77396537 ÷ 999 
We're looking to find how many times 999 goes into 77396537.

On to step 1:
999 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 999

Let's proceed to step 2:
77 divided by 999 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 999

On to step 3:
999 can be fit into 773 0 times, resulting in a remainder of 773.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 773 after subtracting 0 from 773.
Take the next digit (9) from the dividend and append it to 773, then repeat: 7739 / 999

Step 4:
The number 999 fits into 7739 7 times, leaving a remainder of 746.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 6993 from 7739, we get 746.
Bring next digit (6) of the dividend behind the 746 and repeat the process: 7466 / 999

Step 5:
The number 999 fits into 7466 7 times, leaving a remainder of 473.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 6993 from 7466 leaves us with 473.
Bring next digit (5) of the dividend behind the 473 and repeat the process: 4735 / 999

Advancing to step 6:
4735 divided by 999 is 4 with a remainder of 739.
Put 4 as the next digit of the answer. 
Result so far: 774.0
If we subtract 3996 from 4735, we get 739.
Bring next digit (3) of the dividend behind the 739 and repeat the process: 7393 / 999

Advancing to step 7:
If we divide 7393 by 999, we get 7 and a remainder of 400.
The next digit of our result is 7. 
Result so far: 7747.0
If we subtract 6993 from 7393, we get 400.
Grab the next digit (7) from the dividend, add it to 400, then carry on: 4007 / 999

Moving on to step 8:
4007 divided by 999 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 77474.0
The remainder is 11 after subtracting 3996 from 4007.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 999 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 77474.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
If we divide 1100 by 999, we get 1 and a remainder of 101.
The next digit of our result is 1. 
Result so far: 77474.01
If we take 999 away from 1100, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 11:
The number 999 fits into 1010 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 77474.011
The remainder is 11 after subtracting 999 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 77474.011 with a remainder of 0.0011.
