31169709 ÷ 170 
Our goal is to divide 31169709 by 170.

Moving on to step 1:
3 divided by 170 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 170

On to step 2:
If we divide 31 by 170, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 170

Going ahead to step 3:
170 goes into 311 1 times with a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 170 from 311, we get 141.
Append the next digit (6) from the dividend to 141 and continue with: 1416 / 170

Moving on to step 4:
1416 divided by 170 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 1360 from 1416, we get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 170

Moving on to step 5:
170 can be fit into 569 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 183.0
Subtract 510 from 569 to get 59.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 170

Moving on to step 6:
597 divided by 170 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 1833.0
If we take 510 away from 597, we end up with 87.
Append the next digit (0) from the dividend to 87 and continue with: 870 / 170

Step 7:
If we divide 870 by 170, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 18335.0
The remainder is 20 after subtracting 850 from 870.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 170

Advancing to step 8:
When dividing 209 by 170, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 183351.0
Subtract 170 from 209 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
390 divided by 170 is 2 with a remainder of 50.
The next digit of our result is 2. 
Result so far: 183351.2
If we subtract 340 from 390, 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.

Moving on to step 10:
When dividing 500 by 170, we get 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 183351.22
Deduct 340 from 500 and we're left 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.

The quotient of the division is 183351.22, and the remainder is 0.16.
