We're dividing 36872643 by 578 
We want to figure out the number of times 36872643 can be divided by 578.

On to step 1:
578 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 578

Moving on to step 2:
36 divided by 578 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 578

Let's proceed to step 3:
578 goes into 368 0 times with a remainder of 368.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 368, we end up with 368.
Fetch the next digit (7) from the dividend, attach it to 368 and continue: 3687 / 578

Moving on to step 4:
3687 divided by 578 is 6 with a remainder of 219.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 219 after subtracting 3468 from 3687.
Grab the next digit (2) from the dividend, add it to 219, then carry on: 2192 / 578

On to step 5:
When dividing 2192 by 578, we get 3 with a remainder of 458.
Write down 3 as next digit of the result. 
Result so far: 63.0
If we subtract 1734 from 2192, we get 458.
Include the next digit (6) from the dividend after 458, then repeat: 4586 / 578

Let's proceed to step 6:
4586 divided by 578 is 7 with a remainder of 540.
Write down 7 as next digit of the result. 
Result so far: 637.0
If we subtract 4046 from 4586, we get 540.
Append the next digit (4) from the dividend to 540 and continue with: 5404 / 578

Step 7:
The number 578 fits into 5404 9 times, leaving a remainder of 202.
The next digit of our result is 9. 
Result so far: 6379.0
Subtracting 5202 from 5404 leaves us with 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 578

On to step 8:
578 can be fit into 2023 3 times, resulting in a remainder of 289.
Use 3 as the next digit of our solution. 
Result so far: 63793.0
Subtracting 1734 from 2023 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 9:
The number 578 fits into 2890 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 63793.5
If we take 2890 away from 2890, 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.

Let's proceed to step 10:
578 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 63793.5
Deduct 0 from 0 and we're left 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 11:
578 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 63793.5
If we take 0 away from 0, 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.

After the division, we end up with 63793.5 and a remainder of 0.0.
