Let's divide 21319903 by 112
The aim is to understand the frequency of 112 in 21319903.

Going ahead to step 1:
2 divided by 112 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 112

Let's proceed to step 2:
21 divided by 112 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 112

Advancing to step 3:
112 can be fit into 213 1 times, resulting in a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 112 from 213, we get 101.
Append the next digit (1) from the dividend to 101 and continue with: 1011 / 112

Step 4:
When dividing 1011 by 112, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 1008 from 1011 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 112

On to step 5:
112 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 112

Step 6:
399 divided by 112 is 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 1903.0
Deduct 336 from 399 and we're left with 63.
Include the next digit (0) from the dividend after 63, then repeat: 630 / 112

On to step 7:
112 can be fit into 630 5 times, resulting in a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 19035.0
Subtracting 560 from 630 leaves us with 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 112

Step 8:
When dividing 703 by 112, we get 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 190356.0
If we take 672 away from 703, we end up 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.

On to step 9:
When dividing 310 by 112, we get 2 with a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 190356.2
If we take 224 away from 310, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 10:
If we divide 860 by 112, we get 7 and a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 190356.27
The remainder is 76 after subtracting 784 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
760 divided by 112 is 6 with a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 190356.276
If we take 672 away from 760, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
880 divided by 112 is 7 with a remainder of 96.
The next digit of our result is 7. 
Result so far: 190356.2767
The remainder is 96 after subtracting 784 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 13:
If we divide 960 by 112, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 190356.27678
Subtracting 896 from 960 leaves us 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.

Let's proceed to step 14:
The number 112 fits into 640 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 190356.276785
If we subtract 560 from 640, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 15:
112 can be fit into 800 7 times, resulting in a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 190356.2767857
If we take 784 away from 800, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
112 goes into 160 1 times with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 190356.27678571
Subtracting 112 from 160 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.

The quotient of the division is 190356.27678571, and the remainder is 4.8e-08.
