Let's divide 11991634 by 400
Our goal is to divide 11991634 by 400.

Going ahead to step 1:
If we divide 1 by 400, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
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 / 400

On to step 2:
If we divide 11 by 400, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 400

Going ahead to step 3:
The number 400 fits into 119 0 times, leaving a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 119, we end up with 119.
Grab the next digit (9) from the dividend, add it to 119, then carry on: 1199 / 400

Let's proceed to step 4:
400 can be fit into 1199 2 times, resulting in a remainder of 399.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 800 away from 1199, we end up with 399.
Take the next digit (1) from the dividend and append it to 399, then repeat: 3991 / 400

Going ahead to step 5:
If we divide 3991 by 400, we get 9 and a remainder of 391.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtract 3600 from 3991 to get 391.
Include the next digit (6) from the dividend after 391, then repeat: 3916 / 400

Step 6:
400 goes into 3916 9 times with a remainder of 316.
Write down 9 as next digit of the result. 
Result so far: 299.0
If we subtract 3600 from 3916, we get 316.
Include the next digit (3) from the dividend after 316, then repeat: 3163 / 400

Moving on to step 7:
3163 divided by 400 is 7 with a remainder of 363.
The number 7 becomes the next digit in our result. 
Result so far: 2997.0
Deduct 2800 from 3163 and we're left with 363.
Include the next digit (4) from the dividend after 363, then repeat: 3634 / 400

On to step 8:
3634 divided by 400 is 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 29979.0
Subtract 3600 from 3634 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 400 fits into 340 0 times, leaving a remainder of 340.
The next digit of our result is 0. 
Result so far: 29979.0
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 10:
If we divide 3400 by 400, we get 8 and a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 29979.08
Subtract 3200 from 3400 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
400 can be fit into 2000 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 29979.085
The remainder is 0 after subtracting 2000 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 400, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29979.085
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29979.085
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 29979.085 and a remainder of 0.0.
