We divide 736587 by 20
We want to figure out the number of times 736587 can be divided by 20.

Step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 20

Step 2:
20 goes into 73 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 73 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 20

On to step 3:
20 can be fit into 136 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 120 from 136, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 20

On to step 4:
The number 20 fits into 165 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Subtracting 160 from 165 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Step 5:
20 can be fit into 58 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3682.0
Deduct 40 from 58 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 20

Going ahead to step 6:
20 goes into 187 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 36829.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 20 fits into 70 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 36829.3
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 36829.35
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36829.35
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36829.35
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 36829.35 and a remainder of 0.0.
