We divide 980863 by 21
Let's see how many times 21 fits into 980863.

Moving on 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
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 21

Advancing to step 2:
When dividing 98 by 21, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 14 after subtracting 84 from 98.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 21

Moving on to step 3:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 46.0
Deduct 126 from 140 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 21

Advancing to step 4:
21 can be fit into 148 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 467.0
Subtracting 147 from 148 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

Advancing to step 5:
If we divide 16 by 21, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 4670.0
Subtract 0 from 16 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 21

On to step 6:
If we divide 163 by 21, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 46707.0
Deduct 147 from 163 and we're left 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 7:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 46707.7
If we take 147 away from 160, we end up 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.

On to step 8:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 46707.76
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.

Advancing to step 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 46707.761
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.

Going ahead to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 46707.7619
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 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 46707.7619
Subtracting 0 from 10 leaves us 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.

Advancing to step 12:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 46707.761904
Deduct 84 from 100 and we're left 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 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 46707.7619047
Deduct 147 from 160 and we're left 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.

Step 14:
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: 46707.76190476
Subtract 126 from 130 to 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.

The final result is 46707.76190476 with a remainder of 4e-09.
