We divide 3722521 by 578
Our goal is to divide 3722521 by 578.

Going ahead to step 1:
When dividing 3 by 578, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 578

Moving on to step 2:
The number 578 fits into 37 0 times, leaving a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 578

Let's proceed to step 3:
The number 578 fits into 372 0 times, leaving a remainder of 372.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 372, we get 372.
Take the next digit (2) from the dividend and append it to 372, then repeat: 3722 / 578

On to step 4:
3722 divided by 578 is 6 with a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 3468 from 3722 to get 254.
Bring next digit (5) of the dividend behind the 254 and repeat the process: 2545 / 578

On to step 5:
When dividing 2545 by 578, we get 4 with a remainder of 233.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 2312 from 2545 to get 233.
Fetch the next digit (2) from the dividend, attach it to 233 and continue: 2332 / 578

Let's proceed to step 6:
If we divide 2332 by 578, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 644.0
The remainder is 20 after subtracting 2312 from 2332.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 578

On to step 7:
If we divide 201 by 578, we get 0 and a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 6440.0
If we subtract 0 from 201, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 8:
The number 578 fits into 2010 3 times, leaving a remainder of 276.
The next digit of our result is 3. 
Result so far: 6440.3
Subtracting 1734 from 2010 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 9:
If we divide 2760 by 578, we get 4 and a remainder of 448.
The next digit of our result is 4. 
Result so far: 6440.34
Deduct 2312 from 2760 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 10:
578 goes into 4480 7 times with a remainder of 434.
Write down 7 as next digit of the result. 
Result so far: 6440.347
The remainder is 434 after subtracting 4046 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 11:
If we divide 4340 by 578, we get 7 and a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 6440.3477
Subtracting 4046 from 4340 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

In conclusion, the division gives 6440.3477 with a balance of 0.00294.
