Let's divide 874376 by 21
We want to divide 874376 by 21.

On to step 1:
21 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 21

Moving on to step 2:
If we divide 87 by 21, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 84 from 87 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 21

Going ahead to step 3:
34 divided by 21 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 21 from 34, we get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 21

On to step 4:
When dividing 133 by 21, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 416.0
If we take 126 away from 133, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 21

On to step 5:
77 divided by 21 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 4163.0
If we subtract 63 from 77, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 21

Going ahead to step 6:
21 can be fit into 146 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 41636.0
Subtract 126 from 146 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:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 41636.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
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: 41636.95
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.

Let's proceed to step 9:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 41636.952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 41636.9523
Subtract 63 from 80 to 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 11:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 41636.95238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 41636.95238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 21 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 41636.9523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
21 goes into 110 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 41636.95238095
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.

The final result is 41636.95238095 with a remainder of 5e-09.
