We're dividing 974028 by 21 
Let's see how many times 21 fits into 974028.

Step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 21

On to step 2:
If we divide 97 by 21, we get 4 and a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 84 away from 97, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 21

Advancing to step 3:
The number 21 fits into 134 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 8 after subtracting 126 from 134.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 21

Going ahead to step 4:
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: 463.0
If we take 63 away from 80, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 21

Advancing to step 5:
21 can be fit into 172 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4638.0
The remainder is 4 after subtracting 168 from 172.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 21

Moving on to step 6:
21 goes into 48 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 46382.0
The remainder is 6 after subtracting 42 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 46382.2
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 46382.28
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 21, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 46382.285
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 46382.2857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 46382.28571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 46382.285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 46382.2857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
180 divided by 21 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 46382.28571428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 46382.28571428, with a leftover of 1.2e-08.
