8007445 ÷ 578 
We want to figure out the number of times 8007445 can be divided by 578.

Moving on to step 1:
8 divided by 578 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 578

Going ahead to step 2:
When dividing 80 by 578, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 578

Moving on to step 3:
If we divide 800 by 578, we get 1 and a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 578 from 800, we get 222.
Bring next digit (7) of the dividend behind the 222 and repeat the process: 2227 / 578

Let's proceed to step 4:
If we divide 2227 by 578, we get 3 and a remainder of 493.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1734 from 2227 and we're left with 493.
Fetch the next digit (4) from the dividend, attach it to 493 and continue: 4934 / 578

Advancing to step 5:
If we divide 4934 by 578, we get 8 and a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we take 4624 away from 4934, we end up with 310.
Grab the next digit (4) from the dividend, add it to 310, then carry on: 3104 / 578

Step 6:
3104 divided by 578 is 5 with a remainder of 214.
Use 5 as the next digit of our solution. 
Result so far: 1385.0
If we take 2890 away from 3104, we end up with 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 578

Going ahead to step 7:
578 can be fit into 2145 3 times, resulting in a remainder of 411.
The next digit of our result is 3. 
Result so far: 13853.0
If we subtract 1734 from 2145, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 8:
When dividing 4110 by 578, we get 7 with a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 13853.7
Deduct 4046 from 4110 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
578 goes into 640 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 13853.71
Subtract 578 from 640 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
The number 578 fits into 620 1 times, leaving a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 13853.711
Subtract 578 from 620 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 13853.711 with a remainder of 0.0042.
