Let's divide 309259 by 86
Let's see how many times 86 fits into 309259.

Step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 86

Let's proceed to step 2:
86 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 86

Step 3:
The number 86 fits into 309 3 times, leaving a remainder of 51.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 51 after subtracting 258 from 309.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 86

On to step 4:
86 goes into 512 5 times with a remainder of 82.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 430 from 512 leaves us with 82.
Include the next digit (5) from the dividend after 82, then repeat: 825 / 86

Moving on to step 5:
The number 86 fits into 825 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 359.0
Deduct 774 from 825 and we're left with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 86

Let's proceed to step 6:
519 divided by 86 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 3596.0
Subtracting 516 from 519 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 86, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 3596.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 86, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 3596.03
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
When dividing 420 by 86, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 3596.034
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
760 divided by 86 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 3596.0348
If we take 688 away from 760, we end up 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.

Let's proceed to step 11:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3596.03488
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.

After the division, we end up with 3596.03488 and a remainder of 3.2e-05.
