3722963 ÷ 515 
Let's see how many times 515 fits into 3722963.

Let's proceed to step 1:
If we divide 3 by 515, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 515

Moving on to step 2:
The number 515 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
Subtracting 0 from 37 leaves us with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 515

Let's proceed to step 3:
The number 515 fits into 372 0 times, leaving a remainder of 372.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 372 to get 372.
Fetch the next digit (2) from the dividend, attach it to 372 and continue: 3722 / 515

Let's proceed to step 4:
If we divide 3722 by 515, we get 7 and a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 3605 from 3722, we get 117.
Take the next digit (9) from the dividend and append it to 117, then repeat: 1179 / 515

Going ahead to step 5:
515 can be fit into 1179 2 times, resulting in a remainder of 149.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 1030 from 1179, we get 149.
Append the next digit (6) from the dividend to 149 and continue with: 1496 / 515

Advancing to step 6:
1496 divided by 515 is 2 with a remainder of 466.
Put 2 as the next digit of the answer. 
Result so far: 722.0
Subtract 1030 from 1496 to get 466.
Grab the next digit (3) from the dividend, add it to 466, then carry on: 4663 / 515

Advancing to step 7:
515 goes into 4663 9 times with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 7229.0
If we subtract 4635 from 4663, we get 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 8:
515 can be fit into 280 0 times, resulting in a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 7229.0
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
When dividing 2800 by 515, we get 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 7229.05
Subtract 2575 from 2800 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 10:
The number 515 fits into 2250 4 times, leaving a remainder of 190.
The number 4 becomes the next digit in our result. 
Result so far: 7229.054
The remainder is 190 after subtracting 2060 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 11:
515 can be fit into 1900 3 times, resulting in a remainder of 355.
Use 3 as the next digit of our solution. 
Result so far: 7229.0543
If we subtract 1545 from 1900, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 12:
3550 divided by 515 is 6 with a remainder of 460.
The number 6 becomes the next digit in our result. 
Result so far: 7229.05436
If we subtract 3090 from 3550, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
The number 515 fits into 4600 8 times, leaving a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 7229.054368
If we take 4120 away from 4600, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
515 can be fit into 4800 9 times, resulting in a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 7229.0543689
Deduct 4635 from 4800 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 15:
If we divide 1650 by 515, we get 3 and a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 7229.05436893
Deduct 1545 from 1650 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

In conclusion, the division gives 7229.05436893 with a balance of 1.05e-07.
