We're dividing 85879369 by 171 
Our goal is to divide 85879369 by 171.

Going ahead to step 1:
171 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 171

Advancing to step 2:
If we divide 85 by 171, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 171

Let's proceed to step 3:
If we divide 858 by 171, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 855 from 858, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 171

Step 4:
171 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 37, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 171

On to step 5:
171 goes into 379 2 times with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 502.0
Subtracting 342 from 379 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 171

On to step 6:
171 goes into 373 2 times with a remainder of 31.
The next digit of our result is 2. 
Result so far: 5022.0
If we take 342 away from 373, we end up with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 171

Going ahead to step 7:
When dividing 316 by 171, we get 1 with a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 50221.0
If we subtract 171 from 316, we get 145.
Grab the next digit (9) from the dividend, add it to 145, then carry on: 1459 / 171

Moving on to step 8:
The number 171 fits into 1459 8 times, leaving a remainder of 91.
The next digit of our result is 8. 
Result so far: 502218.0
If we take 1368 away from 1459, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
910 divided by 171 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 502218.5
The remainder is 55 after subtracting 855 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
171 can be fit into 550 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 502218.53
If we take 513 away from 550, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
171 goes into 370 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 502218.532
If we take 342 away from 370, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
171 can be fit into 280 1 times, resulting in a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 502218.5321
Subtracting 171 from 280 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 13:
171 can be fit into 1090 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 502218.53216
If we subtract 1026 from 1090, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
If we divide 640 by 171, we get 3 and a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 502218.532163
If we take 513 away from 640, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 15:
171 can be fit into 1270 7 times, resulting in a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 502218.5321637
Subtract 1197 from 1270 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 16:
171 can be fit into 730 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 502218.53216374
Subtracting 684 from 730 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 502218.53216374, with a leftover of 4.6e-08.
