Let's divide 958748 by 21
Let's see how many times 21 fits into 958748.

Going ahead to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 21

Advancing to step 2:
If we divide 95 by 21, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 95, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 21

Step 3:
118 divided by 21 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 105 from 118 and we're left with 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 21

Moving on to step 4:
21 goes into 137 6 times with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
Subtract 126 from 137 to get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 21

Moving on to step 5:
114 divided by 21 is 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 4565.0
Subtracting 105 from 114 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 21

Step 6:
When dividing 98 by 21, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 45654.0
Subtract 84 from 98 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 45654.6
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 45654.66
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 45654.66, and the remainder is 0.014.
