We look at the division of 90665890 by 112 
The aim is to understand the frequency of 112 in 90665890.

Moving on to step 1:
112 goes into 9 0 times with 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 (0) from the dividend, attach it to 9 and continue: 90 / 112

Going ahead to step 2:
112 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 112

Advancing to step 3:
112 can be fit into 906 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 896 from 906 and we're left with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 112

Advancing to step 4:
The number 112 fits into 106 0 times, leaving a remainder of 106.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 106 to get 106.
Append the next digit (5) from the dividend to 106 and continue with: 1065 / 112

Moving on to step 5:
1065 divided by 112 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 809.0
Deduct 1008 from 1065 and we're left with 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 112

Let's proceed to step 6:
578 divided by 112 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 8095.0
Deduct 560 from 578 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 112

Let's proceed to step 7:
The number 112 fits into 189 1 times, leaving a remainder of 77.
The next digit of our result is 1. 
Result so far: 80951.0
Subtract 112 from 189 to get 77.
Grab the next digit (0) from the dividend, add it to 77, then carry on: 770 / 112

Advancing to step 8:
If we divide 770 by 112, we get 6 and a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 809516.0
Deduct 672 from 770 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
The number 112 fits into 980 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 809516.8
Deduct 896 from 980 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
840 divided by 112 is 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 809516.87
Subtracting 784 from 840 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
112 can be fit into 560 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 809516.875
If we take 560 away from 560, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 112, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 809516.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
If we divide 0 by 112, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 809516.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 809516.875 with a remainder of 0.0.
