39854013 divided by 872 
We want to divide 39854013 by 872.

Step 1:
When dividing 3 by 872, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 872

On to step 2:
39 divided by 872 is 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 872

Moving on to step 3:
872 goes into 398 0 times with a remainder of 398.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 398 leaves us with 398.
Fetch the next digit (5) from the dividend, attach it to 398 and continue: 3985 / 872

On to step 4:
3985 divided by 872 is 4 with a remainder of 497.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 3488 from 3985, we get 497.
Take the next digit (4) from the dividend and append it to 497, then repeat: 4974 / 872

Moving on to step 5:
872 goes into 4974 5 times with a remainder of 614.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 4360 from 4974 leaves us with 614.
Bring next digit (0) of the dividend behind the 614 and repeat the process: 6140 / 872

Step 6:
872 can be fit into 6140 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
If we take 6104 away from 6140, we end up with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 872

Advancing to step 7:
361 divided by 872 is 0 with a remainder of 361.
The next digit of our result is 0. 
Result so far: 4570.0
Deduct 0 from 361 and we're left with 361.
Take the next digit (3) from the dividend and append it to 361, then repeat: 3613 / 872

Let's proceed to step 8:
872 goes into 3613 4 times with a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 45704.0
If we subtract 3488 from 3613, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 9:
872 can be fit into 1250 1 times, resulting in a remainder of 378.
Put 1 as the next digit of the answer. 
Result so far: 45704.1
Subtracting 872 from 1250 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 10:
872 goes into 3780 4 times with a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 45704.14
If we subtract 3488 from 3780, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 11:
872 can be fit into 2920 3 times, resulting in a remainder of 304.
The number 3 becomes the next digit in our result. 
Result so far: 45704.143
If we take 2616 away from 2920, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
3040 divided by 872 is 3 with a remainder of 424.
Record the quotient 3 as the next digit in the result. 
Result so far: 45704.1433
Subtract 2616 from 3040 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final outcome is 45704.1433, with a leftover of 0.00424.
