We're dividing 15558191 by 445 
We want to figure out the number of times 15558191 can be divided by 445.

Let's proceed to step 1:
445 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 445

Moving on to step 2:
If we divide 15 by 445, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 445

On to step 3:
155 divided by 445 is 0 with a remainder of 155.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Include the next digit (5) from the dividend after 155, then repeat: 1555 / 445

Advancing to step 4:
445 can be fit into 1555 3 times, resulting in a remainder of 220.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 220 after subtracting 1335 from 1555.
Include the next digit (8) from the dividend after 220, then repeat: 2208 / 445

On to step 5:
If we divide 2208 by 445, we get 4 and a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 1780 from 2208 to get 428.
Grab the next digit (1) from the dividend, add it to 428, then carry on: 4281 / 445

Moving on to step 6:
The number 445 fits into 4281 9 times, leaving a remainder of 276.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
If we subtract 4005 from 4281, we get 276.
Take the next digit (9) from the dividend and append it to 276, then repeat: 2769 / 445

Going ahead to step 7:
If we divide 2769 by 445, we get 6 and a remainder of 99.
Use 6 as the next digit of our solution. 
Result so far: 3496.0
If we take 2670 away from 2769, we end up with 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 445

Moving on to step 8:
445 can be fit into 991 2 times, resulting in a remainder of 101.
The number 2 becomes the next digit in our result. 
Result so far: 34962.0
The remainder is 101 after subtracting 890 from 991.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
445 goes into 1010 2 times with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 34962.2
If we subtract 890 from 1010, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
If we divide 1200 by 445, we get 2 and a remainder of 310.
Use 2 as the next digit of our solution. 
Result so far: 34962.22
The remainder is 310 after subtracting 890 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final result is 34962.22 with a remainder of 0.31.
