We're dividing 740564 by 21 
We want to figure out the number of times 740564 can be divided by 21.

Going ahead to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 21

Advancing to step 2:
When dividing 74 by 21, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 63 from 74, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 21

Advancing to step 3:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 5 after subtracting 105 from 110.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

Advancing to step 4:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
If we take 42 away from 55, we end up with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 21

Step 5:
The number 21 fits into 136 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 3526.0
Subtract 126 from 136 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 21

Advancing to step 6:
The number 21 fits into 104 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 35264.0
Deduct 84 from 104 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.

On to step 7:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 35264.9
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
21 goes into 110 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 35264.95
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 21 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 35264.952
Subtract 42 from 50 to 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.

Advancing to step 10:
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: 35264.9523
If we subtract 63 from 80, we 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.

Going ahead to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 35264.95238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 35264.95238
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.

Step 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 35264.9523809
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
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: 35264.95238095
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.

After the division, we end up with 35264.95238095 and a remainder of 5e-09.
