121879 ÷ 17 
Our goal is to divide 121879 by 17.

Moving on to step 1:
17 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 17

Advancing to step 2:
12 divided by 17 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 17

On to step 3:
17 goes into 121 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 119 away from 121, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 17

Moving on to step 4:
The number 17 fits into 28 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 17 from 28 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 17

Advancing to step 5:
17 can be fit into 117 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 716.0
Deduct 102 from 117 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 17

Moving on to step 6:
If we divide 159 by 17, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 7169.0
The remainder is 6 after subtracting 153 from 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 17, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 7169.3
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
17 can be fit into 90 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 7169.35
Subtract 85 from 90 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 17, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 7169.352
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
17 can be fit into 160 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 7169.3529
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
17 goes into 70 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 7169.35294
Deduct 68 from 70 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
17 goes into 20 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7169.352941
Deduct 17 from 20 and we're left 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.

Let's proceed to step 13:
If we divide 30 by 17, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 7169.3529411
If we take 17 away from 30, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 7169.3529411 and a remainder of 1.3e-07.
