We divide 42270774 by 400
The aim is to understand the frequency of 400 in 42270774.

Advancing to step 1:
The number 400 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 400

On to step 2:
If we divide 42 by 400, we get 0 and a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 400

On to step 3:
When dividing 422 by 400, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 400 from 422 and we're left with 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 400

On to step 4:
When dividing 227 by 400, we get 0 with a remainder of 227.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 227 and we're left with 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 400

Advancing to step 5:
400 goes into 2270 5 times with a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we subtract 2000 from 2270, we get 270.
Fetch the next digit (7) from the dividend, attach it to 270 and continue: 2707 / 400

Moving on to step 6:
400 can be fit into 2707 6 times, resulting in a remainder of 307.
The next digit of our result is 6. 
Result so far: 1056.0
If we subtract 2400 from 2707, we get 307.
Take the next digit (7) from the dividend and append it to 307, then repeat: 3077 / 400

Going ahead to step 7:
The number 400 fits into 3077 7 times, leaving a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 10567.0
Deduct 2800 from 3077 and we're left with 277.
Include the next digit (4) from the dividend after 277, then repeat: 2774 / 400

On to step 8:
The number 400 fits into 2774 6 times, leaving a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 105676.0
If we subtract 2400 from 2774, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 9:
When dividing 3740 by 400, we get 9 with a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 105676.9
Subtracting 3600 from 3740 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
1400 divided by 400 is 3 with a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 105676.93
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.

Moving on to step 11:
When dividing 2000 by 400, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 105676.935
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.

Going ahead to step 12:
0 divided by 400 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 105676.935
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.

Let's proceed to step 13:
When dividing 0 by 400, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 105676.935
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 final result is 105676.935 with a remainder of 0.0.
