We're dividing 1727897 by 434 
We want to divide 1727897 by 434.

On to step 1:
The number 434 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 434

Moving on to step 2:
17 divided by 434 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 434

Advancing to step 3:
When dividing 172 by 434, we get 0 with a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 172 after subtracting 0 from 172.
Bring next digit (7) of the dividend behind the 172 and repeat the process: 1727 / 434

Step 4:
434 goes into 1727 3 times with a remainder of 425.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1302 from 1727 to get 425.
Take the next digit (8) from the dividend and append it to 425, then repeat: 4258 / 434

Let's proceed to step 5:
When dividing 4258 by 434, we get 9 with a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 3906 from 4258 to get 352.
Include the next digit (9) from the dividend after 352, then repeat: 3529 / 434

Moving on to step 6:
The number 434 fits into 3529 8 times, leaving a remainder of 57.
The next digit of our result is 8. 
Result so far: 398.0
The remainder is 57 after subtracting 3472 from 3529.
Append the next digit (7) from the dividend to 57 and continue with: 577 / 434

Let's proceed to step 7:
434 goes into 577 1 times with a remainder of 143.
The next digit of our result is 1. 
Result so far: 3981.0
If we take 434 away from 577, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 8:
If we divide 1430 by 434, we get 3 and a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 3981.3
If we take 1302 away from 1430, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
434 goes into 1280 2 times with a remainder of 412.
Write down 2 as next digit of the result. 
Result so far: 3981.32
Subtract 868 from 1280 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 10:
The number 434 fits into 4120 9 times, leaving a remainder of 214.
The next digit of our result is 9. 
Result so far: 3981.329
Subtracting 3906 from 4120 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 11:
When dividing 2140 by 434, we get 4 with a remainder of 404.
The next digit of our result is 4. 
Result so far: 3981.3294
Subtract 1736 from 2140 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 12:
If we divide 4040 by 434, we get 9 and a remainder of 134.
The number 9 becomes the next digit in our result. 
Result so far: 3981.32949
If we subtract 3906 from 4040, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 13:
434 goes into 1340 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3981.329493
Subtract 1302 from 1340 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
434 goes into 380 0 times with a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 3981.329493
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 15:
The number 434 fits into 3800 8 times, leaving a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 3981.32949308
Subtract 3472 from 3800 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final outcome is 3981.32949308, with a leftover of 3.28e-07.
