We divide 21121101 by 303
Our goal is to divide 21121101 by 303.

Step 1:
303 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 303

Moving on to step 2:
21 divided by 303 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 303

Let's proceed to step 3:
If we divide 211 by 303, we get 0 and a remainder of 211.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Grab the next digit (2) from the dividend, add it to 211, then carry on: 2112 / 303

Moving on to step 4:
303 can be fit into 2112 6 times, resulting in a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 1818 from 2112, we get 294.
Fetch the next digit (1) from the dividend, attach it to 294 and continue: 2941 / 303

Advancing to step 5:
If we divide 2941 by 303, we get 9 and a remainder of 214.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 2727 from 2941 and we're left with 214.
Fetch the next digit (1) from the dividend, attach it to 214 and continue: 2141 / 303

Let's proceed to step 6:
303 goes into 2141 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 697.0
If we take 2121 away from 2141, we end up with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 303

Step 7:
303 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 6970.0
If we take 0 away from 200, we end up with 200.
Fetch the next digit (1) from the dividend, attach it to 200 and continue: 2001 / 303

Step 8:
The number 303 fits into 2001 6 times, leaving a remainder of 183.
Write down 6 as next digit of the result. 
Result so far: 69706.0
Deduct 1818 from 2001 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
303 goes into 1830 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 69706.6
If we subtract 1818 from 1830, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 303 is 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 69706.6
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
303 goes into 1200 3 times with a remainder of 291.
Record the quotient 3 as the next digit in the result. 
Result so far: 69706.603
Deduct 909 from 1200 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 12:
303 can be fit into 2910 9 times, resulting in a remainder of 183.
Put 9 as the next digit of the answer. 
Result so far: 69706.6039
If we take 2727 away from 2910, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 13:
1830 divided by 303 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 69706.60396
If we subtract 1818 from 1830, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
The number 303 fits into 120 0 times, leaving a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 69706.60396
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
1200 divided by 303 is 3 with a remainder of 291.
Record the quotient 3 as the next digit in the result. 
Result so far: 69706.6039603
The remainder is 291 after subtracting 909 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 16:
303 goes into 2910 9 times with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 69706.60396039
The remainder is 183 after subtracting 2727 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final result is 69706.60396039 with a remainder of 1.83e-07.
