We're dividing 869975 by 72 
We're looking to find how many times 72 goes into 869975.

Step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 72

Advancing to step 2:
86 divided by 72 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 72 from 86 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 72

Let's proceed to step 3:
The number 72 fits into 149 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 144 from 149 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 72

Step 4:
72 goes into 59 0 times with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtract 0 from 59 to get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 72

Going ahead to step 5:
When dividing 597 by 72, we get 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 1208.0
If we take 576 away from 597, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 72

Advancing to step 6:
If we divide 215 by 72, we get 2 and a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 12082.0
Subtract 144 from 215 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
If we divide 710 by 72, we get 9 and a remainder of 62.
The next digit of our result is 9. 
Result so far: 12082.9
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
72 can be fit into 620 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 12082.98
Subtracting 576 from 620 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 72, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 12082.986
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 72 fits into 80 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 12082.9861
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
80 divided by 72 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 12082.98611
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 12082.98611 with a remaining 8e-06.
