Let's divide 898963 by 21
Let's see how many times 21 fits into 898963.

Let's proceed to step 1:
21 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 21

Moving on to step 2:
89 divided by 21 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 84 from 89 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 21

Advancing to step 3:
58 divided by 21 is 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 42 from 58, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 21

Let's proceed to step 4:
21 goes into 169 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 428.0
Deduct 168 from 169 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 21

Moving on to step 5:
When dividing 16 by 21, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 4280.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 21

On to step 6:
If we divide 163 by 21, we get 7 and a remainder of 16.
The next digit of our result is 7. 
Result so far: 42807.0
Subtract 147 from 163 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 42807.7
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.

Moving on to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 42807.76
Subtract 126 from 130 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.

Moving on to step 9:
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: 42807.761
Subtracting 21 from 40 leaves us 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.

Moving on to step 10:
If we divide 190 by 21, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 42807.7619
Deduct 189 from 190 and we're left 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.

Let's proceed to step 11:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 42807.7619
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.

Going ahead to step 12:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 42807.761904
Subtract 84 from 100 to get 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 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 42807.7619047
Subtracting 147 from 160 leaves us 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.

On to step 14:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 42807.76190476
If we subtract 126 from 130, we 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.

In conclusion, the division gives 42807.76190476 with a balance of 4e-09.
