910361 divided by 21 
Our goal is to divide 910361 by 21.

Going ahead to step 1:
The number 21 fits into 9 0 times, leaving 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.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 21

Let's proceed to step 2:
91 divided by 21 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 84 from 91 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 21

On to step 3:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 63 from 70 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 21

Going ahead to step 4:
73 divided by 21 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 433.0
If we take 63 away from 73, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 21

Step 5:
21 can be fit into 106 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 4335.0
The remainder is 1 after subtracting 105 from 106.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 21

Moving on to step 6:
If we divide 11 by 21, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 43350.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 43350.5
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 43350.52
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 21, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 43350.523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 43350.5238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 43350.5238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 21, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 43350.523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 43350.5238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
21 goes into 50 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 43350.52380952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 43350.52380952, and the remainder is 8e-09.
