72218014 divided by 112 
The aim is to understand the frequency of 112 in 72218014.

On to step 1:
If we divide 7 by 112, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 112

Going ahead to step 2:
The number 112 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 112

Moving on to step 3:
112 goes into 722 6 times with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 672 from 722 and we're left with 50.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 112

Going ahead to step 4:
112 goes into 501 4 times with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 448 away from 501, we end up with 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 112

Going ahead to step 5:
538 divided by 112 is 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 644.0
Subtracting 448 from 538 leaves us with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 112

On to step 6:
900 divided by 112 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 6448.0
Subtract 896 from 900 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 112

Moving on to step 7:
41 divided by 112 is 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 64480.0
If we take 0 away from 41, we end up with 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 112

On to step 8:
If we divide 414 by 112, we get 3 and a remainder of 78.
Put 3 as the next digit of the answer. 
Result so far: 644803.0
If we take 336 away from 414, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
When dividing 780 by 112, we get 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 644803.6
If we subtract 672 from 780, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
1080 divided by 112 is 9 with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 644803.69
Subtracting 1008 from 1080 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
112 goes into 720 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 644803.696
Subtracting 672 from 720 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 112 fits into 480 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 644803.6964
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
If we divide 320 by 112, we get 2 and a remainder of 96.
The next digit of our result is 2. 
Result so far: 644803.69642
Subtracting 224 from 320 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 14:
960 divided by 112 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 644803.696428
The remainder is 64 after subtracting 896 from 960.
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 15:
The number 112 fits into 640 5 times, leaving a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 644803.6964285
Subtracting 560 from 640 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
112 can be fit into 800 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 644803.69642857
Subtract 784 from 800 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.

The final outcome is 644803.69642857, with a leftover of 1.6e-08.
