We divide 908947 by 21
We're looking to find how many times 21 goes into 908947.

Moving on to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 21

Advancing to step 2:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 84 from 90 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 21

Advancing to step 3:
The number 21 fits into 68 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 63 from 68, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 21

Advancing to step 4:
If we divide 59 by 21, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 432.0
If we subtract 42 from 59, we get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 21

Going ahead to step 5:
When dividing 174 by 21, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4328.0
The remainder is 6 after subtracting 168 from 174.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 21

Let's proceed to step 6:
The number 21 fits into 67 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 43283.0
Subtract 63 from 67 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 43283.1
If we take 21 away from 40, we end up 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.

Going ahead to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 43283.19
Subtract 189 from 190 to 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 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 43283.19
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 43283.1904
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.

Moving on to step 11:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 43283.19047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43283.190476
Subtracting 126 from 130 leaves us 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.

Step 13:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 43283.1904761
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.

On to step 14:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 43283.19047619
If we take 189 away from 190, we end up 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.

In conclusion, the division gives 43283.19047619 with a balance of 1e-09.
