We're dividing 870464 by 73 
We want to divide 870464 by 73.

Moving on to step 1:
73 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 73

Let's proceed to step 2:
73 can be fit into 87 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 73 from 87 to get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 73

Going ahead to step 3:
140 divided by 73 is 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 73 from 140 and we're left with 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 73

Step 4:
674 divided by 73 is 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 657 from 674, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 73

Moving on to step 5:
The number 73 fits into 176 2 times, leaving a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 1192.0
Subtract 146 from 176 to get 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 73

Moving on to step 6:
304 divided by 73 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11924.0
The remainder is 12 after subtracting 292 from 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
73 can be fit into 120 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 11924.1
Subtract 73 from 120 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
If we divide 470 by 73, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11924.16
Subtracting 438 from 470 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 73 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11924.164
Subtracting 292 from 320 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 73 is 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 11924.1643
The remainder is 61 after subtracting 219 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 11:
The number 73 fits into 610 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 11924.16438
If we take 584 away from 610, we end up 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.

Let's proceed to step 12:
When dividing 260 by 73, we get 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 11924.164383
Subtracting 219 from 260 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
If we divide 410 by 73, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 11924.1643835
If we subtract 365 from 410, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
73 goes into 450 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 11924.16438356
Subtracting 438 from 450 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 11924.16438356, with a leftover of 1.2e-08.
