We look at the division of 45131201 by 112 
The aim is to understand the frequency of 112 in 45131201.

On to step 1:
The number 112 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 112

Going ahead to step 2:
When dividing 45 by 112, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 112

Advancing to step 3:
If we divide 451 by 112, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 3 after subtracting 448 from 451.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 112

Step 4:
When dividing 33 by 112, we get 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 33 leaves us with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 112

Moving on to step 5:
If we divide 331 by 112, we get 2 and a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtract 224 from 331 to get 107.
Append the next digit (2) from the dividend to 107 and continue with: 1072 / 112

Going ahead to step 6:
112 can be fit into 1072 9 times, resulting in a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 4029.0
If we subtract 1008 from 1072, we get 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 112

Step 7:
If we divide 640 by 112, we get 5 and a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 40295.0
Deduct 560 from 640 and we're left with 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 112

Going ahead to step 8:
If we divide 801 by 112, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 402957.0
If we subtract 784 from 801, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
112 goes into 170 1 times with a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 402957.1
Deduct 112 from 170 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
580 divided by 112 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 402957.15
Subtracting 560 from 580 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 112 is 1 with a remainder of 88.
The next digit of our result is 1. 
Result so far: 402957.151
Subtracting 112 from 200 leaves us 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:
If we divide 880 by 112, we get 7 and a remainder of 96.
The next digit of our result is 7. 
Result so far: 402957.1517
If we subtract 784 from 880, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
960 divided by 112 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 402957.15178
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 14:
112 goes into 640 5 times with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 402957.151785
The remainder is 80 after subtracting 560 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
When dividing 800 by 112, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 402957.1517857
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.

Let's proceed to step 16:
112 can be fit into 160 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 402957.15178571
If we subtract 112 from 160, we get 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 402957.15178571, and the remainder is 4.8e-08.
