507788 ÷ 86 
We're looking to find how many times 86 goes into 507788.

On to step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 86

Advancing to step 2:
The number 86 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 86

Going ahead to step 3:
The number 86 fits into 507 5 times, leaving a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 430 from 507, we get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 86

On to step 4:
The number 86 fits into 777 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we subtract 774 from 777, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 86

Advancing to step 5:
86 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 590.0
Subtract 0 from 38 to get 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 86

On to step 6:
86 goes into 388 4 times with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 5904.0
If we take 344 away from 388, we end up 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.

Let's proceed to step 7:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5904.5
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 5904.51
If we take 86 away from 100, we end up 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.

Step 9:
When dividing 140 by 86, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 5904.511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 5904.511 and a remainder of 0.0054.
