689456 divided by 20 
We're looking to find how many times 20 goes into 689456.

Advancing to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 20

Advancing to step 2:
68 divided by 20 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 60 from 68 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 20

On to step 3:
If we divide 89 by 20, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 20

Moving on to step 4:
94 divided by 20 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 344.0
Deduct 80 from 94 and we're left with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 20

On to step 5:
145 divided by 20 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 3447.0
The remainder is 5 after subtracting 140 from 145.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 20

Advancing to step 6:
The number 20 fits into 56 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 34472.0
If we take 40 away from 56, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 34472.8
If we take 160 away from 160, 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 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 34472.8
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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34472.8
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.

After the division, we end up with 34472.8 and a remainder of 0.0.
