64352419 ÷ 257 
We want to divide 64352419 by 257.

Going ahead to step 1:
257 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 257

Going ahead to step 2:
When dividing 64 by 257, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 257

On to step 3:
When dividing 643 by 257, we get 2 with a remainder of 129.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 514 from 643 leaves us with 129.
Fetch the next digit (5) from the dividend, attach it to 129 and continue: 1295 / 257

Going ahead to step 4:
1295 divided by 257 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 25.0
If we take 1285 away from 1295, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 257

Let's proceed to step 5:
If we divide 102 by 257, we get 0 and a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 102, we end up with 102.
Grab the next digit (4) from the dividend, add it to 102, then carry on: 1024 / 257

Advancing to step 6:
The number 257 fits into 1024 3 times, leaving a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 2503.0
If we take 771 away from 1024, we end up with 253.
Bring next digit (1) of the dividend behind the 253 and repeat the process: 2531 / 257

Advancing to step 7:
257 can be fit into 2531 9 times, resulting in a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 25039.0
Subtracting 2313 from 2531 leaves us with 218.
Include the next digit (9) from the dividend after 218, then repeat: 2189 / 257

Moving on to step 8:
If we divide 2189 by 257, we get 8 and a remainder of 133.
Use 8 as the next digit of our solution. 
Result so far: 250398.0
Deduct 2056 from 2189 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 9:
1330 divided by 257 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 250398.5
If we subtract 1285 from 1330, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 257, we get 1 with a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 250398.51
The remainder is 193 after subtracting 257 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 11:
257 goes into 1930 7 times with a remainder of 131.
The next digit of our result is 7. 
Result so far: 250398.517
Deduct 1799 from 1930 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 12:
257 can be fit into 1310 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 250398.5175
Subtract 1285 from 1310 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
The number 257 fits into 250 0 times, leaving a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 250398.5175
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 14:
When dividing 2500 by 257, we get 9 with a remainder of 187.
Put 9 as the next digit of the answer. 
Result so far: 250398.517509
The remainder is 187 after subtracting 2313 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 15:
257 can be fit into 1870 7 times, resulting in a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 250398.5175097
If we take 1799 away from 1870, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 16:
257 can be fit into 710 2 times, resulting in a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 250398.51750972
If we subtract 514 from 710, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Our division results in 250398.51750972 with a remaining 1.96e-07.
