Let's divide 686170 by 20
Let's see how many times 20 fits into 686170.

Going ahead to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 20

Step 2:
When dividing 68 by 20, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 60 from 68, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 20

Let's proceed to step 3:
When dividing 86 by 20, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 80 from 86 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

On to step 4:
When dividing 61 by 20, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 343.0
The remainder is 1 after subtracting 60 from 61.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 20

Advancing to step 5:
When dividing 17 by 20, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 3430.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

Advancing to step 6:
170 divided by 20 is 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 34308.0
Subtracting 160 from 170 leaves us 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.

Step 7:
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: 34308.5
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.

Let's proceed to step 8:
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: 34308.5
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.

Advancing 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: 34308.5
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.

The final outcome is 34308.5, with a leftover of 0.0.
