We divide 643286 by 71
We want to divide 643286 by 71.

Let's proceed to step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 71

Going ahead to step 2:
When dividing 64 by 71, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 71

On to step 3:
If we divide 643 by 71, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 639 from 643 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 71

Step 4:
The number 71 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 71

Step 5:
If we divide 428 by 71, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 906.0
If we take 426 away from 428, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 71

Step 6:
If we divide 26 by 71, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 9060.0
If we take 0 away from 26, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
When dividing 260 by 71, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 9060.3
Deduct 213 from 260 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
When dividing 470 by 71, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 9060.36
The remainder is 44 after subtracting 426 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 71, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 9060.366
Deduct 426 from 440 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 9060.366, with a leftover of 0.0014.
