We look at the division of 980734 by 21 
We want to figure out the number of times 980734 can be divided by 21.

On to step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 21

Step 2:
When dividing 98 by 21, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 98 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 21

Moving on to step 3:
If we divide 140 by 21, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 126 away from 140, we end up with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 21

Moving on to step 4:
If we divide 147 by 21, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 467.0
The remainder is 0 after subtracting 147 from 147.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 21

Moving on to step 5:
21 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 4670.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 21

Moving on to step 6:
21 can be fit into 34 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 46701.0
If we take 21 away from 34, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 21 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 46701.6
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 46701.61
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 46701.619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 46701.619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 46701.61904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
The number 21 fits into 160 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 46701.619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 46701.6190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 46701.61904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 46701.61904761, and the remainder is 1.9e-08.
