57973355 divided by 647 
We want to figure out the number of times 57973355 can be divided by 647.

Step 1:
If we divide 5 by 647, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 647

Going ahead to step 2:
647 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 647

Going ahead to step 3:
The number 647 fits into 579 0 times, leaving a remainder of 579.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 579, we end up with 579.
Append the next digit (7) from the dividend to 579 and continue with: 5797 / 647

Step 4:
When dividing 5797 by 647, we get 8 with a remainder of 621.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 5176 from 5797 leaves us with 621.
Take the next digit (3) from the dividend and append it to 621, then repeat: 6213 / 647

Moving on to step 5:
647 goes into 6213 9 times with a remainder of 390.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Subtracting 5823 from 6213 leaves us with 390.
Include the next digit (3) from the dividend after 390, then repeat: 3903 / 647

Advancing to step 6:
If we divide 3903 by 647, we get 6 and a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 896.0
Subtract 3882 from 3903 to get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 647

Going ahead to step 7:
647 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 8960.0
Deduct 0 from 215 and we're left with 215.
Include the next digit (5) from the dividend after 215, then repeat: 2155 / 647

Step 8:
647 can be fit into 2155 3 times, resulting in a remainder of 214.
Write down 3 as next digit of the result. 
Result so far: 89603.0
The remainder is 214 after subtracting 1941 from 2155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 9:
2140 divided by 647 is 3 with a remainder of 199.
The next digit of our result is 3. 
Result so far: 89603.3
The remainder is 199 after subtracting 1941 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 10:
If we divide 1990 by 647, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 89603.33
If we take 1941 away from 1990, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 89603.33 and a remainder of 0.049.
