Let's divide 18805532 by 400
The aim is to understand the frequency of 400 in 18805532.

Advancing to step 1:
If we divide 1 by 400, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 400

Going ahead to step 2:
If we divide 18 by 400, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 400

Advancing to step 3:
The number 400 fits into 188 0 times, leaving a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 188 after subtracting 0 from 188.
Grab the next digit (0) from the dividend, add it to 188, then carry on: 1880 / 400

On to step 4:
400 can be fit into 1880 4 times, resulting in a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1600 from 1880 and we're left with 280.
Append the next digit (5) from the dividend to 280 and continue with: 2805 / 400

Advancing to step 5:
When dividing 2805 by 400, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 5 after subtracting 2800 from 2805.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 400

On to step 6:
The number 400 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 470.0
If we subtract 0 from 55, we get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 400

Moving on to step 7:
The number 400 fits into 553 1 times, leaving a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 4701.0
If we subtract 400 from 553, we get 153.
Append the next digit (2) from the dividend to 153 and continue with: 1532 / 400

Going ahead to step 8:
The number 400 fits into 1532 3 times, leaving a remainder of 332.
The number 3 becomes the next digit in our result. 
Result so far: 47013.0
Subtract 1200 from 1532 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 9:
400 can be fit into 3320 8 times, resulting in a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 47013.8
If we subtract 3200 from 3320, 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.

Moving on to step 10:
The number 400 fits into 1200 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 47013.83
Subtracting 1200 from 1200 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.

Step 11:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47013.83
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.

On to step 12:
400 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 47013.83
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.

After the division, we end up with 47013.83 and a remainder of 0.0.
