78902871 ÷ 173 
Let's see how many times 173 fits into 78902871.

Moving on to step 1:
173 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 173

Let's proceed to step 2:
When dividing 78 by 173, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 173

Advancing to step 3:
The number 173 fits into 789 4 times, leaving a remainder of 97.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 692 from 789, we get 97.
Append the next digit (0) from the dividend to 97 and continue with: 970 / 173

Advancing to step 4:
173 goes into 970 5 times with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 105 after subtracting 865 from 970.
Grab the next digit (2) from the dividend, add it to 105, then carry on: 1052 / 173

Moving on to step 5:
The number 173 fits into 1052 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 456.0
Subtracting 1038 from 1052 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 173

Advancing to step 6:
173 can be fit into 148 0 times, resulting in a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 4560.0
Subtract 0 from 148 to get 148.
Append the next digit (7) from the dividend to 148 and continue with: 1487 / 173

Step 7:
173 goes into 1487 8 times with a remainder of 103.
Write down 8 as next digit of the result. 
Result so far: 45608.0
Subtracting 1384 from 1487 leaves us with 103.
Include the next digit (1) from the dividend after 103, then repeat: 1031 / 173

Advancing to step 8:
1031 divided by 173 is 5 with a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 456085.0
Deduct 865 from 1031 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
1660 divided by 173 is 9 with a remainder of 103.
Put 9 as the next digit of the answer. 
Result so far: 456085.9
If we take 1557 away from 1660, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 10:
1030 divided by 173 is 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 456085.95
Subtract 865 from 1030 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 11:
When dividing 1650 by 173, we get 9 with a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 456085.959
If we take 1557 away from 1650, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 12:
173 can be fit into 930 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 456085.9595
Subtract 865 from 930 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 13:
173 goes into 650 3 times with a remainder of 131.
The next digit of our result is 3. 
Result so far: 456085.95953
Subtracting 519 from 650 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 14:
173 goes into 1310 7 times with a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 456085.959537
If we subtract 1211 from 1310, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 15:
173 goes into 990 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 456085.9595375
If we take 865 away from 990, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 16:
The number 173 fits into 1250 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 456085.95953757
Subtracting 1211 from 1250 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 456085.95953757 with a balance of 3.9e-08.
