We're dividing 431189 by 605 
We want to divide 431189 by 605.

Moving on to step 1:
605 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 605

Moving on to step 2:
If we divide 43 by 605, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 605

Moving on to step 3:
If we divide 431 by 605, we get 0 and a remainder of 431.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 431 to get 431.
Include the next digit (1) from the dividend after 431, then repeat: 4311 / 605

Let's proceed to step 4:
4311 divided by 605 is 7 with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 4235 from 4311 leaves us with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 605

Step 5:
605 can be fit into 768 1 times, resulting in a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 163 after subtracting 605 from 768.
Bring next digit (9) of the dividend behind the 163 and repeat the process: 1639 / 605

Going ahead to step 6:
605 can be fit into 1639 2 times, resulting in a remainder of 429.
The next digit of our result is 2. 
Result so far: 712.0
Subtract 1210 from 1639 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 7:
4290 divided by 605 is 7 with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 712.7
If we take 4235 away from 4290, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
605 can be fit into 550 0 times, resulting in a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 712.7
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 9:
When dividing 5500 by 605, we get 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 712.709
If we take 5445 away from 5500, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 10:
550 divided by 605 is 0 with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 712.709
Subtracting 0 from 550 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
605 can be fit into 5500 9 times, resulting in a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 712.70909
Subtracting 5445 from 5500 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
When dividing 550 by 605, we get 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 712.70909
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 13:
5500 divided by 605 is 9 with a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 712.7090909
If we take 5445 away from 5500, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
When dividing 550 by 605, we get 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 712.7090909
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The final outcome is 712.7090909, with a leftover of 5.5e-07.
