We look at the division of 38902498 by 648 
We want to divide 38902498 by 648.

Let's proceed to step 1:
If we divide 3 by 648, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 648

Moving on to step 2:
When dividing 38 by 648, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 648

Moving on to step 3:
648 goes into 389 0 times with a remainder of 389.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 389 and we're left with 389.
Fetch the next digit (0) from the dividend, attach it to 389 and continue: 3890 / 648

Going ahead to step 4:
When dividing 3890 by 648, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 3888 from 3890 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 648

Let's proceed to step 5:
22 divided by 648 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 648

Moving on to step 6:
If we divide 224 by 648, we get 0 and a remainder of 224.
Put 0 as the next digit of the answer. 
Result so far: 600.0
Subtracting 0 from 224 leaves us with 224.
Include the next digit (9) from the dividend after 224, then repeat: 2249 / 648

Moving on to step 7:
The number 648 fits into 2249 3 times, leaving a remainder of 305.
Put 3 as the next digit of the answer. 
Result so far: 6003.0
If we take 1944 away from 2249, we end up with 305.
Fetch the next digit (8) from the dividend, attach it to 305 and continue: 3058 / 648

On to step 8:
When dividing 3058 by 648, we get 4 with a remainder of 466.
Put 4 as the next digit of the answer. 
Result so far: 60034.0
Subtract 2592 from 3058 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 9:
648 can be fit into 4660 7 times, resulting in a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 60034.7
Deduct 4536 from 4660 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
648 goes into 1240 1 times with a remainder of 592.
Write down 1 as next digit of the result. 
Result so far: 60034.71
Subtracting 648 from 1240 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 11:
648 can be fit into 5920 9 times, resulting in a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 60034.719
If we subtract 5832 from 5920, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
The number 648 fits into 880 1 times, leaving a remainder of 232.
The next digit of our result is 1. 
Result so far: 60034.7191
Subtracting 648 from 880 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 13:
2320 divided by 648 is 3 with a remainder of 376.
Record the quotient 3 as the next digit in the result. 
Result so far: 60034.71913
Subtract 1944 from 2320 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 14:
648 goes into 3760 5 times with a remainder of 520.
Write down 5 as next digit of the result. 
Result so far: 60034.719135
Deduct 3240 from 3760 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Let's proceed to step 15:
The number 648 fits into 5200 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 60034.7191358
Subtracting 5184 from 5200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 16:
The number 648 fits into 160 0 times, leaving a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 60034.7191358
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 60034.7191358, with a leftover of 1.6e-07.
