We look at the division of 11927734 by 400 
The aim is to understand the frequency of 400 in 11927734.

Advancing to step 1:
If we divide 1 by 400, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 400

Step 2:
11 divided by 400 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 400

On to step 3:
If we divide 119 by 400, we get 0 and a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 119 and we're left with 119.
Fetch the next digit (2) from the dividend, attach it to 119 and continue: 1192 / 400

Going ahead to step 4:
1192 divided by 400 is 2 with a remainder of 392.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 800 from 1192 to get 392.
Fetch the next digit (7) from the dividend, attach it to 392 and continue: 3927 / 400

Moving on to step 5:
When dividing 3927 by 400, we get 9 with a remainder of 327.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 3600 from 3927 and we're left with 327.
Take the next digit (7) from the dividend and append it to 327, then repeat: 3277 / 400

On to step 6:
When dividing 3277 by 400, we get 8 with a remainder of 77.
Put 8 as the next digit of the answer. 
Result so far: 298.0
If we subtract 3200 from 3277, we get 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 400

On to step 7:
400 can be fit into 773 1 times, resulting in a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 2981.0
Deduct 400 from 773 and we're left with 373.
Append the next digit (4) from the dividend to 373 and continue with: 3734 / 400

Step 8:
The number 400 fits into 3734 9 times, leaving a remainder of 134.
The next digit of our result is 9. 
Result so far: 29819.0
Subtracting 3600 from 3734 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 9:
When dividing 1340 by 400, we get 3 with a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 29819.3
If we subtract 1200 from 1340, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
400 goes into 1400 3 times with a remainder of 200.
Use 3 as the next digit of our solution. 
Result so far: 29819.33
If we take 1200 away from 1400, we end up 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.

Our division results in 29819.33 with a remaining 0.2.
