We divide 983876 by 21
We want to divide 983876 by 21.

Moving on to step 1:
9 divided by 21 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 21

Going ahead to step 2:
The number 21 fits into 98 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 84 from 98 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 21

Let's proceed to step 3:
21 can be fit into 143 6 times, resulting in a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 126 from 143 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 21

Moving on to step 4:
If we divide 178 by 21, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 468.0
Deduct 168 from 178 and we're left with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 21

Step 5:
21 goes into 107 5 times with a remainder of 2.
The next digit of our result is 5. 
Result so far: 4685.0
The remainder is 2 after subtracting 105 from 107.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 21

On to step 6:
When dividing 26 by 21, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 46851.0
Deduct 21 from 26 and we're left with 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 7:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 46851.2
If we subtract 42 from 50, we 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.

Going ahead to step 8:
If we divide 80 by 21, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 46851.23
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 46851.238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 21, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 46851.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 46851.23809
If we take 189 away from 200, we end up 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.

Moving on to step 12:
110 divided by 21 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 46851.238095
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.

Going ahead to step 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 46851.2380952
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.

Let's proceed to step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 46851.23809523
Subtracting 63 from 80 leaves us 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.

The final result is 46851.23809523 with a remainder of 1.7e-08.
