We look at the division of 13338659 by 400 
We want to figure out the number of times 13338659 can be divided by 400.

Step 1:
When dividing 1 by 400, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 400

Step 2:
If we divide 13 by 400, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 400

Advancing to step 3:
400 can be fit into 133 0 times, resulting in a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 133 after subtracting 0 from 133.
Bring next digit (3) of the dividend behind the 133 and repeat the process: 1333 / 400

Let's proceed to step 4:
If we divide 1333 by 400, we get 3 and a remainder of 133.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1200 from 1333, we get 133.
Fetch the next digit (8) from the dividend, attach it to 133 and continue: 1338 / 400

Moving on to step 5:
The number 400 fits into 1338 3 times, leaving a remainder of 138.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 138 after subtracting 1200 from 1338.
Fetch the next digit (6) from the dividend, attach it to 138 and continue: 1386 / 400

Advancing to step 6:
1386 divided by 400 is 3 with a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 333.0
The remainder is 186 after subtracting 1200 from 1386.
Grab the next digit (5) from the dividend, add it to 186, then carry on: 1865 / 400

Advancing to step 7:
The number 400 fits into 1865 4 times, leaving a remainder of 265.
The number 4 becomes the next digit in our result. 
Result so far: 3334.0
If we subtract 1600 from 1865, we get 265.
Append the next digit (9) from the dividend to 265 and continue with: 2659 / 400

Going ahead to step 8:
2659 divided by 400 is 6 with a remainder of 259.
Write down 6 as next digit of the result. 
Result so far: 33346.0
Deduct 2400 from 2659 and we're left with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
When dividing 2590 by 400, we get 6 with a remainder of 190.
Put 6 as the next digit of the answer. 
Result so far: 33346.6
Subtract 2400 from 2590 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
400 can be fit into 1900 4 times, resulting in a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 33346.64
The remainder is 300 after subtracting 1600 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
The next digit of our result is 7. 
Result so far: 33346.647
Subtracting 2800 from 3000 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
If we divide 2000 by 400, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 33346.6475
If we take 2000 away from 2000, we end up 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.

On to step 13:
0 divided by 400 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33346.6475
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33346.6475
Subtracting 0 from 0 leaves us 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.

The final result is 33346.6475 with a remainder of 0.0.
