We divide 64564209 by 391
We're looking to find how many times 391 goes into 64564209.

Moving on to step 1:
When dividing 6 by 391, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 391

Advancing to step 2:
64 divided by 391 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 391

Step 3:
The number 391 fits into 645 1 times, leaving a remainder of 254.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 391 from 645 leaves us with 254.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 391

Let's proceed to step 4:
391 can be fit into 2546 6 times, resulting in a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 200 after subtracting 2346 from 2546.
Grab the next digit (4) from the dividend, add it to 200, then carry on: 2004 / 391

Step 5:
If we divide 2004 by 391, we get 5 and a remainder of 49.
Put 5 as the next digit of the answer. 
Result so far: 165.0
Subtract 1955 from 2004 to get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 391

Moving on to step 6:
391 can be fit into 492 1 times, resulting in a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 1651.0
If we subtract 391 from 492, we get 101.
Take the next digit (0) from the dividend and append it to 101, then repeat: 1010 / 391

Advancing to step 7:
391 goes into 1010 2 times with a remainder of 228.
The next digit of our result is 2. 
Result so far: 16512.0
Subtracting 782 from 1010 leaves us with 228.
Bring next digit (9) of the dividend behind the 228 and repeat the process: 2289 / 391

Let's proceed to step 8:
2289 divided by 391 is 5 with a remainder of 334.
Use 5 as the next digit of our solution. 
Result so far: 165125.0
The remainder is 334 after subtracting 1955 from 2289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 9:
391 goes into 3340 8 times with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 165125.8
If we take 3128 away from 3340, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
391 can be fit into 2120 5 times, resulting in a remainder of 165.
The next digit of our result is 5. 
Result so far: 165125.85
Subtract 1955 from 2120 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
1650 divided by 391 is 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 165125.854
Subtracting 1564 from 1650 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
860 divided by 391 is 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 165125.8542
The remainder is 78 after subtracting 782 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
391 goes into 780 1 times with a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 165125.85421
If we take 391 away from 780, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 14:
3890 divided by 391 is 9 with a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 165125.854219
If we subtract 3519 from 3890, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Step 15:
If we divide 3710 by 391, we get 9 and a remainder of 191.
Use 9 as the next digit of our solution. 
Result so far: 165125.8542199
If we subtract 3519 from 3710, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The final outcome is 165125.8542199, with a leftover of 1.91e-06.
