840685 ÷ 25 
We're looking to find how many times 25 goes into 840685.

Step 1:
8 divided by 25 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 25

Advancing to step 2:
25 can be fit into 84 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 75 from 84 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 25

Let's proceed to step 3:
25 goes into 90 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 75 away from 90, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 25

Going ahead to step 4:
The number 25 fits into 156 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 336.0
If we take 150 away from 156, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 25

Let's proceed to step 5:
When dividing 68 by 25, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3362.0
Subtract 50 from 68 to get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 25

Moving on to step 6:
If we divide 185 by 25, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 33627.0
The remainder is 10 after subtracting 175 from 185.
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 7:
When dividing 100 by 25, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 33627.4
Deduct 100 from 100 and we're left 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 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33627.4
Subtract 0 from 0 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.

Advancing to step 9:
25 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 33627.4
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.

The final result is 33627.4 with a remainder of 0.0.
