54474212 divided by 400 
The aim is to understand the frequency of 400 in 54474212.

Going ahead to step 1:
400 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 400

Going ahead to step 2:
If we divide 54 by 400, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 400

Moving on to step 3:
If we divide 544 by 400, we get 1 and a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 400 from 544 and we're left with 144.
Append the next digit (7) from the dividend to 144 and continue with: 1447 / 400

Advancing to step 4:
400 goes into 1447 3 times with a remainder of 247.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1200 from 1447, we get 247.
Fetch the next digit (4) from the dividend, attach it to 247 and continue: 2474 / 400

Step 5:
When dividing 2474 by 400, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtract 2400 from 2474 to get 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 400

Advancing to step 6:
400 can be fit into 742 1 times, resulting in a remainder of 342.
Use 1 as the next digit of our solution. 
Result so far: 1361.0
The remainder is 342 after subtracting 400 from 742.
Include the next digit (1) from the dividend after 342, then repeat: 3421 / 400

Step 7:
When dividing 3421 by 400, we get 8 with a remainder of 221.
Write down 8 as next digit of the result. 
Result so far: 13618.0
Subtract 3200 from 3421 to get 221.
Fetch the next digit (2) from the dividend, attach it to 221 and continue: 2212 / 400

On to step 8:
400 can be fit into 2212 5 times, resulting in a remainder of 212.
Use 5 as the next digit of our solution. 
Result so far: 136185.0
The remainder is 212 after subtracting 2000 from 2212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
When dividing 2120 by 400, we get 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 136185.5
If we subtract 2000 from 2120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
When dividing 1200 by 400, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 136185.53
The remainder is 0 after subtracting 1200 from 1200.
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 11:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136185.53
Subtract 0 from 0 to get 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 12:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 136185.53
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.

The quotient of the division is 136185.53, and the remainder is 0.0.
