85154175 ÷ 170 
We want to divide 85154175 by 170.

Going ahead to step 1:
When dividing 8 by 170, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 170

Advancing to step 2:
If we divide 85 by 170, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 170

Going ahead to step 3:
When dividing 851 by 170, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 850 from 851 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 170

On to step 4:
170 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 170

Let's proceed to step 5:
170 can be fit into 154 0 times, resulting in a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 500.0
Subtract 0 from 154 to get 154.
Take the next digit (1) from the dividend and append it to 154, then repeat: 1541 / 170

On to step 6:
If we divide 1541 by 170, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 5009.0
Subtracting 1530 from 1541 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 170

Step 7:
170 can be fit into 117 0 times, resulting in a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 50090.0
The remainder is 117 after subtracting 0 from 117.
Bring next digit (5) of the dividend behind the 117 and repeat the process: 1175 / 170

Let's proceed to step 8:
170 goes into 1175 6 times with a remainder of 155.
Put 6 as the next digit of the answer. 
Result so far: 500906.0
Deduct 1020 from 1175 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
If we divide 1550 by 170, we get 9 and a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 500906.9
If we take 1530 away from 1550, 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.

Step 10:
If we divide 200 by 170, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 500906.91
Subtracting 170 from 200 leaves us 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.

Moving on to step 11:
If we divide 300 by 170, we get 1 and a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 500906.911
The remainder is 130 after subtracting 170 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 500906.911 with a remaining 0.013.
