355669 ÷ 17 
We want to divide 355669 by 17.

Going ahead to step 1:
The number 17 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 17

Going ahead to step 2:
When dividing 35 by 17, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 34 from 35 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 17

Moving on to step 3:
If we divide 15 by 17, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 15, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 17

Moving on to step 4:
The number 17 fits into 156 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 209.0
Subtract 153 from 156 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 17

On to step 5:
When dividing 36 by 17, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2092.0
If we take 34 away from 36, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 17

Advancing to step 6:
The number 17 fits into 29 1 times, leaving a remainder of 12.
The next digit of our result is 1. 
Result so far: 20921.0
If we take 17 away from 29, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 17 fits into 120 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 20921.7
Deduct 119 from 120 and we're left 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.

Moving on to step 8:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 20921.7
If we subtract 0 from 10, we 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.
The number 5 becomes the next digit in our result. 
Result so far: 20921.705
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
If we divide 150 by 17, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 20921.7058
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
If we divide 140 by 17, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 20921.70588
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 20921.70588 with a balance of 4e-06.
