We look at the division of 735987 by 20 
We want to divide 735987 by 20.

Advancing to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 20

On to step 2:
The number 20 fits into 73 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 60 away from 73, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 20

Let's proceed to step 3:
When dividing 135 by 20, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtract 120 from 135 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

Step 4:
When dividing 159 by 20, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 367.0
If we take 140 away from 159, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 20

Step 5:
When dividing 198 by 20, we get 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 3679.0
The remainder is 18 after subtracting 180 from 198.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 20

On 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: 36799.0
Subtracting 180 from 187 leaves us 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.

Step 7:
20 can be fit into 70 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 36799.3
If we take 60 away from 70, we end up 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 36799.35
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36799.35
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.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36799.35
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.

The final outcome is 36799.35, with a leftover of 0.0.
