86704998 divided by 173 
We want to figure out the number of times 86704998 can be divided by 173.

Going ahead to step 1:
When dividing 8 by 173, we get 0 with 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 173

Let's proceed to step 2:
173 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 173

Let's proceed to step 3:
173 can be fit into 867 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 865 from 867 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 173

Step 4:
20 divided by 173 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 173

Advancing to step 5:
When dividing 204 by 173, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 501.0
Subtract 173 from 204 to get 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 173

On to step 6:
173 can be fit into 319 1 times, resulting in a remainder of 146.
Put 1 as the next digit of the answer. 
Result so far: 5011.0
Subtract 173 from 319 to get 146.
Bring next digit (9) of the dividend behind the 146 and repeat the process: 1469 / 173

Going ahead to step 7:
173 goes into 1469 8 times with a remainder of 85.
Write down 8 as next digit of the result. 
Result so far: 50118.0
Subtract 1384 from 1469 to get 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 173

Going ahead to step 8:
If we divide 858 by 173, we get 4 and a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 501184.0
Deduct 692 from 858 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: 501184.9
Subtracting 1557 from 1660 leaves us 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.

Advancing 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: 501184.95
The remainder is 165 after subtracting 865 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
1650 divided by 173 is 9 with a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 501184.959
If we subtract 1557 from 1650, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 12:
If we divide 930 by 173, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 501184.9595
Subtracting 865 from 930 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
If we divide 650 by 173, we get 3 and a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 501184.95953
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.

On to step 14:
173 can be fit into 1310 7 times, resulting in a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 501184.959537
If we take 1211 away from 1310, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed 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: 501184.9595375
Subtract 865 from 990 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
173 goes into 1250 7 times with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 501184.95953757
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.

The final result is 501184.95953757 with a remainder of 3.9e-08.
