We look at the division of 871619 by 66 
Let's see how many times 66 fits into 871619.

On to step 1:
66 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 66

Step 2:
When dividing 87 by 66, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 66 from 87 and we're left with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 66

Step 3:
The number 66 fits into 211 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 198 from 211, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 66

On to step 4:
If we divide 136 by 66, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtracting 132 from 136 leaves us with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 66

Step 5:
When dividing 41 by 66, we get 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 1320.0
If we take 0 away from 41, we end up with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 66

Moving on to step 6:
419 divided by 66 is 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 13206.0
The remainder is 23 after subtracting 396 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
66 can be fit into 230 3 times, resulting in a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 13206.3
Subtract 198 from 230 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
320 divided by 66 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 13206.34
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 13206.348
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 10:
66 goes into 320 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 13206.3484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
560 divided by 66 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 13206.34848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
66 can be fit into 320 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 13206.348484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
If we divide 560 by 66, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 13206.3484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 66, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 13206.34848484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 13206.34848484 and a remainder of 5.6e-08.
