39491418 ÷ 488 
We want to figure out the number of times 39491418 can be divided by 488.

Going ahead to step 1:
When dividing 3 by 488, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 488

Let's proceed to step 2:
The number 488 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 488

On to step 3:
The number 488 fits into 394 0 times, leaving a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 394, we end up with 394.
Bring next digit (9) of the dividend behind the 394 and repeat the process: 3949 / 488

On to step 4:
488 goes into 3949 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 3904 from 3949, we get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 488

Advancing to step 5:
The number 488 fits into 451 0 times, leaving a remainder of 451.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 451 leaves us with 451.
Take the next digit (4) from the dividend and append it to 451, then repeat: 4514 / 488

Moving on to step 6:
488 can be fit into 4514 9 times, resulting in a remainder of 122.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
If we subtract 4392 from 4514, we get 122.
Fetch the next digit (1) from the dividend, attach it to 122 and continue: 1221 / 488

Going ahead to step 7:
488 goes into 1221 2 times with a remainder of 245.
Record the quotient 2 as the next digit in the result. 
Result so far: 8092.0
Deduct 976 from 1221 and we're left with 245.
Take the next digit (8) from the dividend and append it to 245, then repeat: 2458 / 488

Moving on to step 8:
488 goes into 2458 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 80925.0
The remainder is 18 after subtracting 2440 from 2458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
488 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 80925.0
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
If we divide 1800 by 488, we get 3 and a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 80925.03
If we take 1464 away from 1800, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 11:
When dividing 3360 by 488, we get 6 with a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 80925.036
Deduct 2928 from 3360 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
488 can be fit into 4320 8 times, resulting in a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 80925.0368
If we subtract 3904 from 4320, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 13:
4160 divided by 488 is 8 with a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 80925.03688
Deduct 3904 from 4160 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 80925.03688, with a leftover of 0.000256.
