We look at the division of 49398276 by 648 
Our goal is to divide 49398276 by 648.

Let's proceed to step 1:
648 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 648

Advancing to step 2:
The number 648 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 648

Moving on to step 3:
When dividing 493 by 648, we get 0 with a remainder of 493.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 493, we end up with 493.
Append the next digit (9) from the dividend to 493 and continue with: 4939 / 648

Step 4:
If we divide 4939 by 648, we get 7 and a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 403 after subtracting 4536 from 4939.
Grab the next digit (8) from the dividend, add it to 403, then carry on: 4038 / 648

Going ahead to step 5:
648 goes into 4038 6 times with a remainder of 150.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtract 3888 from 4038 to get 150.
Grab the next digit (2) from the dividend, add it to 150, then carry on: 1502 / 648

Moving on to step 6:
The number 648 fits into 1502 2 times, leaving a remainder of 206.
The next digit of our result is 2. 
Result so far: 762.0
Deduct 1296 from 1502 and we're left with 206.
Bring next digit (7) of the dividend behind the 206 and repeat the process: 2067 / 648

Step 7:
If we divide 2067 by 648, we get 3 and a remainder of 123.
The next digit of our result is 3. 
Result so far: 7623.0
Deduct 1944 from 2067 and we're left with 123.
Fetch the next digit (6) from the dividend, attach it to 123 and continue: 1236 / 648

Step 8:
1236 divided by 648 is 1 with a remainder of 588.
Record the quotient 1 as the next digit in the result. 
Result so far: 76231.0
Subtracting 648 from 1236 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 9:
When dividing 5880 by 648, we get 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 76231.9
If we take 5832 away from 5880, we end up 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.

Advancing to step 10:
The number 648 fits into 480 0 times, leaving a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 76231.9
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 11:
648 can be fit into 4800 7 times, resulting in a remainder of 264.
The next digit of our result is 7. 
Result so far: 76231.907
Deduct 4536 from 4800 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
2640 divided by 648 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 76231.9074
Deduct 2592 from 2640 and we're left 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.

Moving on to step 13:
648 can be fit into 480 0 times, resulting in a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 76231.9074
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
If we divide 4800 by 648, we get 7 and a remainder of 264.
The next digit of our result is 7. 
Result so far: 76231.907407
The remainder is 264 after subtracting 4536 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 15:
The number 648 fits into 2640 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 76231.9074074
The remainder is 48 after subtracting 2592 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 16:
The number 648 fits into 480 0 times, leaving a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 76231.9074074
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 76231.9074074, with a leftover of 4.8e-07.
