161715 ÷ 8 
Our goal is to divide 161715 by 8.

Step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 8

On to step 2:
The number 8 fits into 16 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 16 from 16 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 8

Let's proceed to step 3:
8 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 8

Step 4:
If we divide 17 by 8, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Deduct 16 from 17 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 8

Let's proceed to step 5:
8 goes into 11 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 2021.0
If we take 8 away from 11, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 8

Let's proceed to step 6:
When dividing 35 by 8, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 20214.0
If we take 32 away from 35, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 8, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 20214.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 20214.37
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20214.375
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20214.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20214.375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 20214.375, and the remainder is 0.0.
