633898 ÷ 21 
We want to divide 633898 by 21.

Step 1:
When dividing 6 by 21, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 21

Step 2:
21 goes into 63 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 0 after subtracting 63 from 63.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 21

Let's proceed to step 3:
If we divide 3 by 21, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Moving on to step 4:
When dividing 38 by 21, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 301.0
Subtracting 21 from 38 leaves us with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 21

Step 5:
When dividing 179 by 21, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 3018.0
Subtracting 168 from 179 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 21

Advancing to step 6:
118 divided by 21 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 30185.0
The remainder is 13 after subtracting 105 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 30185.6
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.

Advancing to step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 30185.61
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 9:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 30185.619
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.

Going ahead to step 10:
21 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 30185.619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 30185.61904
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.

Moving on to step 12:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 30185.619047
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.

Let's proceed to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 30185.6190476
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.

Going ahead to step 14:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 30185.61904761
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.

The quotient of the division is 30185.61904761, and the remainder is 1.9e-08.
