We divide 11009599 by 399
We want to divide 11009599 by 399.

Let's proceed to step 1:
When dividing 1 by 399, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 399

Going ahead to step 2:
399 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 399

Moving on to step 3:
If we divide 110 by 399, we get 0 and a remainder of 110.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 110 to get 110.
Bring next digit (0) of the dividend behind the 110 and repeat the process: 1100 / 399

On to step 4:
If we divide 1100 by 399, we get 2 and a remainder of 302.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 798 from 1100 and we're left with 302.
Grab the next digit (9) from the dividend, add it to 302, then carry on: 3029 / 399

Moving on to step 5:
When dividing 3029 by 399, we get 7 with a remainder of 236.
Write down 7 as next digit of the result. 
Result so far: 27.0
The remainder is 236 after subtracting 2793 from 3029.
Grab the next digit (5) from the dividend, add it to 236, then carry on: 2365 / 399

On to step 6:
399 can be fit into 2365 5 times, resulting in a remainder of 370.
Use 5 as the next digit of our solution. 
Result so far: 275.0
If we take 1995 away from 2365, we end up with 370.
Grab the next digit (9) from the dividend, add it to 370, then carry on: 3709 / 399

Let's proceed to step 7:
When dividing 3709 by 399, we get 9 with a remainder of 118.
The number 9 becomes the next digit in our result. 
Result so far: 2759.0
If we subtract 3591 from 3709, we get 118.
Bring next digit (9) of the dividend behind the 118 and repeat the process: 1189 / 399

On to step 8:
1189 divided by 399 is 2 with a remainder of 391.
Use 2 as the next digit of our solution. 
Result so far: 27592.0
Deduct 798 from 1189 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 9:
399 can be fit into 3910 9 times, resulting in a remainder of 319.
Record the quotient 9 as the next digit in the result. 
Result so far: 27592.9
If we take 3591 away from 3910, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 10:
The number 399 fits into 3190 7 times, leaving a remainder of 397.
The number 7 becomes the next digit in our result. 
Result so far: 27592.97
The remainder is 397 after subtracting 2793 from 3190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 11:
The number 399 fits into 3970 9 times, leaving a remainder of 379.
Use 9 as the next digit of our solution. 
Result so far: 27592.979
Subtracting 3591 from 3970 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 12:
The number 399 fits into 3790 9 times, leaving a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 27592.9799
Subtract 3591 from 3790 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

The quotient of the division is 27592.9799, and the remainder is 0.00199.
