188444 ÷ 21 
We want to figure out the number of times 188444 can be divided by 21.

Advancing to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 21

Advancing to step 2:
18 divided by 21 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 21

Advancing to step 3:
The number 21 fits into 188 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 20 after subtracting 168 from 188.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 21

Moving on to step 4:
21 goes into 204 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 15 after subtracting 189 from 204.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 21

Advancing to step 5:
21 can be fit into 154 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 897.0
Subtract 147 from 154 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 21

Let's proceed to step 6:
21 goes into 74 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 8973.0
If we take 63 away from 74, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8973.5
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8973.52
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 8973.523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8973.5238
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8973.5238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8973.523809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8973.5238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8973.52380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 8973.52380952 with a remainder of 8e-09.
