245913 ÷ 86 
We want to divide 245913 by 86.

Advancing to step 1:
The number 86 fits into 2 0 times, leaving 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.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 86

Step 2:
86 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 86

On to step 3:
If we divide 245 by 86, we get 2 and a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 172 from 245 leaves us with 73.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 86

Going ahead to step 4:
The number 86 fits into 739 8 times, leaving a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 688 from 739 to get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 86

Step 5:
86 can be fit into 511 5 times, resulting in a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 285.0
Subtracting 430 from 511 leaves us with 81.
Include the next digit (3) from the dividend after 81, then repeat: 813 / 86

Let's proceed to step 6:
When dividing 813 by 86, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 2859.0
Deduct 774 from 813 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
The number 86 fits into 390 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 2859.4
If we subtract 344 from 390, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2859.45
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
86 goes into 300 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 2859.453
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
86 goes into 420 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 2859.4534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 2859.45348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 2859.453488
Deduct 688 from 720 and we're left 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.

The final outcome is 2859.453488, with a leftover of 3.2e-06.
