We divide 70885681 by 445
The aim is to understand the frequency of 445 in 70885681.

On to step 1:
7 divided by 445 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 445

Step 2:
When dividing 70 by 445, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 445

Going ahead to step 3:
708 divided by 445 is 1 with a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 445 from 708 and we're left with 263.
Bring next digit (8) of the dividend behind the 263 and repeat the process: 2638 / 445

Step 4:
When dividing 2638 by 445, we get 5 with a remainder of 413.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2225 from 2638 leaves us with 413.
Append the next digit (5) from the dividend to 413 and continue with: 4135 / 445

Advancing to step 5:
445 can be fit into 4135 9 times, resulting in a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 4005 away from 4135, we end up with 130.
Bring next digit (6) of the dividend behind the 130 and repeat the process: 1306 / 445

Going ahead to step 6:
The number 445 fits into 1306 2 times, leaving a remainder of 416.
Put 2 as the next digit of the answer. 
Result so far: 1592.0
Deduct 890 from 1306 and we're left with 416.
Include the next digit (8) from the dividend after 416, then repeat: 4168 / 445

Step 7:
The number 445 fits into 4168 9 times, leaving a remainder of 163.
Put 9 as the next digit of the answer. 
Result so far: 15929.0
The remainder is 163 after subtracting 4005 from 4168.
Fetch the next digit (1) from the dividend, attach it to 163 and continue: 1631 / 445

Let's proceed to step 8:
445 can be fit into 1631 3 times, resulting in a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 159293.0
Subtract 1335 from 1631 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 9:
445 can be fit into 2960 6 times, resulting in a remainder of 290.
The next digit of our result is 6. 
Result so far: 159293.6
Subtracting 2670 from 2960 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 10:
445 can be fit into 2900 6 times, resulting in a remainder of 230.
Put 6 as the next digit of the answer. 
Result so far: 159293.66
The remainder is 230 after subtracting 2670 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

After the division, we end up with 159293.66 and a remainder of 0.23.
