We're dividing 71543410 by 112 
The aim is to understand the frequency of 112 in 71543410.

Let's proceed to step 1:
7 divided by 112 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 112

Let's proceed to step 2:
When dividing 71 by 112, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 112

Moving on to step 3:
112 can be fit into 715 6 times, resulting in a remainder of 43.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 672 from 715, we get 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 112

Let's proceed to step 4:
112 goes into 434 3 times with a remainder of 98.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtracting 336 from 434 leaves us with 98.
Grab the next digit (3) from the dividend, add it to 98, then carry on: 983 / 112

On to step 5:
If we divide 983 by 112, we get 8 and a remainder of 87.
Use 8 as the next digit of our solution. 
Result so far: 638.0
If we subtract 896 from 983, we get 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 112

Moving on to step 6:
112 can be fit into 874 7 times, resulting in a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 6387.0
If we subtract 784 from 874, we get 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 112

On to step 7:
If we divide 901 by 112, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 63878.0
Subtracting 896 from 901 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 112

Going ahead to step 8:
When dividing 50 by 112, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 638780.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
500 divided by 112 is 4 with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 638780.4
The remainder is 52 after subtracting 448 from 500.
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 10:
112 goes into 520 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 638780.44
Deduct 448 from 520 and we're left 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.

After the division, we end up with 638780.44 and a remainder of 0.072.
