801661 ÷ 17 
We're looking to find how many times 17 goes into 801661.

Let's proceed to step 1:
17 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 17

On to step 2:
When dividing 80 by 17, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 68 from 80 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 17

Advancing to step 3:
If we divide 121 by 17, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Subtracting 119 from 121 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 17

Step 4:
17 goes into 26 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 471.0
Subtract 17 from 26 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 17

Going ahead to step 5:
17 goes into 96 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 4715.0
The remainder is 11 after subtracting 85 from 96.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 17

Let's proceed to step 6:
If we divide 111 by 17, we get 6 and a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 47156.0
If we take 102 away from 111, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
17 goes into 90 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47156.5
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 8:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 47156.52
The remainder is 16 after subtracting 34 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 17 fits into 160 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 47156.529
Subtract 153 from 160 to get 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 10:
17 goes into 70 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 47156.5294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 17, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 47156.52941
Subtract 17 from 20 to get 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 12:
17 goes into 30 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 47156.529411
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 47156.529411 and a remainder of 1.3e-06.
