180859 ÷ 72 
We're looking to find how many times 72 goes into 180859.

On to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 72

On to step 2:
If we divide 18 by 72, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 72

Advancing to step 3:
If we divide 180 by 72, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 144 from 180 to get 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 72

Advancing to step 4:
72 can be fit into 368 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 360 from 368 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 72

Going ahead to step 5:
When dividing 85 by 72, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 251.0
Subtracting 72 from 85 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 72

Going ahead to step 6:
When dividing 139 by 72, we get 1 with a remainder of 67.
The next digit of our result is 1. 
Result so far: 2511.0
The remainder is 67 after subtracting 72 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
72 can be fit into 670 9 times, resulting in a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 2511.9
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
72 goes into 220 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 2511.93
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 72, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2511.93
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 72 is 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 2511.9305
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
72 goes into 400 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 2511.93055
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 2511.93055, and the remainder is 4e-05.
