We're dividing 251935 by 86 
Let's see how many times 86 fits into 251935.

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
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 86

Advancing to step 2:
25 divided by 86 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 86

Let's proceed to step 3:
If we divide 251 by 86, we get 2 and a remainder of 79.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 172 from 251, we get 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 86

On to step 4:
86 goes into 799 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 774 away from 799, we end up with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 86

Going ahead to step 5:
If we divide 253 by 86, we get 2 and a remainder of 81.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
If we subtract 172 from 253, we get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 86

Advancing to step 6:
86 goes into 815 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 2929.0
Subtract 774 from 815 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
If we divide 410 by 86, we get 4 and a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 2929.4
Deduct 344 from 410 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
660 divided by 86 is 7 with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 2929.47
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 2929.476
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 2929.4767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 2929.47674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 2929.476744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 2929.476744 and a remainder of 1.6e-06.
