We're dividing 80404117 by 145 
We want to divide 80404117 by 145.

Step 1:
When dividing 8 by 145, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 145

Advancing to step 2:
When dividing 80 by 145, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 145

Going ahead to step 3:
145 goes into 804 5 times with a remainder of 79.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 725 from 804, we get 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 145

Moving on to step 4:
790 divided by 145 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtract 725 from 790 to get 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 145

On to step 5:
145 can be fit into 654 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 554.0
Subtract 580 from 654 to get 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 145

Going ahead to step 6:
If we divide 741 by 145, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 5545.0
Deduct 725 from 741 and we're left with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 145

Advancing to step 7:
145 can be fit into 161 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 55451.0
If we take 145 away from 161, we end up with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 145

On to step 8:
167 divided by 145 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 554511.0
Deduct 145 from 167 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 145 fits into 220 1 times, leaving a remainder of 75.
The next digit of our result is 1. 
Result so far: 554511.1
The remainder is 75 after subtracting 145 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
145 goes into 750 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 554511.15
If we take 725 away from 750, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
145 can be fit into 250 1 times, resulting in a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 554511.151
The remainder is 105 after subtracting 145 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 12:
The number 145 fits into 1050 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 554511.1517
Deduct 1015 from 1050 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
The number 145 fits into 350 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 554511.15172
If we take 290 away from 350, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
145 can be fit into 600 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 554511.151724
Deduct 580 from 600 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
The number 145 fits into 200 1 times, leaving a remainder of 55.
The next digit of our result is 1. 
Result so far: 554511.1517241
Deduct 145 from 200 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 16:
145 can be fit into 550 3 times, resulting in a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 554511.15172413
Subtract 435 from 550 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

In conclusion, the division gives 554511.15172413 with a balance of 1.15e-07.
