We divide 12368778 by 400
The aim is to understand the frequency of 400 in 12368778.

Moving on to step 1:
400 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 400

Going ahead to step 2:
400 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 400

Moving on to step 3:
400 can be fit into 123 0 times, resulting in a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Append the next digit (6) from the dividend to 123 and continue with: 1236 / 400

Advancing to step 4:
1236 divided by 400 is 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1200 from 1236, we get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 400

Step 5:
The number 400 fits into 368 0 times, leaving a remainder of 368.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 368 and we're left with 368.
Fetch the next digit (7) from the dividend, attach it to 368 and continue: 3687 / 400

Moving on to step 6:
400 can be fit into 3687 9 times, resulting in a remainder of 87.
Write down 9 as next digit of the result. 
Result so far: 309.0
The remainder is 87 after subtracting 3600 from 3687.
Grab the next digit (7) from the dividend, add it to 87, then carry on: 877 / 400

On to step 7:
The number 400 fits into 877 2 times, leaving a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 3092.0
Subtract 800 from 877 to get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 400

Advancing to step 8:
The number 400 fits into 778 1 times, leaving a remainder of 378.
Use 1 as the next digit of our solution. 
Result so far: 30921.0
Subtract 400 from 778 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 9:
The number 400 fits into 3780 9 times, leaving a remainder of 180.
Put 9 as the next digit of the answer. 
Result so far: 30921.9
If we take 3600 away from 3780, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
400 goes into 1800 4 times with a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 30921.94
Subtract 1600 from 1800 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.

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: 30921.945
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.

Let's proceed to step 12:
400 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30921.945
If we take 0 away from 0, 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.

Going ahead to step 13:
If we divide 0 by 400, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30921.945
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 outcome is 30921.945, with a leftover of 0.0.
