40686956 ÷ 648 
We're looking to find how many times 648 goes into 40686956.

On to step 1:
648 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 648

Going ahead to step 2:
If we divide 40 by 648, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 648

Going ahead to step 3:
When dividing 406 by 648, we get 0 with a remainder of 406.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 406, we end up with 406.
Take the next digit (8) from the dividend and append it to 406, then repeat: 4068 / 648

Going ahead to step 4:
If we divide 4068 by 648, we get 6 and a remainder of 180.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 3888 away from 4068, we end up with 180.
Take the next digit (6) from the dividend and append it to 180, then repeat: 1806 / 648

Step 5:
648 can be fit into 1806 2 times, resulting in a remainder of 510.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 1296 away from 1806, we end up with 510.
Bring next digit (9) of the dividend behind the 510 and repeat the process: 5109 / 648

Let's proceed to step 6:
5109 divided by 648 is 7 with a remainder of 573.
The next digit of our result is 7. 
Result so far: 627.0
If we subtract 4536 from 5109, we get 573.
Grab the next digit (5) from the dividend, add it to 573, then carry on: 5735 / 648

On to step 7:
648 goes into 5735 8 times with a remainder of 551.
Use 8 as the next digit of our solution. 
Result so far: 6278.0
Subtracting 5184 from 5735 leaves us with 551.
Grab the next digit (6) from the dividend, add it to 551, then carry on: 5516 / 648

Let's proceed to step 8:
If we divide 5516 by 648, we get 8 and a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 62788.0
If we take 5184 away from 5516, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 9:
3320 divided by 648 is 5 with a remainder of 80.
The next digit of our result is 5. 
Result so far: 62788.5
Deduct 3240 from 3320 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
800 divided by 648 is 1 with a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 62788.51
If we subtract 648 from 800, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 11:
648 goes into 1520 2 times with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 62788.512
Subtract 1296 from 1520 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
If we divide 2240 by 648, we get 3 and a remainder of 296.
Use 3 as the next digit of our solution. 
Result so far: 62788.5123
Deduct 1944 from 2240 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 13:
When dividing 2960 by 648, we get 4 with a remainder of 368.
The next digit of our result is 4. 
Result so far: 62788.51234
Subtracting 2592 from 2960 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 14:
3680 divided by 648 is 5 with a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 62788.512345
Deduct 3240 from 3680 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 15:
648 goes into 4400 6 times with a remainder of 512.
Record the quotient 6 as the next digit in the result. 
Result so far: 62788.5123456
Subtracting 3888 from 4400 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 16:
When dividing 5120 by 648, we get 7 with a remainder of 584.
The number 7 becomes the next digit in our result. 
Result so far: 62788.51234567
Subtract 4536 from 5120 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

In conclusion, the division gives 62788.51234567 with a balance of 5.84e-07.
