We look at the division of 121885 by 17 
Our goal is to divide 121885 by 17.

Advancing to step 1:
If we divide 1 by 17, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 17

On to step 2:
12 divided by 17 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 17

Step 3:
The number 17 fits into 121 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 2 after subtracting 119 from 121.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 17

Let's proceed to step 4:
The number 17 fits into 28 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 71.0
If we take 17 away from 28, we end up with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 17

On to step 5:
118 divided by 17 is 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 716.0
If we take 102 away from 118, we end up with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 17

On to step 6:
If we divide 165 by 17, we get 9 and a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 7169.0
The remainder is 12 after subtracting 153 from 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
When dividing 120 by 17, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7169.7
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
10 divided by 17 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7169.7
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 7169.705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
The number 17 fits into 150 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 7169.7058
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 17 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 7169.70588
Deduct 136 from 140 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.

In conclusion, the division gives 7169.70588 with a balance of 4e-06.
