We're dividing 64657811 by 871 
We want to figure out the number of times 64657811 can be divided by 871.

Advancing to step 1:
871 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 871

On to step 2:
64 divided by 871 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 871

On to step 3:
If we divide 646 by 871, we get 0 and a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 646, we end up with 646.
Append the next digit (5) from the dividend to 646 and continue with: 6465 / 871

On to step 4:
When dividing 6465 by 871, we get 7 with a remainder of 368.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 6097 from 6465 to get 368.
Append the next digit (7) from the dividend to 368 and continue with: 3687 / 871

Step 5:
The number 871 fits into 3687 4 times, leaving a remainder of 203.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtract 3484 from 3687 to get 203.
Append the next digit (8) from the dividend to 203 and continue with: 2038 / 871

On to step 6:
871 goes into 2038 2 times with a remainder of 296.
The next digit of our result is 2. 
Result so far: 742.0
The remainder is 296 after subtracting 1742 from 2038.
Bring next digit (1) of the dividend behind the 296 and repeat the process: 2961 / 871

Moving on to step 7:
If we divide 2961 by 871, we get 3 and a remainder of 348.
The number 3 becomes the next digit in our result. 
Result so far: 7423.0
Subtract 2613 from 2961 to get 348.
Grab the next digit (1) from the dividend, add it to 348, then carry on: 3481 / 871

Advancing to step 8:
871 goes into 3481 3 times with a remainder of 868.
The number 3 becomes the next digit in our result. 
Result so far: 74233.0
If we subtract 2613 from 3481, we get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Going ahead to step 9:
When dividing 8680 by 871, we get 9 with a remainder of 841.
The number 9 becomes the next digit in our result. 
Result so far: 74233.9
If we subtract 7839 from 8680, we get 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Moving on to step 10:
The number 871 fits into 8410 9 times, leaving a remainder of 571.
Write down 9 as next digit of the result. 
Result so far: 74233.99
Deduct 7839 from 8410 and we're left with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

After the division, we end up with 74233.99 and a remainder of 0.571.
