718843 ÷ 20 
Our goal is to divide 718843 by 20.

Step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 20

Advancing to step 2:
If we divide 71 by 20, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 71 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 20

On to step 3:
118 divided by 20 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 100 from 118 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 20

Advancing to step 4:
20 can be fit into 188 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 359.0
Deduct 180 from 188 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

Moving on to step 5:
84 divided by 20 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 3594.0
If we subtract 80 from 84, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

Advancing to step 6:
If we divide 43 by 20, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 35942.0
The remainder is 3 after subtracting 40 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 20 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 35942.1
If we take 20 away from 30, 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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 35942.15
Subtracting 100 from 100 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35942.15
If we take 0 away from 0, we end up 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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35942.15
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 quotient of the division is 35942.15, and the remainder is 0.0.
