253145 divided by 86 
We want to figure out the number of times 253145 can be divided by 86.

Advancing to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 86

Moving on to step 2:
25 divided by 86 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 86

On to step 3:
When dividing 253 by 86, we get 2 with a remainder of 81.
The next digit of our result is 2. 
Result so far: 2.0
If we take 172 away from 253, we end up with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 86

Moving on to step 4:
If we divide 811 by 86, we get 9 and a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 774 from 811, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 86

Going ahead to step 5:
When dividing 374 by 86, we get 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
If we subtract 344 from 374, we get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 86

Let's proceed to step 6:
86 goes into 305 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 2943.0
If we subtract 258 from 305, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
When dividing 470 by 86, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 2943.5
Subtracting 430 from 470 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2943.54
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
If we divide 560 by 86, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 2943.546
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 86, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2943.5465
Deduct 430 from 440 and we're left with 10.
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 11:
86 goes into 100 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 2943.54651
Subtracting 86 from 100 leaves us 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 12:
When dividing 140 by 86, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 2943.546511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 2943.546511 with a remainder of 5.4e-06.
