Let's divide 87054640 by 170
We're looking to find how many times 170 goes into 87054640.

Advancing to step 1:
If we divide 8 by 170, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 170

Advancing to step 2:
When dividing 87 by 170, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 170

Step 3:
If we divide 870 by 170, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 850 away from 870, we end up with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 170

Moving on to step 4:
When dividing 205 by 170, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 170 from 205 to get 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 170

Let's proceed to step 5:
If we divide 354 by 170, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
If we subtract 340 from 354, we get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 170

On to step 6:
If we divide 146 by 170, we get 0 and a remainder of 146.
Put 0 as the next digit of the answer. 
Result so far: 5120.0
Subtracting 0 from 146 leaves us with 146.
Append the next digit (4) from the dividend to 146 and continue with: 1464 / 170

Let's proceed to step 7:
1464 divided by 170 is 8 with a remainder of 104.
The next digit of our result is 8. 
Result so far: 51208.0
Subtracting 1360 from 1464 leaves us with 104.
Include the next digit (0) from the dividend after 104, then repeat: 1040 / 170

On to step 8:
When dividing 1040 by 170, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 512086.0
Subtract 1020 from 1040 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
170 can be fit into 200 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 512086.1
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.

Step 10:
170 can be fit into 300 1 times, resulting in a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 512086.11
If we take 170 away from 300, we end up with 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 512086.11, with a leftover of 0.13.
