905218 divided by 21 
Our goal is to divide 905218 by 21.

Moving on to step 1:
21 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 21

Going ahead to step 2:
90 divided by 21 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 84 from 90 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

On to step 3:
21 goes into 65 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 63 from 65 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

On to step 4:
21 goes into 22 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 431.0
If we take 21 away from 22, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 21

On to step 5:
The number 21 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 4310.0
If we take 0 away from 11, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 21

On to step 6:
The number 21 fits into 118 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 43105.0
Subtract 105 from 118 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 7:
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: 43105.6
If we take 126 away from 130, we end up 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.

Step 8:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 43105.61
Deduct 21 from 40 and we're left 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.

Step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 43105.619
Subtract 189 from 190 to 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.

On to step 10:
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: 43105.619
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.

Going ahead to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 43105.61904
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.

Advancing to step 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 43105.619047
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.

Step 13:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 43105.6190476
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.

Step 14:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 43105.61904761
Deduct 21 from 40 and we're left 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 43105.61904761, and the remainder is 1.9e-08.
