186422 ÷ 20 
Let's see how many times 20 fits into 186422.

On to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 20

Advancing to step 2:
If we divide 18 by 20, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 20

Step 3:
20 goes into 186 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 180 away from 186, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

On to step 4:
When dividing 64 by 20, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 93.0
The remainder is 4 after subtracting 60 from 64.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Going ahead to step 5:
If we divide 42 by 20, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 932.0
The remainder is 2 after subtracting 40 from 42.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 20

Let's proceed to step 6:
20 can be fit into 22 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 9321.0
If we subtract 20 from 22, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 20 fits into 20 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 9321.1
If we subtract 20 from 20, we 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9321.1
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 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9321.1
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 9321.1 with a remaining 0.0.
