We're dividing 873635 by 66 
We want to figure out the number of times 873635 can be divided by 66.

Moving on to step 1:
8 divided by 66 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left 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.
The next digit of our result is 1. 
Result so far: 1.0
If we take 66 away from 87, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 66

Step 3:
If we divide 213 by 66, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 198 from 213 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 66

Going ahead to step 4:
If we divide 156 by 66, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtract 132 from 156 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 66

Let's proceed to step 5:
If we divide 243 by 66, we get 3 and a remainder of 45.
The next digit of our result is 3. 
Result so far: 1323.0
If we take 198 away from 243, we end up with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 66

Let's proceed to step 6:
The number 66 fits into 455 6 times, leaving a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 13236.0
The remainder is 59 after subtracting 396 from 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
If we divide 590 by 66, we get 8 and a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 13236.8
Subtract 528 from 590 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
66 can be fit into 620 9 times, resulting in a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 13236.89
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 13236.893
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
620 divided by 66 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 13236.8939
Subtracting 594 from 620 leaves us 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.

Going ahead to step 11:
If we divide 260 by 66, we get 3 and a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 13236.89393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 12:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 13236.893939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
When dividing 260 by 66, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 13236.8939393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 13236.89393939
Subtracting 594 from 620 leaves us 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.

The final result is 13236.89393939 with a remainder of 2.6e-08.
