Let's divide 897885 by 21
We want to figure out the number of times 897885 can be divided by 21.

Moving on to step 1:
When dividing 8 by 21, we get 0 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.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 21

Step 2:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 84 away from 89, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

On to step 3:
When dividing 57 by 21, we get 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 42 from 57 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 21

Let's proceed to step 4:
21 can be fit into 158 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Deduct 147 from 158 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 21

Advancing to step 5:
The number 21 fits into 118 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 4275.0
The remainder is 13 after subtracting 105 from 118.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 21

Let's proceed to step 6:
21 can be fit into 135 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 42756.0
If we subtract 126 from 135, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
21 goes into 90 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 42756.4
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
21 goes into 60 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 42756.42
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 42756.428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 42756.4285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
21 goes into 150 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 42756.42857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 42756.428571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 42756.4285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
60 divided by 21 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 42756.42857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 42756.42857142 and a remainder of 1.8e-08.
