We look at the division of 871594 by 72 
We want to figure out the number of times 871594 can be divided by 72.

Let's proceed to step 1:
72 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 72

Going ahead to step 2:
72 can be fit into 87 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 72 from 87 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 72

Let's proceed to step 3:
If we divide 151 by 72, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 144 away from 151, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 72

On to step 4:
If we divide 75 by 72, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 72 from 75, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 72

Advancing to step 5:
72 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 1210.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 72

Going ahead to step 6:
When dividing 394 by 72, we get 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 12105.0
If we subtract 360 from 394, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
72 can be fit into 340 4 times, resulting in a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 12105.4
If we take 288 away from 340, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
When dividing 520 by 72, we get 7 with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 12105.47
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 12105.472
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 72, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12105.4722
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 12105.4722, with a leftover of 0.00016.
