897574 divided by 21 
We're looking to find how many times 21 goes into 897574.

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
If we take 0 away from 8, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Moving on to step 2:
89 divided by 21 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 84 from 89 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 21

Moving on to step 3:
21 can be fit into 57 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 42 from 57 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 21

Moving on to step 4:
155 divided by 21 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 427.0
Subtracting 147 from 155 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 21

Going ahead to step 5:
21 can be fit into 87 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 4274.0
Subtracting 84 from 87 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 21

Advancing to step 6:
The number 21 fits into 34 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 42741.0
Deduct 21 from 34 and we're left 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.

Advancing to step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 42741.6
Deduct 126 from 130 and we're left 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.

Let's proceed to step 8:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 42741.61
Subtract 21 from 40 to get 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 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 42741.619
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.

Moving on to step 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42741.619
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 11:
100 divided by 21 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 42741.61904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 42741.619047
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.

Going ahead to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 42741.6190476
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.

Advancing to step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 42741.61904761
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.

The final outcome is 42741.61904761, with a leftover of 1.9e-08.
