61384488 ÷ 648 
We're looking to find how many times 648 goes into 61384488.

On to step 1:
If we divide 6 by 648, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 648

Going ahead to step 2:
648 goes into 61 0 times with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 648

Step 3:
When dividing 613 by 648, we get 0 with a remainder of 613.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 613 and we're left with 613.
Grab the next digit (8) from the dividend, add it to 613, then carry on: 6138 / 648

Moving on to step 4:
6138 divided by 648 is 9 with a remainder of 306.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 306 after subtracting 5832 from 6138.
Grab the next digit (4) from the dividend, add it to 306, then carry on: 3064 / 648

Step 5:
648 can be fit into 3064 4 times, resulting in a remainder of 472.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtract 2592 from 3064 to get 472.
Append the next digit (4) from the dividend to 472 and continue with: 4724 / 648

Step 6:
If we divide 4724 by 648, we get 7 and a remainder of 188.
Record the quotient 7 as the next digit in the result. 
Result so far: 947.0
Deduct 4536 from 4724 and we're left with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 648

Moving on to step 7:
The number 648 fits into 1888 2 times, leaving a remainder of 592.
The number 2 becomes the next digit in our result. 
Result so far: 9472.0
Subtracting 1296 from 1888 leaves us with 592.
Grab the next digit (8) from the dividend, add it to 592, then carry on: 5928 / 648

Step 8:
648 can be fit into 5928 9 times, resulting in a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 94729.0
The remainder is 96 after subtracting 5832 from 5928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 9:
648 goes into 960 1 times with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 94729.1
Subtract 648 from 960 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 10:
648 can be fit into 3120 4 times, resulting in a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 94729.14
If we take 2592 away from 3120, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 11:
If we divide 5280 by 648, we get 8 and a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 94729.148
If we take 5184 away from 5280, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
648 goes into 960 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 94729.1481
Deduct 648 from 960 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 13:
648 goes into 3120 4 times with a remainder of 528.
The next digit of our result is 4. 
Result so far: 94729.14814
If we subtract 2592 from 3120, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 14:
5280 divided by 648 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 94729.148148
Deduct 5184 from 5280 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
648 goes into 960 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 94729.1481481
If we take 648 away from 960, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 16:
When dividing 3120 by 648, we get 4 with a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 94729.14814814
Subtracting 2592 from 3120 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final outcome is 94729.14814814, with a leftover of 5.28e-07.
