Let's divide 40109982 by 15
We want to divide 40109982 by 15.

On to step 1:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 15

Let's proceed to step 2:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 30 from 40 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 15

Advancing to step 3:
If we divide 101 by 15, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 90 from 101 and we're left with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 15

Let's proceed to step 4:
15 can be fit into 110 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 267.0
If we subtract 105 from 110, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 15

Advancing to step 5:
The number 15 fits into 59 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 2673.0
Deduct 45 from 59 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 15

Going ahead to step 6:
When dividing 149 by 15, we get 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 26739.0
Subtracting 135 from 149 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 15

Moving on to step 7:
The number 15 fits into 148 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 267399.0
If we take 135 away from 148, we end up with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 15

Going ahead to step 8:
15 goes into 132 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2673998.0
If we take 120 away from 132, 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.

Let's proceed to step 9:
15 can be fit into 120 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2673998.8
If we subtract 120 from 120, 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.

On to step 10:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2673998.8
Subtracting 0 from 0 leaves us 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 11:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2673998.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2673998.8, with a leftover of 0.0.
