Let's divide 71805747 by 20
We want to divide 71805747 by 20.

Going ahead to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 20

Step 2:
20 can be fit into 71 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 71 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 20

Moving on to step 3:
20 goes into 118 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we subtract 100 from 118, we get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Step 4:
180 divided by 20 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 359.0
Deduct 180 from 180 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 20

Moving on to step 5:
20 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 3590.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 20

Going ahead to step 6:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 35902.0
Deduct 40 from 57 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 20

Moving on to step 7:
174 divided by 20 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 359028.0
Deduct 160 from 174 and we're left with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 20

Advancing to step 8:
20 goes into 147 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3590287.0
If we take 140 away from 147, we end up 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 9:
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: 3590287.3
Subtract 60 from 70 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 10:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3590287.35
If we subtract 100 from 100, we 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.

Advancing to step 11:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3590287.35
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3590287.35
If we subtract 0 from 0, we 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.

After the division, we end up with 3590287.35 and a remainder of 0.0.
