64564753 divided by 257 
Let's see how many times 257 fits into 64564753.

Moving on to step 1:
6 divided by 257 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 257

Moving on to step 2:
257 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (5) from the dividend to 64 and continue with: 645 / 257

Moving on to step 3:
645 divided by 257 is 2 with a remainder of 131.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 514 from 645, we get 131.
Include the next digit (6) from the dividend after 131, then repeat: 1316 / 257

Step 4:
The number 257 fits into 1316 5 times, leaving a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 1285 from 1316 leaves us with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 257

Step 5:
257 goes into 314 1 times with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Subtracting 257 from 314 leaves us with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 257

Moving on to step 6:
The number 257 fits into 577 2 times, leaving a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 2512.0
If we subtract 514 from 577, we get 63.
Include the next digit (5) from the dividend after 63, then repeat: 635 / 257

Going ahead to step 7:
The number 257 fits into 635 2 times, leaving a remainder of 121.
Put 2 as the next digit of the answer. 
Result so far: 25122.0
If we subtract 514 from 635, we get 121.
Grab the next digit (3) from the dividend, add it to 121, then carry on: 1213 / 257

Let's proceed to step 8:
257 can be fit into 1213 4 times, resulting in a remainder of 185.
Put 4 as the next digit of the answer. 
Result so far: 251224.0
Deduct 1028 from 1213 and we're left with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 9:
The number 257 fits into 1850 7 times, leaving a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 251224.7
Subtract 1799 from 1850 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
257 can be fit into 510 1 times, resulting in a remainder of 253.
The next digit of our result is 1. 
Result so far: 251224.71
Subtract 257 from 510 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 11:
257 goes into 2530 9 times with a remainder of 217.
Use 9 as the next digit of our solution. 
Result so far: 251224.719
Deduct 2313 from 2530 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 12:
257 goes into 2170 8 times with a remainder of 114.
The next digit of our result is 8. 
Result so far: 251224.7198
If we subtract 2056 from 2170, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 13:
257 can be fit into 1140 4 times, resulting in a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 251224.71984
Subtract 1028 from 1140 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
When dividing 1120 by 257, we get 4 with a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 251224.719844
Deduct 1028 from 1120 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 251224.719844, with a leftover of 9.2e-06.
