We're dividing 846402 by 72 
Let's see how many times 72 fits into 846402.

Advancing to step 1:
72 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 72

Let's proceed to step 2:
72 goes into 84 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 72 from 84 and we're left with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 72

Going ahead to step 3:
The number 72 fits into 126 1 times, leaving a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 72 away from 126, we end up with 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 72

Going ahead to step 4:
When dividing 544 by 72, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 504 from 544, we get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 72

Moving on to step 5:
If we divide 400 by 72, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 1175.0
If we subtract 360 from 400, we get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 72

Advancing to step 6:
402 divided by 72 is 5 with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 11755.0
Deduct 360 from 402 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.

Let's proceed to step 7:
The number 72 fits into 420 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 11755.5
Subtracting 360 from 420 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 72 fits into 600 8 times, leaving a remainder of 24.
The next digit of our result is 8. 
Result so far: 11755.58
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
If we divide 240 by 72, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 11755.583
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 11755.5833
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 11755.5833, with a leftover of 0.00024.
