17406247 ÷ 285 
Let's see how many times 285 fits into 17406247.

Step 1:
If we divide 1 by 285, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 285

Going ahead to step 2:
If we divide 17 by 285, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 285

Moving on to step 3:
The number 285 fits into 174 0 times, leaving a remainder of 174.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 174, we get 174.
Fetch the next digit (0) from the dividend, attach it to 174 and continue: 1740 / 285

Advancing to step 4:
When dividing 1740 by 285, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 1710 from 1740 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 285

Let's proceed to step 5:
285 can be fit into 306 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 61.0
Subtract 285 from 306 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 285

Let's proceed to step 6:
When dividing 212 by 285, we get 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 610.0
The remainder is 212 after subtracting 0 from 212.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 285

Going ahead to step 7:
285 can be fit into 2124 7 times, resulting in a remainder of 129.
The next digit of our result is 7. 
Result so far: 6107.0
Deduct 1995 from 2124 and we're left with 129.
Append the next digit (7) from the dividend to 129 and continue with: 1297 / 285

On to step 8:
The number 285 fits into 1297 4 times, leaving a remainder of 157.
Put 4 as the next digit of the answer. 
Result so far: 61074.0
If we take 1140 away from 1297, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 9:
285 goes into 1570 5 times with a remainder of 145.
Use 5 as the next digit of our solution. 
Result so far: 61074.5
Subtracting 1425 from 1570 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 10:
When dividing 1450 by 285, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 61074.55
The remainder is 25 after subtracting 1425 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 61074.55, with a leftover of 0.025.
