Let's divide 603346 by 86
We want to divide 603346 by 86.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 86

Step 2:
If we divide 60 by 86, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 60 to get 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 86

Advancing to step 3:
86 goes into 603 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 1 after subtracting 602 from 603.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 86

Going ahead to step 4:
86 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we take 0 away from 13, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 86

Advancing to step 5:
86 goes into 134 1 times with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 701.0
Deduct 86 from 134 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 86

Step 6:
If we divide 486 by 86, we get 5 and a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 7015.0
If we take 430 away from 486, we end up with 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 7:
560 divided by 86 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 7015.6
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
440 divided by 86 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 7015.65
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 9:
86 can be fit into 100 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 7015.651
Subtract 86 from 100 to get 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 10:
86 goes into 140 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 7015.6511
If we subtract 86 from 140, we 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.

The quotient of the division is 7015.6511, and the remainder is 0.00054.
