We divide 89210282 by 400
The aim is to understand the frequency of 400 in 89210282.

Let's proceed to step 1:
If we divide 8 by 400, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 400

Advancing to step 2:
400 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (2) from the dividend to 89 and continue with: 892 / 400

Advancing to step 3:
400 can be fit into 892 2 times, resulting in a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 800 from 892 and we're left with 92.
Grab the next digit (1) from the dividend, add it to 92, then carry on: 921 / 400

Going ahead to step 4:
If we divide 921 by 400, we get 2 and a remainder of 121.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 800 from 921 to get 121.
Bring next digit (0) of the dividend behind the 121 and repeat the process: 1210 / 400

Advancing to step 5:
If we divide 1210 by 400, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we take 1200 away from 1210, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 400

On to step 6:
When dividing 102 by 400, we get 0 with a remainder of 102.
Record the quotient 0 as the next digit in the result. 
Result so far: 2230.0
The remainder is 102 after subtracting 0 from 102.
Fetch the next digit (8) from the dividend, attach it to 102 and continue: 1028 / 400

Moving on to step 7:
If we divide 1028 by 400, we get 2 and a remainder of 228.
Write down 2 as next digit of the result. 
Result so far: 22302.0
Subtract 800 from 1028 to get 228.
Take the next digit (2) from the dividend and append it to 228, then repeat: 2282 / 400

Let's proceed to step 8:
If we divide 2282 by 400, we get 5 and a remainder of 282.
Put 5 as the next digit of the answer. 
Result so far: 223025.0
Deduct 2000 from 2282 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 9:
The number 400 fits into 2820 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 223025.7
Deduct 2800 from 2820 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
400 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 223025.7
The remainder is 200 after subtracting 0 from 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:
If we divide 2000 by 400, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 223025.705
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.

Moving on to step 12:
If we divide 0 by 400, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 223025.705
Deduct 0 from 0 and we're left 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.

Let's proceed to step 13:
The number 400 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 223025.705
Subtracting 0 from 0 leaves us 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.

Our division results in 223025.705 with a remaining 0.0.
