56942818 ÷ 400 
The aim is to understand the frequency of 400 in 56942818.

Step 1:
400 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 400

On to step 2:
The number 400 fits into 56 0 times, leaving a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 400

On to step 3:
569 divided by 400 is 1 with a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 400 from 569, we get 169.
Include the next digit (4) from the dividend after 169, then repeat: 1694 / 400

Advancing to step 4:
The number 400 fits into 1694 4 times, leaving a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 94 after subtracting 1600 from 1694.
Include the next digit (2) from the dividend after 94, then repeat: 942 / 400

Step 5:
942 divided by 400 is 2 with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 142.0
Subtract 800 from 942 to get 142.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 400

Let's proceed to step 6:
400 goes into 1428 3 times with a remainder of 228.
The number 3 becomes the next digit in our result. 
Result so far: 1423.0
The remainder is 228 after subtracting 1200 from 1428.
Include the next digit (1) from the dividend after 228, then repeat: 2281 / 400

Advancing to step 7:
400 goes into 2281 5 times with a remainder of 281.
The next digit of our result is 5. 
Result so far: 14235.0
The remainder is 281 after subtracting 2000 from 2281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 400

Moving on to step 8:
When dividing 2818 by 400, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 142357.0
The remainder is 18 after subtracting 2800 from 2818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 400, we get 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 142357.0
Subtracting 0 from 180 leaves us 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.

Step 10:
400 can be fit into 1800 4 times, resulting in a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 142357.04
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.

Moving on to step 11:
2000 divided by 400 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 142357.045
Subtract 2000 from 2000 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.
Put 0 as the next digit of the answer. 
Result so far: 142357.045
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 400, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 142357.045
The remainder is 0 after subtracting 0 from 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 142357.045, and the remainder is 0.0.
