20622422 ÷ 400 
The aim is to understand the frequency of 400 in 20622422.

Moving on to step 1:
If we divide 2 by 400, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 400

Going ahead to step 2:
When dividing 20 by 400, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 400

Step 3:
When dividing 206 by 400, we get 0 with a remainder of 206.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 206, we get 206.
Append the next digit (2) from the dividend to 206 and continue with: 2062 / 400

On to step 4:
If we divide 2062 by 400, we get 5 and a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 2000 away from 2062, we end up with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 400

On to step 5:
400 goes into 622 1 times with a remainder of 222.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 400 away from 622, we end up with 222.
Include the next digit (4) from the dividend after 222, then repeat: 2224 / 400

Going ahead to step 6:
If we divide 2224 by 400, we get 5 and a remainder of 224.
The next digit of our result is 5. 
Result so far: 515.0
If we subtract 2000 from 2224, we get 224.
Grab the next digit (2) from the dividend, add it to 224, then carry on: 2242 / 400

Let's proceed to step 7:
If we divide 2242 by 400, we get 5 and a remainder of 242.
Record the quotient 5 as the next digit in the result. 
Result so far: 5155.0
If we subtract 2000 from 2242, we get 242.
Include the next digit (2) from the dividend after 242, then repeat: 2422 / 400

Step 8:
When dividing 2422 by 400, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 51556.0
If we subtract 2400 from 2422, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 400 is 0 with a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 51556.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
400 can be fit into 2200 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 51556.05
If we subtract 2000 from 2200, we 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.

Advancing to step 11:
The number 400 fits into 2000 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 51556.055
If we take 2000 away from 2000, 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 outcome is 51556.055, with a leftover of 0.0.
