We're dividing 218221 by 72 
We want to figure out the number of times 218221 can be divided by 72.

Advancing to step 1:
When dividing 2 by 72, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 72

Advancing to step 2:
When dividing 21 by 72, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 72

Moving on to step 3:
The number 72 fits into 218 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 216 away from 218, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 72

Going ahead to step 4:
72 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 22 to get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 72

Step 5:
222 divided by 72 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 303.0
If we take 216 away from 222, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 72

On to step 6:
72 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 3030.0
If we subtract 0 from 61, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
If we divide 610 by 72, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 3030.8
If we take 576 away from 610, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 72, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 3030.84
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.

Moving on to step 9:
If we divide 520 by 72, we get 7 and a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 3030.847
Subtract 504 from 520 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.

Going ahead to step 10:
160 divided by 72 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3030.8472
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 11:
160 divided by 72 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 3030.84722
If we subtract 144 from 160, we 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.

Our division results in 3030.84722 with a remaining 1.6e-05.
