199468 ÷ 21 
We're looking to find how many times 21 goes into 199468.

On to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 21

Moving on to step 2:
19 divided by 21 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

Moving on to step 3:
The number 21 fits into 199 9 times, leaving a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 189 from 199 and we're left with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 21

Going ahead to step 4:
21 can be fit into 104 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Deduct 84 from 104 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 21

Let's proceed to step 5:
The number 21 fits into 206 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 949.0
Subtracting 189 from 206 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 21

Going ahead to step 6:
21 can be fit into 178 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 9498.0
The remainder is 10 after subtracting 168 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 21, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9498.4
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 9498.47
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 9498.476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 9498.4761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9498.47619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 9498.47619
If we take 0 away from 10, we end up 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 13:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9498.4761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 9498.47619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 9498.47619047 with a remainder of 1.3e-08.
