450646 ÷ 71 
Our goal is to divide 450646 by 71.

Advancing to step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 71

Going ahead to step 2:
45 divided by 71 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 71

Let's proceed to step 3:
When dividing 450 by 71, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 426 from 450 to get 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 71

Going ahead to step 4:
The number 71 fits into 246 3 times, leaving a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 213 from 246 leaves us with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 71

Step 5:
71 goes into 334 4 times with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 634.0
Deduct 284 from 334 and we're left with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 71

Moving on to step 6:
71 goes into 506 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 6347.0
If we subtract 497 from 506, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
71 can be fit into 90 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 6347.1
Deduct 71 from 90 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
71 goes into 190 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 6347.12
If we take 142 away from 190, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 71, we get 6 and a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 6347.126
Subtracting 426 from 480 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
When dividing 540 by 71, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 6347.1267
Deduct 497 from 540 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 11:
430 divided by 71 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6347.12676
If we take 426 away from 430, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
If we divide 40 by 71, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6347.12676
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 71 fits into 400 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 6347.1267605
Subtract 355 from 400 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
When dividing 450 by 71, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 6347.12676056
If we subtract 426 from 450, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 6347.12676056, with a leftover of 2.4e-08.
