64645130 divided by 647 
We want to figure out the number of times 64645130 can be divided by 647.

On to step 1:
When dividing 6 by 647, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 647

Going ahead to step 2:
The number 647 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 647

Let's proceed to step 3:
647 can be fit into 646 0 times, resulting in a remainder of 646.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 646 and we're left with 646.
Append the next digit (4) from the dividend to 646 and continue with: 6464 / 647

Advancing to step 4:
When dividing 6464 by 647, we get 9 with a remainder of 641.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 5823 from 6464, we get 641.
Grab the next digit (5) from the dividend, add it to 641, then carry on: 6415 / 647

Going ahead to step 5:
647 goes into 6415 9 times with a remainder of 592.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 5823 away from 6415, we end up with 592.
Grab the next digit (1) from the dividend, add it to 592, then carry on: 5921 / 647

Let's proceed to step 6:
5921 divided by 647 is 9 with a remainder of 98.
The next digit of our result is 9. 
Result so far: 999.0
Deduct 5823 from 5921 and we're left with 98.
Take the next digit (3) from the dividend and append it to 98, then repeat: 983 / 647

Moving on to step 7:
647 can be fit into 983 1 times, resulting in a remainder of 336.
Put 1 as the next digit of the answer. 
Result so far: 9991.0
Subtracting 647 from 983 leaves us with 336.
Fetch the next digit (0) from the dividend, attach it to 336 and continue: 3360 / 647

Going ahead to step 8:
The number 647 fits into 3360 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 99915.0
The remainder is 125 after subtracting 3235 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
647 goes into 1250 1 times with a remainder of 603.
Write down 1 as next digit of the result. 
Result so far: 99915.1
The remainder is 603 after subtracting 647 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 10:
When dividing 6030 by 647, we get 9 with a remainder of 207.
Use 9 as the next digit of our solution. 
Result so far: 99915.19
Subtracting 5823 from 6030 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 11:
The number 647 fits into 2070 3 times, leaving a remainder of 129.
The next digit of our result is 3. 
Result so far: 99915.193
If we take 1941 away from 2070, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 12:
647 goes into 1290 1 times with a remainder of 643.
Use 1 as the next digit of our solution. 
Result so far: 99915.1931
Subtracting 647 from 1290 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 13:
The number 647 fits into 6430 9 times, leaving a remainder of 607.
The number 9 becomes the next digit in our result. 
Result so far: 99915.19319
The remainder is 607 after subtracting 5823 from 6430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 14:
647 goes into 6070 9 times with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 99915.193199
If we subtract 5823 from 6070, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

After the division, we end up with 99915.193199 and a remainder of 2.47e-05.
