198987 divided by 66 
Our goal is to divide 198987 by 66.

Advancing to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 66

Step 2:
If we divide 19 by 66, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 66

Going ahead to step 3:
198 divided by 66 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 198 from 198, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 66

Moving on to step 4:
If we divide 9 by 66, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 66

Going ahead to step 5:
66 can be fit into 98 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 301.0
The remainder is 32 after subtracting 66 from 98.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 66

Going ahead to step 6:
If we divide 327 by 66, we get 4 and a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 3014.0
Subtracting 264 from 327 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
66 can be fit into 630 9 times, resulting in a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 3014.9
Deduct 594 from 630 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
360 divided by 66 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3014.95
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 66 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3014.954
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
66 goes into 360 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 3014.9545
If we subtract 330 from 360, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
66 can be fit into 300 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3014.95454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3014.954545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
When dividing 300 by 66, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 3014.9545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 66, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3014.95454545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3014.95454545, with a leftover of 3e-08.
