We look at the division of 740801 by 21 
We want to divide 740801 by 21.

On to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 21

Advancing to step 2:
When dividing 74 by 21, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 63 from 74 to get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 21

On to step 3:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 105 from 110, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 21

Going ahead to step 4:
The number 21 fits into 58 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
If we take 42 away from 58, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 21

Going ahead to step 5:
If we divide 160 by 21, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 3527.0
If we subtract 147 from 160, we get 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 21

Going ahead to step 6:
131 divided by 21 is 6 with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 35276.0
The remainder is 5 after subtracting 126 from 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
When dividing 50 by 21, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 35276.2
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.

Moving on to step 8:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 35276.23
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 35276.238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
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: 35276.238
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.

Step 11:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 35276.23809
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 12:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35276.238095
Deduct 105 from 110 and we're left 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 13:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 35276.2380952
If we take 42 away from 50, we end up 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.

Going ahead to step 14:
21 goes into 80 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 35276.23809523
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.

Our division results in 35276.23809523 with a remaining 1.7e-08.
