We look at the division of 15069707 by 40 
We want to divide 15069707 by 40.

Going ahead to step 1:
When dividing 1 by 40, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 40

Advancing to step 2:
40 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 40

Advancing to step 3:
When dividing 150 by 40, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 30 after subtracting 120 from 150.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 40

Step 4:
The number 40 fits into 306 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 280 from 306, we get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 40

On to step 5:
40 goes into 269 6 times with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 376.0
The remainder is 29 after subtracting 240 from 269.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 40

Step 6:
40 can be fit into 297 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3767.0
If we subtract 280 from 297, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 40

On to step 7:
If we divide 170 by 40, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 37674.0
Subtract 160 from 170 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 40

Step 8:
The number 40 fits into 107 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 376742.0
If we subtract 80 from 107, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 40 fits into 270 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 376742.6
Deduct 240 from 270 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 40 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 376742.67
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 376742.675
Deduct 200 from 200 and we're left 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.

Advancing to step 12:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 376742.675
If we take 0 away from 0, 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.

Advancing to step 13:
When dividing 0 by 40, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 376742.675
Deduct 0 from 0 and we're left 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.

The final outcome is 376742.675, with a leftover of 0.0.
