57663056 ÷ 400 
The aim is to understand the frequency of 400 in 57663056.

Let's proceed to step 1:
The number 400 fits into 5 0 times, leaving 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.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 400

Let's proceed to step 2:
400 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 400

On to step 3:
400 can be fit into 576 1 times, resulting in a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 400 from 576, we get 176.
Fetch the next digit (6) from the dividend, attach it to 176 and continue: 1766 / 400

Step 4:
The number 400 fits into 1766 4 times, leaving a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 166 after subtracting 1600 from 1766.
Include the next digit (3) from the dividend after 166, then repeat: 1663 / 400

Going ahead to step 5:
1663 divided by 400 is 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Subtract 1600 from 1663 to get 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 400

Moving on to step 6:
400 can be fit into 630 1 times, resulting in a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 1441.0
The remainder is 230 after subtracting 400 from 630.
Take the next digit (5) from the dividend and append it to 230, then repeat: 2305 / 400

Let's proceed to step 7:
If we divide 2305 by 400, we get 5 and a remainder of 305.
The next digit of our result is 5. 
Result so far: 14415.0
Subtract 2000 from 2305 to get 305.
Fetch the next digit (6) from the dividend, attach it to 305 and continue: 3056 / 400

Let's proceed to step 8:
If we divide 3056 by 400, we get 7 and a remainder of 256.
Write down 7 as next digit of the result. 
Result so far: 144157.0
If we subtract 2800 from 3056, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 9:
If we divide 2560 by 400, we get 6 and a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 144157.6
If we take 2400 away from 2560, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
When dividing 1600 by 400, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 144157.64
The remainder is 0 after subtracting 1600 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 400 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 144157.64
If we subtract 0 from 0, we 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.

Advancing to step 12:
400 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 144157.64
If we subtract 0 from 0, we 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.

The final outcome is 144157.64, with a leftover of 0.0.
