We're looking to find how many times 999 goes into 84451043.

Advancing to step 1:
999 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 999

Advancing to step 2:
999 can be fit into 84 0 times, resulting in a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 999

Moving on to step 3:
844 divided by 999 is 0 with a remainder of 844.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 844 after subtracting 0 from 844.
Include the next digit (5) from the dividend after 844, then repeat: 8445 / 999

Moving on to step 4:
If we divide 8445 by 999, we get 8 and a remainder of 453.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7992 from 8445 to get 453.
Grab the next digit (1) from the dividend, add it to 453, then carry on: 4531 / 999

On to step 5:
The number 999 fits into 4531 4 times, leaving a remainder of 535.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Deduct 3996 from 4531 and we're left with 535.
Take the next digit (0) from the dividend and append it to 535, then repeat: 5350 / 999

Advancing to step 6:
The number 999 fits into 5350 5 times, leaving a remainder of 355.
Record the quotient 5 as the next digit in the result. 
Result so far: 845.0
Subtract 4995 from 5350 to get 355.
Take the next digit (4) from the dividend and append it to 355, then repeat: 3554 / 999

Moving on to step 7:
When dividing 3554 by 999, we get 3 with a remainder of 557.
The number 3 becomes the next digit in our result. 
Result so far: 8453.0
Deduct 2997 from 3554 and we're left with 557.
Append the next digit (3) from the dividend to 557 and continue with: 5573 / 999

On to step 8:
When dividing 5573 by 999, we get 5 with a remainder of 578.
Use 5 as the next digit of our solution. 
Result so far: 84535.0
If we take 4995 away from 5573, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 9:
999 can be fit into 5780 5 times, resulting in a remainder of 785.
Record the quotient 5 as the next digit in the result. 
Result so far: 84535.5
Deduct 4995 from 5780 and we're left with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Moving on to step 10:
When dividing 7850 by 999, we get 7 with a remainder of 857.
Record the quotient 7 as the next digit in the result. 
Result so far: 84535.57
Deduct 6993 from 7850 and we're left with 857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

Let's proceed to step 11:
999 can be fit into 8570 8 times, resulting in a remainder of 578.
The next digit of our result is 8. 
Result so far: 84535.578
Subtract 7992 from 8570 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 12:
The number 999 fits into 5780 5 times, leaving a remainder of 785.
The next digit of our result is 5. 
Result so far: 84535.5785
The remainder is 785 after subtracting 4995 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Going ahead to step 13:
999 can be fit into 7850 7 times, resulting in a remainder of 857.
Record the quotient 7 as the next digit in the result. 
Result so far: 84535.57857
Subtracting 6993 from 7850 leaves us with 857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

On to step 14:
8570 divided by 999 is 8 with a remainder of 578.
Use 8 as the next digit of our solution. 
Result so far: 84535.578578
If we take 7992 away from 8570, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 15:
When dividing 5780 by 999, we get 5 with a remainder of 785.
The next digit of our result is 5. 
Result so far: 84535.5785785
Subtracting 4995 from 5780 leaves us with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

On to step 16:
7850 divided by 999 is 7 with a remainder of 857.
Record the quotient 7 as the next digit in the result. 
Result so far: 84535.57857857
Deduct 6993 from 7850 and we're left with 857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

Our division results in 84535.57857857 with a remaining 8.57e-07.
