169403 divided by 80 
We're looking to find how many times 80 goes into 169403.

Let's proceed to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 80

Moving on to step 2:
The number 80 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 80

Moving on to step 3:
169 divided by 80 is 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 160 from 169 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 80

Step 4:
When dividing 94 by 80, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 80 from 94, we get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 80

Step 5:
When dividing 140 by 80, we get 1 with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 211.0
If we take 80 away from 140, we end up with 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 80

Let's proceed to step 6:
603 divided by 80 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 2117.0
Subtracting 560 from 603 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
80 goes into 430 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 2117.5
If we subtract 400 from 430, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 2117.53
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
80 goes into 600 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 2117.537
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2117.5375
Deduct 400 from 400 and we're left 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.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2117.5375
The remainder is 0 after subtracting 0 from 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 12:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2117.5375
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 final result is 2117.5375 with a remainder of 0.0.
