91386977 divided by 999 
Let's see how many times 999 fits into 91386977.

Advancing to step 1:
When dividing 9 by 999, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 999

Going ahead to step 2:
91 divided by 999 is 0 with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 999

On to step 3:
913 divided by 999 is 0 with a remainder of 913.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 913 after subtracting 0 from 913.
Grab the next digit (8) from the dividend, add it to 913, then carry on: 9138 / 999

Going ahead to step 4:
9138 divided by 999 is 9 with a remainder of 147.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 8991 from 9138, we get 147.
Fetch the next digit (6) from the dividend, attach it to 147 and continue: 1476 / 999

Let's proceed to step 5:
If we divide 1476 by 999, we get 1 and a remainder of 477.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 999 from 1476 and we're left with 477.
Fetch the next digit (9) from the dividend, attach it to 477 and continue: 4779 / 999

Advancing to step 6:
999 can be fit into 4779 4 times, resulting in a remainder of 783.
Put 4 as the next digit of the answer. 
Result so far: 914.0
Subtracting 3996 from 4779 leaves us with 783.
Take the next digit (7) from the dividend and append it to 783, then repeat: 7837 / 999

Moving on to step 7:
The number 999 fits into 7837 7 times, leaving a remainder of 844.
Record the quotient 7 as the next digit in the result. 
Result so far: 9147.0
Subtracting 6993 from 7837 leaves us with 844.
Take the next digit (7) from the dividend and append it to 844, then repeat: 8447 / 999

Going ahead to step 8:
If we divide 8447 by 999, we get 8 and a remainder of 455.
Record the quotient 8 as the next digit in the result. 
Result so far: 91478.0
The remainder is 455 after subtracting 7992 from 8447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 9:
When dividing 4550 by 999, we get 4 with a remainder of 554.
The next digit of our result is 4. 
Result so far: 91478.4
Deduct 3996 from 4550 and we're left with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 10:
999 goes into 5540 5 times with a remainder of 545.
Record the quotient 5 as the next digit in the result. 
Result so far: 91478.45
Subtracting 4995 from 5540 leaves us with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 11:
999 goes into 5450 5 times with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 91478.455
Deduct 4995 from 5450 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

After the division, we end up with 91478.455 and a remainder of 0.0455.
