We divide 88529201 by 400
The aim is to understand the frequency of 400 in 88529201.

Moving on to step 1:
If we divide 8 by 400, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 400

Let's proceed to step 2:
If we divide 88 by 400, we get 0 and a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (5) from the dividend and append it to 88, then repeat: 885 / 400

Advancing to step 3:
When dividing 885 by 400, we get 2 with a remainder of 85.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 800 away from 885, we end up with 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 400

Advancing to step 4:
When dividing 852 by 400, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 800 away from 852, we end up with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 400

On to step 5:
400 can be fit into 529 1 times, resulting in a remainder of 129.
The next digit of our result is 1. 
Result so far: 221.0
If we take 400 away from 529, we end up with 129.
Bring next digit (2) of the dividend behind the 129 and repeat the process: 1292 / 400

Going ahead to step 6:
1292 divided by 400 is 3 with a remainder of 92.
Record the quotient 3 as the next digit in the result. 
Result so far: 2213.0
If we subtract 1200 from 1292, we get 92.
Bring next digit (0) of the dividend behind the 92 and repeat the process: 920 / 400

Advancing to step 7:
920 divided by 400 is 2 with a remainder of 120.
The next digit of our result is 2. 
Result so far: 22132.0
Deduct 800 from 920 and we're left with 120.
Include the next digit (1) from the dividend after 120, then repeat: 1201 / 400

On to step 8:
When dividing 1201 by 400, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 221323.0
Deduct 1200 from 1201 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
400 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 221323.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 400, we get 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 221323.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 221323.0 with a remaining 0.1.
