245817 divided by 86 
We're looking to find how many times 86 goes into 245817.

Going ahead to step 1:
2 divided by 86 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 86

Moving on to step 2:
When dividing 24 by 86, we get 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 86

Step 3:
86 can be fit into 245 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 73 after subtracting 172 from 245.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 86

Advancing to step 4:
If we divide 738 by 86, we get 8 and a remainder of 50.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 688 from 738 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 86

On to step 5:
86 can be fit into 501 5 times, resulting in a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
If we subtract 430 from 501, we get 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 86

Step 6:
86 goes into 717 8 times with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 2858.0
Deduct 688 from 717 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 86 fits into 290 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 2858.3
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
86 goes into 320 3 times with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 2858.33
Subtract 258 from 320 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 2858.33, with a leftover of 0.062.
