We're dividing 17113860 by 445 
The aim is to understand the frequency of 445 in 17113860.

On to step 1:
The number 445 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 445

Let's proceed to step 2:
When dividing 17 by 445, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 445

On to step 3:
If we divide 171 by 445, we get 0 and a remainder of 171.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 171 leaves us with 171.
Append the next digit (1) from the dividend to 171 and continue with: 1711 / 445

Going ahead to step 4:
If we divide 1711 by 445, we get 3 and a remainder of 376.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1335 from 1711 leaves us with 376.
Append the next digit (3) from the dividend to 376 and continue with: 3763 / 445

On to step 5:
When dividing 3763 by 445, we get 8 with a remainder of 203.
The next digit of our result is 8. 
Result so far: 38.0
If we take 3560 away from 3763, we end up with 203.
Fetch the next digit (8) from the dividend, attach it to 203 and continue: 2038 / 445

Moving on to step 6:
The number 445 fits into 2038 4 times, leaving a remainder of 258.
The next digit of our result is 4. 
Result so far: 384.0
The remainder is 258 after subtracting 1780 from 2038.
Include the next digit (6) from the dividend after 258, then repeat: 2586 / 445

Going ahead to step 7:
2586 divided by 445 is 5 with a remainder of 361.
The number 5 becomes the next digit in our result. 
Result so far: 3845.0
Subtract 2225 from 2586 to get 361.
Take the next digit (0) from the dividend and append it to 361, then repeat: 3610 / 445

On to step 8:
3610 divided by 445 is 8 with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 38458.0
If we subtract 3560 from 3610, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 445 is 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 38458.1
Deduct 445 from 500 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
550 divided by 445 is 1 with a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 38458.11
The remainder is 105 after subtracting 445 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 38458.11, and the remainder is 0.105.
