We divide 921163 by 21
Our goal is to divide 921163 by 21.

Going ahead to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 21

Moving on to step 2:
The number 21 fits into 92 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 92 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 21

Let's proceed to step 3:
When dividing 81 by 21, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 63 from 81 leaves us with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 21

Going ahead to step 4:
If we divide 181 by 21, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 438.0
Subtract 168 from 181 to get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 21

Going ahead to step 5:
21 goes into 136 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 4386.0
Subtracting 126 from 136 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 21

Going ahead to step 6:
The number 21 fits into 103 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 43864.0
The remainder is 19 after subtracting 84 from 103.
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 7:
190 divided by 21 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 43864.9
Deduct 189 from 190 and we're left 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.

Going ahead to step 8:
If we divide 10 by 21, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 43864.9
If we take 0 away from 10, we end up 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.

Step 9:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 43864.904
Subtracting 84 from 100 leaves us 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.

Step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 43864.9047
If we subtract 147 from 160, we 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.

Going ahead to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 43864.90476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 43864.904761
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.

Advancing to step 13:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 43864.9047619
Deduct 189 from 190 and we're left 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.

Let's proceed to step 14:
10 divided by 21 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 43864.9047619
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.

The final outcome is 43864.9047619, with a leftover of 1e-08.
