We divide 66961111 by 72
The aim is to understand the frequency of 72 in 66961111.

Going ahead to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 72

Step 2:
If we divide 66 by 72, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 72

Going ahead to step 3:
If we divide 669 by 72, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 648 from 669 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 72

Let's proceed to step 4:
72 goes into 216 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we subtract 216 from 216, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 72

Step 5:
72 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 930.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 72

Going ahead to step 6:
The number 72 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 9300.0
If we subtract 0 from 11, we get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 72

Going ahead to step 7:
72 goes into 111 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 93001.0
Deduct 72 from 111 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 72

Step 8:
72 goes into 391 5 times with a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 930015.0
Deduct 360 from 391 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
310 divided by 72 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 930015.4
The remainder is 22 after subtracting 288 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
72 goes into 220 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 930015.43
If we take 216 away from 220, we end up 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.

Moving on to step 11:
If we divide 40 by 72, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 930015.43
Subtracting 0 from 40 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.

On to step 12:
72 can be fit into 400 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 930015.4305
If we take 360 away from 400, we end up 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.

Step 13:
400 divided by 72 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 930015.43055
If we take 360 away from 400, we end up 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.

In conclusion, the division gives 930015.43055 with a balance of 4e-05.
