We divide 409037 by 51
Our goal is to divide 409037 by 51.

Step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 51

Step 2:
The number 51 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 51

Let's proceed to step 3:
The number 51 fits into 409 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 408 from 409 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 51

Advancing to step 4:
When dividing 10 by 51, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 80.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 51

Advancing to step 5:
103 divided by 51 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 802.0
The remainder is 1 after subtracting 102 from 103.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 51

Let's proceed to step 6:
17 divided by 51 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 8020.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
51 goes into 170 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8020.3
Subtract 153 from 170 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8020.33
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 8020.33 and a remainder of 0.017.
