Let's divide 903577 by 21
We want to divide 903577 by 21.

Let's proceed to step 1:
9 divided by 21 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 21

Let's proceed to step 2:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 84 away from 90, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 21

Moving on to step 3:
When dividing 63 by 21, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we take 63 away from 63, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 21

Going ahead to step 4:
21 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 430.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 21

Let's proceed to step 5:
57 divided by 21 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 4302.0
If we take 42 away from 57, we end up with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 21

Moving on to step 6:
When dividing 157 by 21, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 43027.0
Deduct 147 from 157 and we're left 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.

Let's proceed to step 7:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 43027.4
If we take 84 away from 100, we end up 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.

On to step 8:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 43027.47
The remainder is 13 after subtracting 147 from 160.
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 9:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 43027.476
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.

Step 10:
40 divided by 21 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 43027.4761
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.

Advancing to step 11:
If we divide 190 by 21, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 43027.47619
The remainder is 1 after subtracting 189 from 190.
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 12:
21 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43027.47619
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.

Step 13:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 43027.4761904
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.

Going ahead to step 14:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 43027.47619047
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.

The final result is 43027.47619047 with a remainder of 1.3e-08.
