87693727 divided by 170 
Our goal is to divide 87693727 by 170.

Moving on to step 1:
8 divided by 170 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 170

On to step 2:
If we divide 87 by 170, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 170

On to step 3:
When dividing 876 by 170, we get 5 with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 850 from 876 leaves us with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 170

Moving on to step 4:
170 can be fit into 269 1 times, resulting in a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 170 from 269 and we're left with 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 170

On to step 5:
993 divided by 170 is 5 with a remainder of 143.
Use 5 as the next digit of our solution. 
Result so far: 515.0
Subtract 850 from 993 to get 143.
Fetch the next digit (7) from the dividend, attach it to 143 and continue: 1437 / 170

Moving on to step 6:
1437 divided by 170 is 8 with a remainder of 77.
Use 8 as the next digit of our solution. 
Result so far: 5158.0
Subtract 1360 from 1437 to get 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 170

Step 7:
The number 170 fits into 772 4 times, leaving a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 51584.0
If we subtract 680 from 772, we get 92.
Bring next digit (7) of the dividend behind the 92 and repeat the process: 927 / 170

Advancing to step 8:
170 can be fit into 927 5 times, resulting in a remainder of 77.
The number 5 becomes the next digit in our result. 
Result so far: 515845.0
Subtract 850 from 927 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
170 can be fit into 770 4 times, resulting in a remainder of 90.
The next digit of our result is 4. 
Result so far: 515845.4
Subtract 680 from 770 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
When dividing 900 by 170, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 515845.45
If we subtract 850 from 900, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
170 goes into 500 2 times with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 515845.452
Subtracting 340 from 500 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
1600 divided by 170 is 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 515845.4529
Subtract 1530 from 1600 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
The number 170 fits into 700 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 515845.45294
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 170, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 515845.452941
If we take 170 away from 200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 15:
170 goes into 300 1 times with a remainder of 130.
The next digit of our result is 1. 
Result so far: 515845.4529411
If we subtract 170 from 300, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The final outcome is 515845.4529411, with a leftover of 1.3e-06.
