11270889 divided by 400 
The aim is to understand the frequency of 400 in 11270889.

Going ahead to step 1:
The number 400 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 400

Moving on to step 2:
When dividing 11 by 400, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 400

On to step 3:
If we divide 112 by 400, we get 0 and a remainder of 112.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 112 after subtracting 0 from 112.
Fetch the next digit (7) from the dividend, attach it to 112 and continue: 1127 / 400

Step 4:
The number 400 fits into 1127 2 times, leaving a remainder of 327.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 800 from 1127 leaves us with 327.
Bring next digit (0) of the dividend behind the 327 and repeat the process: 3270 / 400

Let's proceed to step 5:
400 can be fit into 3270 8 times, resulting in a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 3200 away from 3270, we end up with 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 400

Going ahead to step 6:
400 goes into 708 1 times with a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 281.0
Deduct 400 from 708 and we're left with 308.
Grab the next digit (8) from the dividend, add it to 308, then carry on: 3088 / 400

Going ahead to step 7:
When dividing 3088 by 400, we get 7 with a remainder of 288.
Record the quotient 7 as the next digit in the result. 
Result so far: 2817.0
Subtracting 2800 from 3088 leaves us with 288.
Append the next digit (9) from the dividend to 288 and continue with: 2889 / 400

Moving on to step 8:
When dividing 2889 by 400, we get 7 with a remainder of 89.
Record the quotient 7 as the next digit in the result. 
Result so far: 28177.0
Subtracting 2800 from 2889 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
890 divided by 400 is 2 with a remainder of 90.
The number 2 becomes the next digit in our result. 
Result so far: 28177.2
Subtracting 800 from 890 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
If we divide 900 by 400, we get 2 and a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 28177.22
If we subtract 800 from 900, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 28177.22 with a remainder of 0.1.
