We're dividing 660074 by 40 
Our goal is to divide 660074 by 40.

Going ahead to step 1:
If we divide 6 by 40, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 40

Step 2:
66 divided by 40 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 40 from 66, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 40

On to step 3:
40 goes into 260 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 16.0
If we take 240 away from 260, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 40

Moving on to step 4:
When dividing 200 by 40, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we subtract 200 from 200, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 40

Step 5:
When dividing 7 by 40, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1650.0
If we take 0 away from 7, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 40

Moving on to step 6:
74 divided by 40 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 16501.0
Deduct 40 from 74 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
When dividing 340 by 40, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 16501.8
Subtracting 320 from 340 leaves us 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.

Moving on to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16501.85
Subtract 200 from 200 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.

Step 9:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16501.85
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.

Moving on to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16501.85
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.

Our division results in 16501.85 with a remaining 0.0.
