Let's divide 38981057 by 999
We want to figure out the number of times 38981057 can be divided by 999.

Advancing to step 1:
999 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 999

On to step 2:
999 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 999

Going ahead to step 3:
999 goes into 389 0 times with a remainder of 389.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 389 after subtracting 0 from 389.
Take the next digit (8) from the dividend and append it to 389, then repeat: 3898 / 999

Going ahead to step 4:
If we divide 3898 by 999, we get 3 and a remainder of 901.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2997 from 3898 leaves us with 901.
Take the next digit (1) from the dividend and append it to 901, then repeat: 9011 / 999

Moving on to step 5:
999 can be fit into 9011 9 times, resulting in a remainder of 20.
The next digit of our result is 9. 
Result so far: 39.0
Deduct 8991 from 9011 and we're left with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 999

Going ahead to step 6:
When dividing 200 by 999, we get 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 390.0
Subtracting 0 from 200 leaves us with 200.
Bring next digit (5) of the dividend behind the 200 and repeat the process: 2005 / 999

Let's proceed to step 7:
If we divide 2005 by 999, we get 2 and a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 3902.0
Subtract 1998 from 2005 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 999

Going ahead to step 8:
When dividing 77 by 999, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 39020.0
Subtracting 0 from 77 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
If we divide 770 by 999, we get 0 and a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 39020.0
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 10:
If we divide 7700 by 999, we get 7 and a remainder of 707.
The next digit of our result is 7. 
Result so far: 39020.07
If we take 6993 away from 7700, we end up with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

On to step 11:
999 goes into 7070 7 times with a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 39020.077
Deduct 6993 from 7070 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 39020.077, with a leftover of 0.0077.
