85784023 ÷ 173 
We want to divide 85784023 by 173.

Step 1:
If we divide 8 by 173, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 173

Let's proceed to step 2:
85 divided by 173 is 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 173

On to step 3:
173 can be fit into 857 4 times, resulting in a remainder of 165.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 692 from 857 to get 165.
Append the next digit (8) from the dividend to 165 and continue with: 1658 / 173

Moving on to step 4:
When dividing 1658 by 173, we get 9 with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 101 after subtracting 1557 from 1658.
Include the next digit (4) from the dividend after 101, then repeat: 1014 / 173

Moving on to step 5:
The number 173 fits into 1014 5 times, leaving a remainder of 149.
Record the quotient 5 as the next digit in the result. 
Result so far: 495.0
If we subtract 865 from 1014, we get 149.
Take the next digit (0) from the dividend and append it to 149, then repeat: 1490 / 173

On to step 6:
The number 173 fits into 1490 8 times, leaving a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 4958.0
Subtracting 1384 from 1490 leaves us with 106.
Append the next digit (2) from the dividend to 106 and continue with: 1062 / 173

Let's proceed to step 7:
173 goes into 1062 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 49586.0
The remainder is 24 after subtracting 1038 from 1062.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 173

Step 8:
243 divided by 173 is 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 495861.0
The remainder is 70 after subtracting 173 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
The number 173 fits into 700 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 495861.4
Deduct 692 from 700 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 173 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 495861.4
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
173 goes into 800 4 times with a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 495861.404
The remainder is 108 after subtracting 692 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 12:
When dividing 1080 by 173, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 495861.4046
Subtract 1038 from 1080 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
173 can be fit into 420 2 times, resulting in a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 495861.40462
Subtracting 346 from 420 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
When dividing 740 by 173, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 495861.404624
Subtracting 692 from 740 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 15:
173 goes into 480 2 times with a remainder of 134.
Write down 2 as next digit of the result. 
Result so far: 495861.4046242
Subtracting 346 from 480 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 16:
173 goes into 1340 7 times with a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 495861.40462427
If we subtract 1211 from 1340, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 495861.40462427, with a leftover of 1.29e-07.
