We look at the division of 64215432 by 249 
We're looking to find how many times 249 goes into 64215432.

Going ahead to step 1:
The number 249 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 249

Moving on to step 2:
If we divide 64 by 249, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 249

Going ahead to step 3:
If we divide 642 by 249, we get 2 and a remainder of 144.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 498 from 642 to get 144.
Append the next digit (1) from the dividend to 144 and continue with: 1441 / 249

Moving on to step 4:
If we divide 1441 by 249, we get 5 and a remainder of 196.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 1245 away from 1441, we end up with 196.
Fetch the next digit (5) from the dividend, attach it to 196 and continue: 1965 / 249

Going ahead to step 5:
1965 divided by 249 is 7 with a remainder of 222.
Put 7 as the next digit of the answer. 
Result so far: 257.0
If we subtract 1743 from 1965, we get 222.
Fetch the next digit (4) from the dividend, attach it to 222 and continue: 2224 / 249

Step 6:
249 can be fit into 2224 8 times, resulting in a remainder of 232.
The number 8 becomes the next digit in our result. 
Result so far: 2578.0
If we subtract 1992 from 2224, we get 232.
Fetch the next digit (3) from the dividend, attach it to 232 and continue: 2323 / 249

Moving on to step 7:
If we divide 2323 by 249, we get 9 and a remainder of 82.
Use 9 as the next digit of our solution. 
Result so far: 25789.0
If we subtract 2241 from 2323, we get 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 249

Moving on to step 8:
If we divide 822 by 249, we get 3 and a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 257893.0
The remainder is 75 after subtracting 747 from 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
750 divided by 249 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 257893.3
The remainder is 3 after subtracting 747 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
249 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 257893.3
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
If we divide 300 by 249, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 257893.301
Deduct 249 from 300 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
When dividing 510 by 249, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 257893.3012
Subtract 498 from 510 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
120 divided by 249 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 257893.3012
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
249 goes into 1200 4 times with a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 257893.301204
If we subtract 996 from 1200, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
249 can be fit into 2040 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 257893.3012048
Subtracting 1992 from 2040 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
When dividing 480 by 249, we get 1 with a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 257893.30120481
If we subtract 249 from 480, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The quotient of the division is 257893.30120481, and the remainder is 2.31e-07.
