70722 ÷ 20 
We're looking to find how many times 20 goes into 70722.

Step 1:
If we divide 7 by 20, we get 0 and 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.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Advancing to step 2:
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: 3.0
Deduct 60 from 70 and we're left with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 20

Let's proceed to step 3:
When dividing 107 by 20, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 100 from 107 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

Step 4:
If we divide 72 by 20, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
If we subtract 60 from 72, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 20

Moving on to step 5:
20 can be fit into 122 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3536.0
If we take 120 away from 122, 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.

Let's proceed to step 6:
The number 20 fits into 20 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 3536.1
Subtract 20 from 20 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 7:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3536.1
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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3536.1
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.

Our division results in 3536.1 with a remaining 0.0.
