We're dividing 689454 by 40 
Our goal is to divide 689454 by 40.

Let's proceed to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 40

Moving on to step 2:
The number 40 fits into 68 1 times, leaving a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 40 from 68 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 40

Going ahead to step 3:
289 divided by 40 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 9 after subtracting 280 from 289.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 40

Moving on to step 4:
When dividing 94 by 40, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Deduct 80 from 94 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 40

On to step 5:
When dividing 145 by 40, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1723.0
Subtract 120 from 145 to get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 40

Let's proceed to step 6:
254 divided by 40 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 17236.0
Deduct 240 from 254 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
40 can be fit into 140 3 times, resulting in a remainder of 20.
The next digit of our result is 3. 
Result so far: 17236.3
Deduct 120 from 140 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
40 goes into 200 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17236.35
If we take 200 away from 200, 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.

Going ahead to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17236.35
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 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17236.35
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.

After the division, we end up with 17236.35 and a remainder of 0.0.
