691171 ÷ 20 
We're looking to find how many times 20 goes into 691171.

On to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 20

Step 2:
If we divide 69 by 20, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 9 after subtracting 60 from 69.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Step 3:
20 can be fit into 91 4 times, resulting in a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 80 away from 91, we end up with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 20

Step 4:
When dividing 111 by 20, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 345.0
The remainder is 11 after subtracting 100 from 111.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 20

Let's proceed to step 5:
When dividing 117 by 20, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 3455.0
Subtract 100 from 117 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 20

Advancing to step 6:
20 can be fit into 171 8 times, resulting in a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 34558.0
Subtracting 160 from 171 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 34558.5
If we subtract 100 from 110, we 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.

On 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: 34558.55
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.

Our division results in 34558.55 with a remaining 0.0.
