We're dividing 5175355 by 801 
Let's see how many times 801 fits into 5175355.

Going ahead to step 1:
The number 801 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 801

Going ahead to step 2:
51 divided by 801 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 801

Step 3:
517 divided by 801 is 0 with a remainder of 517.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 517, we end up with 517.
Append the next digit (5) from the dividend to 517 and continue with: 5175 / 801

On to step 4:
801 goes into 5175 6 times with a remainder of 369.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 4806 from 5175 and we're left with 369.
Bring next digit (3) of the dividend behind the 369 and repeat the process: 3693 / 801

Let's proceed to step 5:
3693 divided by 801 is 4 with a remainder of 489.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 3204 from 3693, we get 489.
Bring next digit (5) of the dividend behind the 489 and repeat the process: 4895 / 801

Advancing to step 6:
801 can be fit into 4895 6 times, resulting in a remainder of 89.
The number 6 becomes the next digit in our result. 
Result so far: 646.0
The remainder is 89 after subtracting 4806 from 4895.
Take the next digit (5) from the dividend and append it to 89, then repeat: 895 / 801

Going ahead to step 7:
895 divided by 801 is 1 with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 6461.0
If we subtract 801 from 895, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 8:
The number 801 fits into 940 1 times, leaving a remainder of 139.
Record the quotient 1 as the next digit in the result. 
Result so far: 6461.1
The remainder is 139 after subtracting 801 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
801 goes into 1390 1 times with a remainder of 589.
The next digit of our result is 1. 
Result so far: 6461.11
If we take 801 away from 1390, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

After the division, we end up with 6461.11 and a remainder of 0.589.
