We look at the division of 74561540 by 15 
Let's see how many times 15 fits into 74561540.

Going ahead to step 1:
15 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 15

Moving on to step 2:
15 can be fit into 74 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 14 after subtracting 60 from 74.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 15

Step 3:
When dividing 145 by 15, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 135 away from 145, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 15

Step 4:
If we divide 106 by 15, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 497.0
If we subtract 105 from 106, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 15

Step 5:
15 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 4970.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 15

Let's proceed to step 6:
The number 15 fits into 115 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 49707.0
The remainder is 10 after subtracting 105 from 115.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 15

Going ahead to step 7:
If we divide 104 by 15, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 497076.0
Deduct 90 from 104 and we're left with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 15

Going ahead to step 8:
140 divided by 15 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 4970769.0
If we take 135 away from 140, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 4970769.3
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 4970769.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 4970769.33 with a remaining 0.005.
