66322542 ÷ 15 
We want to divide 66322542 by 15.

Advancing to step 1:
6 divided by 15 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 15

On to step 2:
The number 15 fits into 66 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 60 from 66, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 15

Going ahead to step 3:
The number 15 fits into 63 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 60 away from 63, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 15

On to step 4:
If we divide 32 by 15, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 442.0
The remainder is 2 after subtracting 30 from 32.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 15

On to step 5:
The number 15 fits into 22 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 4421.0
Subtracting 15 from 22 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 15

Step 6:
The number 15 fits into 75 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 44215.0
If we take 75 away from 75, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 15

Moving on to step 7:
When dividing 4 by 15, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 442150.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 15

Let's proceed to step 8:
15 goes into 42 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 4421502.0
If we take 30 away from 42, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 15 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4421502.8
If we take 120 away from 120, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4421502.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4421502.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4421502.8 with a remaining 0.0.
