10200120 divided by 66 
Let's see how many times 66 fits into 10200120.

Let's proceed to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 66

Going ahead to step 2:
The number 66 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 66

Moving on to step 3:
102 divided by 66 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 102 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 66

Step 4:
360 divided by 66 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 30 after subtracting 330 from 360.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 66

On to step 5:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 154.0
If we take 264 away from 300, we end up with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 66

Let's proceed to step 6:
If we divide 361 by 66, we get 5 and a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 1545.0
If we take 330 away from 361, we end up with 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 66

On to step 7:
When dividing 312 by 66, we get 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 15454.0
Deduct 264 from 312 and we're left with 48.
Grab the next digit (0) from the dividend, add it to 48, then carry on: 480 / 66

Going ahead to step 8:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 154547.0
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 66 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 154547.2
Subtracting 132 from 180 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 66 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 154547.27
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 66 fits into 180 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 154547.272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
66 goes into 480 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 154547.2727
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
66 goes into 180 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 154547.27272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
The number 66 fits into 480 7 times, leaving a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 154547.272727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
When dividing 180 by 66, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 154547.2727272
Subtract 132 from 180 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
If we divide 480 by 66, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 154547.27272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.
