963577 ÷ 72 
The aim is to understand the frequency of 72 in 963577.

Step 1:
The number 72 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 72

Going ahead to step 2:
If we divide 96 by 72, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 72 from 96 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 72

Advancing to step 3:
243 divided by 72 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 216 from 243 leaves us with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 72

Moving on to step 4:
72 goes into 275 3 times with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 133.0
The remainder is 59 after subtracting 216 from 275.
Take the next digit (7) from the dividend and append it to 59, then repeat: 597 / 72

Going ahead to step 5:
597 divided by 72 is 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 1338.0
Deduct 576 from 597 and we're left with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 72

Advancing to step 6:
217 divided by 72 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13383.0
If we take 216 away from 217, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 72, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13383.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 72, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 13383.01
Deduct 72 from 100 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 72 fits into 280 3 times, leaving a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 13383.013
Deduct 216 from 280 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 13383.0138
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
72 can be fit into 640 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 13383.01388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 13383.01388 with a remainder of 6.4e-05.
