We're dividing 998684 by 66 
Our goal is to divide 998684 by 66.

Step 1:
If we divide 9 by 66, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 66

Step 2:
When dividing 99 by 66, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 66 from 99, we get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 66

Going ahead to step 3:
338 divided by 66 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 330 from 338 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 66

Advancing to step 4:
When dividing 86 by 66, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 66 from 86 and we're left with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 66

Advancing to step 5:
The number 66 fits into 208 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1513.0
Deduct 198 from 208 and we're left with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 66

Moving on to step 6:
If we divide 104 by 66, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 15131.0
The remainder is 38 after subtracting 66 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
66 can be fit into 380 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 15131.5
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 15131.57
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 15131.575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
66 goes into 500 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 15131.5757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 15131.57575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
66 goes into 500 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 15131.575757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 66, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 15131.5757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 15131.57575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 15131.57575757 with a remainder of 3.8e-08.
