962849 ÷ 21 
Our goal is to divide 962849 by 21.

Moving on to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 21

Advancing to step 2:
21 can be fit into 96 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 84 from 96 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 21

Advancing to step 3:
When dividing 122 by 21, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 17 after subtracting 105 from 122.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 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: 458.0
Deduct 168 from 178 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 21

Going ahead to step 5:
104 divided by 21 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4584.0
If we take 84 away from 104, we end up with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 21

Going ahead to step 6:
21 goes into 209 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 45849.0
Subtract 189 from 209 to get 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 7:
21 goes into 200 9 times with a remainder of 11.
The next digit of our result is 9. 
Result so far: 45849.9
Subtracting 189 from 200 leaves us 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.

Going ahead to step 8:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45849.95
Subtracting 105 from 110 leaves us 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.

Going ahead to step 9:
50 divided by 21 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 45849.952
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.

Let's proceed to step 10:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 45849.9523
The remainder is 17 after subtracting 63 from 80.
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 11:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 45849.95238
Subtracting 168 from 170 leaves us 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 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 45849.95238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
21 can be fit into 200 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 45849.9523809
Subtracting 189 from 200 leaves us 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.

Step 14:
If we divide 110 by 21, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45849.95238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 45849.95238095 with a remaining 5e-09.
