divide 2300 by 721, we get 3 and a remainder of 137.
The next digit of our result is 3. 
Result so far: 4932.3
Deduct 2163 from 2300 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 9:
When dividing 1370 by 721, we get 1 with a remainder of 649.
Write down 1 as next digit of the result. 
Result so far: 4932.31
Deduct 721 from 1370 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Advancing to step 10:
The number 721 fits into 6490 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4932.319
If we take 6489 away from 6490, 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.

Step 11:
If we divide 10 by 721, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4932.319
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.

Advancing to step 12:
721 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 4932.319
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 4932.319, and the remainder is 0.0001.
