Let's divide 861288 by 73
We want to divide 861288 by 73.

Going ahead to step 1:
73 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 73

Let's proceed to step 2:
73 can be fit into 86 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 73 from 86 to get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 73

Advancing to step 3:
The number 73 fits into 131 1 times, leaving a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 73 from 131 leaves us with 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 73

Moving on to step 4:
73 goes into 582 7 times with a remainder of 71.
The next digit of our result is 7. 
Result so far: 117.0
Subtract 511 from 582 to get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 73

Let's proceed to step 5:
When dividing 718 by 73, we get 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 1179.0
Deduct 657 from 718 and we're left with 61.
Append the next digit (8) from the dividend to 61 and continue with: 618 / 73

Advancing to step 6:
If we divide 618 by 73, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 11798.0
If we take 584 away from 618, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 73, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 11798.4
If we take 292 away from 340, 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.

Going ahead to step 8:
480 divided by 73 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 11798.46
Deduct 438 from 480 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
420 divided by 73 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 11798.465
Subtracting 365 from 420 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
550 divided by 73 is 7 with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 11798.4657
Subtracting 511 from 550 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
The number 73 fits into 390 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 11798.46575
Subtracting 365 from 390 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
If we divide 250 by 73, we get 3 and a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 11798.465753
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 73 fits into 310 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 11798.4657534
If we subtract 292 from 310, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
73 can be fit into 180 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 11798.46575342
The remainder is 34 after subtracting 146 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 11798.46575342 and a remainder of 3.4e-08.
