We divide 10102210 by 663
Our goal is to divide 10102210 by 663.

Let's proceed to step 1:
The number 663 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 663

Let's proceed to step 2:
663 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 663

On to step 3:
663 goes into 101 0 times with a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 101, we end up with 101.
Bring next digit (0) of the dividend behind the 101 and repeat the process: 1010 / 663

Let's proceed to step 4:
When dividing 1010 by 663, we get 1 with a remainder of 347.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 663 from 1010 to get 347.
Append the next digit (2) from the dividend to 347 and continue with: 3472 / 663

Let's proceed to step 5:
3472 divided by 663 is 5 with a remainder of 157.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 3315 from 3472, we get 157.
Include the next digit (2) from the dividend after 157, then repeat: 1572 / 663

Moving on to step 6:
The number 663 fits into 1572 2 times, leaving a remainder of 246.
Use 2 as the next digit of our solution. 
Result so far: 152.0
The remainder is 246 after subtracting 1326 from 1572.
Fetch the next digit (1) from the dividend, attach it to 246 and continue: 2461 / 663

Moving on to step 7:
The number 663 fits into 2461 3 times, leaving a remainder of 472.
Record the quotient 3 as the next digit in the result. 
Result so far: 1523.0
The remainder is 472 after subtracting 1989 from 2461.
Bring next digit (0) of the dividend behind the 472 and repeat the process: 4720 / 663

Advancing to step 8:
When dividing 4720 by 663, we get 7 with a remainder of 79.
Record the quotient 7 as the next digit in the result. 
Result so far: 15237.0
If we subtract 4641 from 4720, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
790 divided by 663 is 1 with a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 15237.1
The remainder is 127 after subtracting 663 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

On to step 10:
663 can be fit into 1270 1 times, resulting in a remainder of 607.
Put 1 as the next digit of the answer. 
Result so far: 15237.11
Subtract 663 from 1270 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

After the division, we end up with 15237.11 and a remainder of 0.607.
