We look at the division of 557790 by 86 
We want to divide 557790 by 86.

Advancing to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 86

Let's proceed to step 2:
86 can be fit into 55 0 times, resulting in a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 86

Moving on to step 3:
86 can be fit into 557 6 times, resulting in a remainder of 41.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 516 from 557 and we're left with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 86

Moving on to step 4:
86 can be fit into 417 4 times, resulting in a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 344 from 417 and we're left with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 86

Step 5:
739 divided by 86 is 8 with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 648.0
Subtracting 688 from 739 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 86

Let's proceed to step 6:
86 goes into 510 5 times with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 6485.0
Deduct 430 from 510 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 7:
86 goes into 800 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 6485.9
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 6485.93
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 6485.93
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6485.9302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
When dividing 280 by 86, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 6485.93023
If we take 258 away from 280, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 6485.930232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 6485.9302325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 6485.93023255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 6485.93023255, with a leftover of 7e-08.
